Research and Development of Protein Bars and Optimization of Their Formulas
Soy protein isolate is a high-purity plant protein extracted from low-temperature desorbed soybean meal,which has the characteristics of high protein content and rich nutrition.Expanded soybean protein granules are the products obtained by extruding soybean protein isolate,cassava starch or rice noodles.The protein content of expanded soybean protein granules is about 80％,which gives a crispy feeling.The protein stick is composed of various proteins such as soy protein isolate,whey protein,puffed soy protein particles,pea protein,etc.,with added nutrients such as phospholipids and whole milk powder.It has the characteristics of high protein content and rich nutrition.The formula of the protein stick is optimized through single factor experiment and orthogonal experiment in the article,and the formula is determined to be mixed syrup 45.5％,soy protein isolate 17.1％,whey protein 9.5％,pea protein 4.7％,whole milk powder 7.1％,cocoa powder 3.1％,glycerin 4.0％,soybean oil 3.1％,phospholipids 1.2％,and chocolate 4.7％.The sensory and physicochemical indicators of the optimized protein stick product meet the quality requirements.
