Compound thickening agent for fish tofu

Abstract

The invention discloses a compound thickening agent for fish tofu. The compound thickening agent is characterized by being prepared from the following raw materials by percentage: 98-99% of modified starch, 0.5-1% of xanthan gum and 0.5-1% of konjac gum, wherein every 1% of the modified starch is prepared from the following raw materials by a weight ratio: 16-23% of acetylated distarch phosphate,16-17% of acetylated distarch adipate, 10-12% of hydroxypropyl distarch phosphate, 23-25% of starch acetate and 28-30% of starch phosphate. After the compound thickening agent for the fish tofu is used, the water absorption of the product is obviously improved, so that the product yield is increased; the compound thickening agent can increase the product yield by 2-3%. The compound thickening agent provided by the invention can improve the taste of the fish tofu, enhance the water-absorbing property and water-retaining property of the fish tofu, and improve the elasticity of the fish tofu. After the compound thickening agent is used, the freezing resistance and boiling fastness of the fish tofu can be improved, and the shelf life of the fish tofu can be prolonged.

Description

technical field [0001] The invention relates to a food additive, in particular to a compound thickener for fish tofu.
