Abstract

The invention discloses a soybean protein isolate-carrageenan mixed gel based on salt ions and a preparation method thereof. The gel comprises the following steps: deionized water is added into a beaker, the beaker is placed on a mixing apparatus, carrageenan powder is added, and a carrageenan solution is prepared; the soybean protein isolate solution and the prepared carrageenan solution are mixed, in order to prepare a soybean protein isolate-carrageenan mixed solution; a salt solution is added into the soybean protein isolate-carrageenan mixed solution, the solution is placed on a magneticmixing machine for stirring, so that solid powder is completely dissolved. Salt ions are added, a soybean protein isolate-carrageenan mixed gel molecule arrangement mode is changed, carrageenan occupies the aqueous phase, and viscosity of fluid is increased; adaptability, frequency resistance and strain resistance of the soybean protein isolate-carrageenan mixed gel are improved.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a soybean protein isolate-carrageenan mixed gel and a preparation method thereof. Background technique [0002] Soybean protein isolate is a kind of high-quality vegetable protein produced from low-temperature defatted soybean meal, which is obtained from the by-product of soybean oil industry. Soybean protein isolate mainly contains soybean globinin and 90% soybean protein, which contains essential amino acids for human body and has high nutritional value. Soy protein isolate is a food ingredient, because of its nutritional value and functional properties, such as gelling, emulsifying, etc., it has attracted great attention and its demand continues to grow. And because of its unique functional properties, it promotes the wide application of soybean protein isolate in food processing. Soy protein has the ability to form a gel when heated. The gel can solidif...
