SOY HULLS: INEXPENSIVE AND VERSATILE INDUSTRY BY-PRODUCT

Abstract

This paper reviews the potential applications of soybean hulls and their conversion into value-added products. In recent years, importance has been given to solving the problems of negative effects of fossil fuels, general pollution and the growing demand for environmentally friendly and sustainable alternatives. The increased worldwide demand for animal feed and plant protein directly affects the increase in soybean production and the generation of large amounts of by-products. By valorizing by-products, it is possible to reduce the impact of waste on the environment, solve the problem of malnutrition and close the circular economy loop. The main uses of soybean hulls are in the production of biofuels, application in animal feed, production of industrially important enzymes, synthesis of biomaterials and functional food ingredients.

Ovaj rad daje pregled potencijalnih primena sojinih ljuski i njihove konverzije u proizvode sa dodatom vrednošću. Poslednjih godina se značaj pridaje rešavanju problema negativnih efektata fosilnih goriva, opšteg zagađenja i porasta potražnje za ekološki prihvatljivim i održivim alternativama. Povećani zahtevi za hranom za životinje i proteina biljnog porekla širom sveta direktno utiču na povećanje proizvodnje soje i generisanje velikih količina nusproizvoda. Valorizacijom nusproizvoda moguće je smanjiti uticaj otpada na životnu sredinu, rešiti problem neuhranjenosti i zatvoriti petlju cirkularne ekonomije. Glavne upotrebe sojinih ljuski su u proizvodnji biogoriva, primeni u stočnoj hrani, proizvodnji industrijski značajnih enzima, sintezi biomaterijala i funkcionalnih sastojaka hrane.
