Constant world population growth imposes the need for the production of
more food, and as a consequence, has an increase in the organic-rich wastes.
These agro-industrial wastes represent problem from the environmental
viewpoint, and their utilization as the raw materials for the production of
value-added products has become one of the main topics of the biorefinery.
The aim of this research was to use soybean meal, co-product of dietary oil
production, as a model agro-industrial byproduct for optimization of phenolic
compounds extraction. In this paper, ethanol influenced microwave-assisted
extraction is chosen since it is recognized as eco-friendly and food-safe.
In this paper, we used soybean meal, co-product of dietary oil production, as
a model agro-industrial by-product for optimization of phenolic compounds
extraction. Ethanol influenced microwave-assisted extraction is chosen
since it is recognized as eco-friendly and food-safe. Optimization of the
extraction inclu...ded finding the: optimal liquid/solid ratio, extraction duration,
and microwave power. The same method was applied for the extraction of
phenolics from apple pomace, apple pomace mixed with soybean meal,
ultrasound-treated soybean meal, and wheat bran. Antioxidative potential
of all extracts was evaluated using a fixed reaction time 2,2-diphenyl-1-
picrylhydrazyl (DPPH) method as well as a steady-state measurement DPPH
method. 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) i.e., ABTS
and ferric reducing antioxidant power (FRAP) methods were applied as well. Under optimized conditions (liquid/solid ratio of 15 mL/g for 70 s at a microwave
power of 300 W) 3.87 mg gallic acid equivalent (GAE)/g was extracted from
soybean meal, which represented a substantial increase compared to 2.46
mg GAE/g obtained before optimization. Results showed that extracts had
different behavior towards different radicals depending on the type of the
extracted phenolics. Apple pomace extract was the most potent towards
DPPH radical, while the most effective extract towards ABTS radical was
obtained from apple pomace and soybean meal mixture. Soybean meal
extract showed the highest reducing power assessed via the FRAP method.
Results obtained in this study show that optimization of the extraction enabled
a substantial increase in the extracted phenolics and that the method could
be successfully applied with other agro-industrial by-products providing
extracts with antioxidative potential.
