AB  - In this study, a new product was evaluated: enriched dark chocolate with two encapsulated plant extracts: Salvia Lavandiulaefolia and Salvia officinalis with the addition of fruit extract Malpighia glabra (acerola). Physico-chemical characteristics, antioxidant, and sensory properties of chocolate with extracts (AC300, AC400, and AC500) were determined in relation to chocolate without additives (DC). The analysis showed that according to the hardness, enthalpy, and sensory analysis, AC 400 chocolate (sample with 36.34 g of dark chocolate, 0.256 g Acerola extract, and 0.4 g Cognivia™ extract) had the best characteristics, while the rheology and particle size distribution was almost identical in all three samples of functional chocolates. A small amount of extracts did not cause changes in the structure of chocolate, but it significantly improved the polyphenolic status of chocolate and antioxidant activity. The results of the antioxidant activity tests showed that the best sample was AC 500 (sample with 36.24 g of dark chocolate, 0.256 g Acerola extract, and 0.5 g Cognivia™ extract), in which the total polyphenol content was the highest, as well as a level of compounds that inhibit AChE activity.

AB  - In order to improve functional characteristics of standard milk chocolate (C) was enriched by the addition of whey protein concentrate (WPC) and whey proteins hydrolyzed by trypsin (H-WPC) in the amount of 6%. The chocolate samples were analyzed by determination of antioxidant capacity, particle size distribution, textural, rheological, and sensory properties. The obtained results revealed that chocolate enriched by whey protein hydrolysate (H-WPC) possesses higher content of total polyphenols (1007.8 ± 96.8 mg GAE/100g), increased ability to inhibit ABTS radicals (66.30 ± 1.99%), and increased ability to inhibit DPPH radicals (56.34 ± 3.20%), compared to the standard milk chocolate (C) (877.1 ± 56.0 mg GAE/100g; 48.46 ± 2.11%; 48.07 ± 2.80%, respectively). The additional ingredients do not significantly affect the hardness and enthalpy of chocolates. The hydrolyzed whey proteins increase the viscosity of chocolate (11.81 ± 0.11 Pa·s) to a greater extent than non-hydrolyzed whey proteins (9.17 ± 0.09 Pa·s), relative to the control sample (3.53 ± 0.05 Pa·s). Regardless of the fact that the WPC sample has slightly better rheological characteristics and particle size distribution compared to the H-WPC sample, no major changes in the sensory characteristics of chocolate were observed. Based on the results, whey protein hydrolysate can be marked as an exceptional ingredient for improving the quality of chocolate.

AB  - White chocolate is considered an unhealthier product than dark and milk chocolate due to the absence of cocoa solids containing polyphenols and other valuable components such as minerals and dietary fiber. This paper aimed to improve the nutritional value of white chocolate (C) by adding blueberry bioactive compounds. Since natural polyphenols are easily degradable because of their sensitivity, whey, as a rich source of proteins, was used as a material for encapsulating blueberry juice. Whey proteins protect blueberry anthocyanins and increase their bioaccessibility in the human body. Blueberry juice encapsulates (B) were added to white chocolate, replacing 8% (C-B8) and 10% (C-B10) of white chocolate mass. Blueberry encapsulates significantly (p < 0.05) increased the viscosity of chocolates (from 0.63 Pa·s in C to 1.13 Pa·s in C-B8 and 1.40 Pa·s in C-B10) with no significant impact on their melting peak. Both enriched chocolates had significantly (p < 0.05) higher protein and dietary fiber content and lower fat content than white chocolate. The total polyphenol content increased 3.7-fold, while antioxidant capacity increased 5.2-fold in C-B10. The oxidation stability, determined by pressurized accelerated oxidation, was also improved in enriched chocolates. Blueberry juice encapsulated in whey positively influenced the color and sensory characteristics of fortified white chocolates, where C-B10 had higher sensory scores for blueberry odor and taste than C-B8. The obtained results open up a possible pathway and indicate opportunities and limitations for the incorporation of other materials, such as various dietary/fruit components, in white chocolate.

AB  - Resistant starch (RS) is a part of insoluble dietary fiber, and it could be recognized as a functional food ingredient in some types of confectionery products that lack dietary fiber. Unlike dark and milk chocolate, white chocolate does not contain fat-free cocoa solids rich in dietary fiber. In the present study, 5%, 10%, and 15% of white chocolate were substituted with RS in order to improve the nutritional value of enriched white chocolate. The influence of RS on rheological, textural, and thermal properties of the chocolate fat phase was firstly investigated, and then further influence on physical properties, dietary fiber content, and sensory characteristics of enriched white chocolates were investigated. The obtained results showed that enriched chocolates had increased content of total dietary fiber and reduced total fats and protein content in accordance with the added amount of RS. At the same time, RS increased viscosity and reduced the hardness and volume mean diameter in enriched chocolates in accordance with the added amount. RS improved the nutritional composition of white chocolate by increasing the content of dietary fiber. At the same time, RS did not impair the color and sensory characteristics of enriched white chocolates.

AB  - The aim of this chapter was to introduce chocolate as a cocoa carrier of probiotics and bioactive whey protein hydrolysate. This research examined the influence of additional ingredients on the functional properties and rheology of the final product. The chocolate prepared with L. rhamnosus HN001 strain at 40°C achieved the highest survivability, which was above 90% (viable cell count of about 8.1 log (CFU/g)) after 6 months of storage. This strain could be selected for high-quality probiotic chocolate production. The addition of probiotic L. rhamnosus HN001 significantly improves the rheological properties of probiotic chocolate. The addition of bioactive whey protein hydrolysate did not show significant changes in the total content of polyphenols or ABTS radical scavenging activity. However, DPPH radical scavenging activity showed an increase of 1.28 times during storage and about 1.46 in relation to the control sample and the sample supplemented with unhydrolyzed whey proteins. The bioactive whey protein hydrolysate affects chocolate rheology by increasing the thixotropic loop 8.02 times in relation to the control sample, and 1.57 times compared to the sample supplemented with unhydrolyzed whey proteins. Based on the results, the addition of probiotics and bioactive whey protein hydrolysate powder in industrial conditions, which was done in the mixing tank (at 40°C) before the chocolate shaping phase, provides preservation of both functional ingredients as key components for this type of product. The addition of probiotics improves the rheological properties of chocolate, while the addition of whey protein hydrolysate leads to undesirable viscosity increase that can be avoided using a more efficient emulsifier.

AB  - The aim of this study was to determine the effect of the main milling variables, i.e., agitator shaft speed (50, 75 and 100%, which is 25, 37.5 and 50 rpm) and milling time (30, 45 and 60 min) on physical and sensory properties of fat tilling as well as on energy consumption during the production in a laboratory ball mill. Within the response surface method, the face centered central composite design is used. A response surface regression analysis for responses was performed and a full quadratic model was fitted to the experimental data. It is shown that agitator shaft speed had the most significant influence on physical properties (particle size distribution, rheological and textural propertes) and sensory characteristics of fat tilling while the milling energy consumption is highly influenced by milling time with contribution 55.4%, followed by agitator shaft speed (40.04%). The model obtained by regression analyses was used to perform the optimization of processing parameters in order to provide the combination of agitator shaft speed and milling time that cost less energy while at the same time do not compromise the quality of the fat filling. Optimization of production of fat filling in a laboratory ball mill would imply the maximum agitator shaft speed and 30-min milling time.

abstract = "The aim of this study was to determine the effect of the main milling variables, i.e., agitator shaft speed (50, 75 and 100%, which is 25, 37.5 and 50 rpm) and milling time (30, 45 and 60 min) on physical and sensory properties of fat tilling as well as on energy consumption during the production in a laboratory ball mill. Within the response surface method, the face centered central composite design is used. A response surface regression analysis for responses was performed and a full quadratic model was fitted to the experimental data. It is shown that agitator shaft speed had the most significant influence on physical properties (particle size distribution, rheological and textural propertes) and sensory characteristics of fat tilling while the milling energy consumption is highly influenced by milling time with contribution 55.4%, followed by agitator shaft speed (40.04%). The model obtained by regression analyses was used to perform the optimization of processing parameters in order to provide the combination of agitator shaft speed and milling time that cost less energy while at the same time do not compromise the quality of the fat filling. Optimization of production of fat filling in a laboratory ball mill would imply the maximum agitator shaft speed and 30-min milling time.",

AB  - The aim of this study was to investigate the survival of probiotics (Lactobacillus acidophilus NCFM, Lactobacillus rhamnosus HN001 and Bifidobacterium lactis HN019) in milk chocolate masses prepared at temperatures 35 degrees C and 40 degrees C. The influence of probiotics and preparation temperature on rheology, particle size distribution and sensory properties of the chocolates, was examined during 6 months of storage at 20 +/- 2 degrees C. An inoculation temperature of 40 degrees C significantly improves the rheological and sensory properties of probiotic chocolate, as well as leading to the survival of L. acidophilus NCFM and L. rhamnosus HN001 strains. After 6 months of storage, the survival of these strains was above 90%, with a viable cell count of about 8.1 log(CFU g(-1)). An inoculation temperature of 40 degrees C provides higher scores of overall sensory quality (4.52-4.68), higher quality category (excellent), lower maximal viscosity (for 1.2 Pa s) of chocolates, than a temperature of 35 degrees C. Compared to the chocolate without probiotics, those inoculated at 40 degrees C achieved less increase in volume weighted mean diameter distribution (average 0.8%) than chocolates inoculated at 35 degrees C. Based on the results reported in this paper, seeding of the probiotics in industrial conditions can be done in the mixing tank (at 40 degrees C) before the phase of chocolate shaping. Addition of probiotics at this stage facilitates the manufacturing process, improves the overall quality of chocolate and preserves the probiotics as a key component of this type of product.

AB  - This research examined spreadable cocoa cream in which fat phase has been modified and analyzed regarding its crystallization and rheological properties and further influence on final product quality. Vegetable fat and refined sunflower oil, as fat phase of spreadable cocoa cream, have been partially substituted with rapeseed and sesame oil, having nutritional and sensory benefits in mind. Substitution of sunflower oil with rapeseed or sesame oil had no influence on cream fat phase viscosity but increased cream viscosity up to 1.7 times and decreased its yield stress up to 2.7 times. Substitution of 70 wt % and total amount of sunflower oil with rapeseed or sesame oil resulted in lower crystallization rate in cream fat phase and the highest sensory scores of final products. Rapeseed and sesame oil have changed and improved the taste of spreadable cocoa cream making it sustainable for use in new products, but with shorter shelf life. Practical ApplicationsSpreadable cocoa cream is a confectionery product having a high amount of sugar and fat. In recent decades, confectionary industry in Serbia has used hydrogenated fats in spreadable cocoa cream production and also refined sunflower oil, to improve spreadability of the final product. Today, the development of functional foods imposes the use of edible fats with no undesirable trans fatty acids, instead of those obtained by common hydrogenation process. As manufacture of cream product in the ball mill does not require high temperatures during its production, refined sunflower oil can also be substituted with less resistant unrefined oils with different distinctive flavor and health benefits, such as rapeseed and sesame oil.

AB  - The rheological properties of spreadable cocoa cream containing lecithin of different origins (sunflower, rapeseed and soy lecithin) were investigated within this research. A laboratory ball mill was used to produce creams containing varying amounts of lecithin (0.3, 0.5 and 0.7 wt%). The effect of milling time was also studied (between 30, 40 and 50 min). Comparison between the different origins of lecithin revealed sunflower lecithin to be lower in viscosity than soy or rapeseed lecithin. Sunflower and rapeseed lecithins have a higher phosphatidilcholine content than soy lecithin. Increasing the lecithin concentration decreased the crystallization rate and increased the peak and conclusion temperatures in the cream fat phase. The type of lecithin used had no significant influence on the fat phase viscosity. It is found that the optimal rheological properties of spreadable cocoa cream can be achieved using 0.5 wt% of soy and rapeseed lecithin or 0.7 wt% of sunflower lecithin and 40-min milling time.

AB  - Crystallization and physical properties of nontrans vegetable fat with the addition of soybean, sunflower and rapeseed lecithin were investigated in this paper. NMR technique was used for measuring the solid fat content of fats at different temperatures, as well as for crystallization rate under static conditions. Also, the possibility of applying Gompertz function to define kinetics of crystallization was investigated. Rheological and textural properties were determined using the rotational viscometer and texture analyzer, whereas thermal properties were obtained by differential scanning calorimetry (DSC). The addition of lecithin from different sources does not affect the crystallization characteristics of nontrans edible fat, whereas rheological and textural tests confirmed that the addition of lecithin in excess increases the complexity of the system. DSC measurement confirmed the presence of three fractions in fat with different melting properties. The addition of lecithin from different sources has a significant effect on energy required for melting and some effect on other thermal properties of nontrans edible fat. Practical ApplicationsSoybean seeds are the main source of lecithin in confectionery industry in Serbia and elsewhere. The extensive production of sunflower and rapeseed oil opens the possibility of using lecithin from these sources as an alternative. Also, the development of functional foods dictates the use of edible fats with no undesirable trans fatty acids, obtained by fractionation and transesterification instead of common hydrogenation process. The impact of lecithin from different sources on crystallization and physical properties of pure nontrans fat is the base for this research. The lecithin obtained from sunflower and rapeseed should be further examined in different confectionery products with continuous fat phase, and should appropriate emulsifying properties are achieved, they could be used in the confectionery production as well.

AB  - Properties of chocolate depend on raw chocolate composition, manufacturing process and properly guided phase of precrystallization. In this paper chocolate was produced in a nonconventional way, in the ball mill. Milk powder, as most commonly used raw material for milk chocolate production, was replaced with soy milk powder. In Western countries, soya milk is used in a diet of people who are intolerant to lactose, or who do not consume foods of animal origin. Three types of chocolate have been produced: R1 chocolate mass with 20% cow milk powder, chocolate mass R2 with 15% soy milk powder and R3 chocolate mass with 20% soy milk powder in laboratory ball mill. The aim of this research was to examine the influence of the milk powder and soya milk powder (15% and 20%) on the total phenolic content. The total phenolic content (TPC) increased with the increase of soya milk content in chocolate samples. Antiradical scavenging activity was in a direct relationship with the total phenolics content. The lowest IC50 showed the sample of chocolate with 20% of soya milk.

AB  - The rheological and physical properties of the chocolate mass depend on the ingredient composition as well as the manufacturing process. For the purpose of this work, a milk chocolate mass of identical composition and raw materials was manufactured by using the two different manufacturing processes: a standard manufacturing process (SM) in five-roller mills including conching, and an unconventional manufacturing process in a ball mill (R1). The quality of both milk chocolate masses was examined by the comparison of thermal (differential scanning calorimetry analysis), textural properties (texture analysis), and the content of hard triglycerides (nuclear magnetic resonance spectroscopy). The main goal of this work was to determine whether chocolate can be produced in a ball mill, using the manufacturing process which results in significant savings, without causing drastic changes to the chocolate physical properties. The new manufacturing process rationalises the standard method by combining two phases, namely conching, and refining into a single one. This results in reduced initial and maintenance costs, as well as costs of workforce and fuel, etc. The results have shown that the new chocolate manufacturing process has a positive impact on texture and thermal properties, while the content of hard triglycerides remains the same.

abstract = "The rheological and physical properties of the chocolate mass depend on the ingredient composition as well as the manufacturing process. For the purpose of this work, a milk chocolate mass of identical composition and raw materials was manufactured by using the two different manufacturing processes: a standard manufacturing process (SM) in five-roller mills including conching, and an unconventional manufacturing process in a ball mill (R1). The quality of both milk chocolate masses was examined by the comparison of thermal (differential scanning calorimetry analysis), textural properties (texture analysis), and the content of hard triglycerides (nuclear magnetic resonance spectroscopy). The main goal of this work was to determine whether chocolate can be produced in a ball mill, using the manufacturing process which results in significant savings, without causing drastic changes to the chocolate physical properties.

AB  - Spreads are confectionery products based on sugar, vegetable fat, cocoa powder, milk powder and other ingredients. Basic properties of these products are good spreadability in wide temperature range (from ambience to fridge temperature), rich creamy chocolate taste, and homogenous smooth structure without oil phase migration. The undesirable attribute of these products is their relatively high energy value (2300 kJ/100 g). In recent years, cocoa cream products with reduced energy values have become very popular among consumers and today they are present in the assortment of many confectionery manufacturers. One way to produce spreads with reduced energy value is the replacement of sugar (sucrose) with adequate sweetener. Maltitol is a low-energy polyol capable to qualitatively and quantitatively replace sucrose. Cocoa spreads with maltitol and with the combination of maltitol and sucrose (produced at different temperatures and mixer rotation speeds) have similar texture and rheological properties compared to the spreads with sucrose. The spreads with maltitol have about 15% lower energy value in comparison to the same product with sucrose.

AB  - Chocolate is a complex rheological system in which non-fat cocoa particles and sugar particles are enveloped by crystal matrix of cocoa butter. Physical properties of chocolate depend on ingredient composition, method of production and properly performed pre-crystallization phase. In this work, chocolate was produced in an unconventional way, i.e., in a ball mill applying variable refining time (30, 60 and 90 min) and pre-crystallization temperature in chocolate masses (26, 28 and 30 °C). Two types of chocolate were produced: chocolate with 20% of powdered cow's milk (R1) and chocolate with 20% of soya milk powder (R2). The quality of chocolate was followed by comparing nutritive composition, polyphenol content, hardness of chocolate, solid triglyceride content (SFC) and rheological parameters (Casson yield flow (Pa), Casson viscosity (Pa s), the area of the thixotropic loop, elastic modulus and creep curves). The aim of this paper is determining changes caused by replacing cow's milk with soya milk powder in respect of nutritive, rheological and sensory properties, as well as defining optimal parameters: precrystallization temperature and refining time of soya milk chocolate in order to obtain suitable sensory and physical properties identical to those of milk chocolate mass. The results show that replacing powdered cow's milk with soya milk powder affects the increase in nutritive value of soya milk chocolate. R2 chocolate mass showed the increase in essential amino acids and fatty acids. This chocolate mass also showed the increase in total polyphenols by 28.1% comparing to R1 chocolate mass. By comparing viscosity, yield stress, shear stress and the area of the thixotropic loop, it can be observed that R1 chocolate mass represents a more organized and simpler system than the mass with soya milk (R2), as it shows lower values for all the above mentioned parameters, regardless of the refining time and pre-crystallization temperature. Viscoelastic behavior of R2 is also evident, as a consequence of soya protein presence. In order to maintain optimal hardness as well as melting resistance of chocolate, in case of R2 chocolate mass it is necessary to apply pre-crystallization temperature of 26°C, while for the chocolate mass R1 it is 30°C.
AB  - Čokolada je složen reološki sistem u kome su nemasne kakao čestice i čestice šećera obavijene kristalnim matriksom kakao maslaca. Fizičke karakteristike čokolade zavise od sirovinskog sastava, postupka proizvodnje i pravilno vođene faze pretkristalizacije. Za istraživanja, proizvedena je čokolada na nekonvencionalni način, odnosno u kugličnom mlinu uz variranje vremena usitnjavanja (30, 60 i 90 min) i temperatura pretkristalizacije (26, 28 i 30°C). Proizvedene su dve vrste čokolade, čokolada sa 20% kravljeg mleka u prahu (R1) i čokolada sa 20% sojinog mleka u prahu (R2). Kvalitet čokolada je praćen upoređivanjem nutritivnog sastava, sadržaja polifenola i antioksidativne aktivnosti, čvrstoće čokolada, sadržaja čvrstih triglicerida i reoloških parametara (prinosno proticanje po Cassonu (Pa), viskozitetet po Cassonu (Pa s), površina tiksotropne petlje, moduli elastičnosti i krive puzanja). Cilj ovog rada je da se utvrde promene koje izaziva zamena kravljeg mleka sojinim mlekom u prahu u nutritivnom, reološkom i senzornom smislu i da se pronađu optimalni parametri: temperatura pretkristalizacije i vreme usitnjavanja čokolade sa sojinim mlekom kako bi se postigle odgovarajuće senzorne i fizičke osobine identične mlečnoj čokoladnoj masi.
