Milk-containing food embedded with nuts and preparation method thereof

Abstract

The invention belongs to the technical field of milk-containing food preparation, and specifically relates to preparation process of a milk-containing food embedded with nuts which is molded by performing jetting-casting. The preparation process of the milk-containing food embedded with the nuts comprises the following steps: (1) mixing components, namely raw materials and auxiliary materials, weighed according to a proportion so as to obtain milk-containing slurry, wherein the water content of the milk-containing slurry is 25-35%; (2) performing jetting-casting on the milk-containing slurry by adopting a jetting-casting technology so as to have the milk-containing slurry molded, thereby obtain molded slurry; (3) embedding the bottom part, the middle part or the upper part of the molded slurry with nut particles, wherein the embedding quantity of the nut particles accounts for 1-20% of the quantity of the milk-containing food; and (4) performing vacuum drying on the molded slurry embedded with the nut particles so as to obtain a finished product. The milk-containing food prepared by the preparation process provided by the invention is high in milk solid content; and moreover, the milk-containing food is embedded with nuts, so that the milk-containing food is richer in nutrients. Thus, the milk-containing food embedded with the nuts can be taken as a dairy product capable of supplementing milk nutrients. In addition, the water content of the milk-containing solid food prepared by the preparation process can be precisely controlled below 3.0%, and the shelf life can be up to2 years.

Description

technical field [0001] The invention belongs to the technical field of milk-containing food preparation, and in particular relates to a spray-casting-molded milk-containing food embedded with nuts and a preparation method thereof. Background technique [0002] At present, the types of milk-containing solid formed foods on the market are mainly stamped milk flakes and extruded milk bars. The production process of milk tablets mainly includes dry blending, wet blending, granulation, drying, and then stamping. [0003] For example, Chinese invention patent application CN201710029143.9 discloses a method for preparing low-sugar and low-fat milk tablets rich in diglycerides. The operation steps of the method are as follows: 1) Milk fat is prepared into milk fat diglyceride by enzyme-catalyzed glycerol hydrolysis; 2) Whey protein is prepared into a solution, mixed with milk fat diglyceride and sucrose fatty acid ester, and dispersed by high speed and high pressure homogenization....

AI Technical Summary

Problems solved by technology

The process is complicated and the cost is high; it cannot be sterilized in production, and the microorganisms are difficult to control; nut powder, due to its high fat content and exposure on the surface, is easily oxidized and deteriorated, and it is difficult to preserve; compared with nut grains, nut powder has a much worse taste
