KIZILÖTESİ, MİKRODALGA, ULTRASES TEKNOLOJİLERİ VE KOMBİNASYONLARI KULLANILARAK MODİFİYE EDİLMİŞ DOĞAL BİYOPOLİMERLERİN ÇEŞİTLİ ÖZELLİKLERİ ÜZERİNE BİR DERLEME

Natural biopolymers are environmentally friendly, green polymers, used in various fields, such as food production, food packaging, textile, otomotive, medicine, drug, etc. Modification of natural biopolymers by use of different technologies can improve their functionalities. Modified natural biopolymers can be used as an encapsulation material, an ingredient of high performance edible film, coating or a functional food. Infrared, microwave and ultrasound and their combinations can degrade and depolymerize natural biopolymers and affect their functionalities in a positive manner, according to their specific action mechanisms. Ultrasound and ultrasound-microwave combination technologies can increase extraction and enzymatic hydrolysis yield, decrease process time and improve properties of polymers. In this paper, action mechanisms of infrared, microwave and ultrasound technologies were mentioned briefly, various properties of natural biopolymers modified by those technologies and effects of ultrasound and ultrasound-microwave combination technologies on yield, process time of extraction and enzymatic hydrolysis processes were featured.
