Abstract

The invention relates to a composite fat simulant, the composition and weight parts of which are as follows: whey protein particle dispersion liquid: 50-75 parts; xanthan gum system: 14-40 parts; pectin system: 6-10 parts ; Composite additives: 4 to 9 parts. The simulant of the present invention is compounded with a certain proportion of xanthan gum system, pectin system and whey protein particle system, and the obtained sample has a strong milky fragrance and no peculiar smell; after being sent, fine foam can be formed inside the sample, which can It is a good simulation of the properties and texture of cream products, and can significantly improve the rough taste and instability of the state when a single colloid and protein system are compounded; this simulant can reduce or even replace cream products in cake decoration and other non-high temperature applications Handle high-fat food; by adjusting the mixing ratio of whey protein particle dispersion and colloid system, fat simulants with different textures can be obtained, which can reduce or even replace cream products, and can be used in the processing of low-fat food, expanding its scope of use.

Description

technical field [0001] The invention belongs to the technical field of food ingredients, in particular to a composite fat simulant and a preparation method thereof. Background technique [0002] Excessive fat intake is one of the important causes of obesity and cardiovascular disease. With the development of society and the improvement of living standards, people have generally realized that excessive intake of fat is harmful to health, but reducing the amount of fat will deteriorate the palatability and processing performance of food. Applying fat simulants to the production of high-fat products can not only reduce the calories of food, but also ensure that the products have good taste, texture and corresponding processing performance. [0003] At present, fat mimics can be roughly divided into three categories: chemically synthesized fat matrix, protein matrix and carbohydrate matrix mimics. Chemosynthetic fatty matrix mimics are limited in application due to their tende...
