The reaction of raw globulin preparations from sunflower seed with a 10-30-fold excess of succinic anhydride results in a maximum blockage of 85-92 % of the protein amino groups. The water absorption of the protein increases 2-fold after a 26 % succinylation and nearly 6-fold after an exhaustive mo

The glycerol 3-phosphate acyltransferase (GPAT, EC 2.3.1.15) from sunflower (Helianthus annuus L.) microsomes has been characterised and partially purified. The in vitro determination of activity was optimized, and the maximum value for GPAT activity identified between 15 and 20 days after flowering

Microwave roasting is unique and has gained acceptance in food preparation because of its convenience, efficiency, speed and low operating costs. The microwave heating of a food is caused by molecular friction between electrical dipoles under an oscillating electric field of a specific frequency. Th
