preparation example Construction

[0025] The embodiment of the present invention provides a preparation method of freeze-dried fruit and vegetable milk, comprising the following steps:

[0026] a. Crush the fruit and / or vegetables, add fresh milk and mix well to obtain coarse pulp;

[0027] b. Sterilize the coarse pulp and cool it down;

[0028] c. Freeze-drying the sterilized coarse slurry to obtain a finished product.

[0029] Aiming at the problems of the prior art, the present invention provides a method for preparing freeze-dried fruit and vegetable milk. Fruits, vegetables, or fruits and vegetables are used together, after being pulverized, mixed with fresh milk to make a coarse slurry, and then dried Bacteria, freeze-dried to obtain the finished product.

[0030] The invention uses freeze-drying technology to remove moisture in fruits, vegetables and fresh milk. Freeze-drying technology, the full name of vacuum freeze-drying technology, freezes the raw materials to make the water change from liquid t...

Embodiment 1

[0056] A method for preparing freeze-dried fruit and vegetable milk, comprising the following steps:

[0057] a. Add sweet potato starch, then crush the fruit and vegetables mixed with sweet potato starch using wall-breaking technology, add fresh milk and mix well, then add fruit granules, and then add flavoring agent for seasoning to obtain a coarse slurry;

[0058] b. Sterilize the coarse pulp using ultra-high temperature instant sterilization technology, and cool it down;

[0059] c. Place the sterilized coarse pulp in a freeze-drying device, cool down to -50°C to -30°C for freezing, then vacuumize, heat up to 10°C to 50°C, make the water turn into water vapor and discharge, and obtain the finished product .

Abstract

The present invention discloses a preparation method of freeze-dried fruit and vegetable milk. The preparation method comprises the following steps: a, fruits and/or vegetables are crushed; fresh milkis added; and the materials are mixed evenly to obtain crude pulp; b, the crude pulp is sterilized; and the sterilized pulp is cooled; and c, the sterilized crude pulp is freeze-dried to obtain a finished product. The provided preparation method of the freeze-dried fruit and vegetable milk is simple and easy to operate; and the prepared product can retain nutrients and flavor substances, is goodin mouthfeel, rich in nutrients, and free of preservatives, and can be preserved for a long time. In addition, the finished product is light in weight, strong in rehydration, and easy to carry and consume.

Description

technical field [0001] The present application relates to the technical field of freeze-dried food, in particular to a method for preparing freeze-dried fruit and vegetable milk. Background technique [0002] Fruits and vegetables are rich in nutrients such as vitamins and dietary fiber, and are the daily necessities of human beings. But fruits and vegetables are difficult to store for a long time, and it is inconvenient to carry and eat. [0003] In the prior art, some people make fruit and vegetable juice to eat, but for long-term preservation, food additives such as various preservatives, preservatives, thickeners are often added in the fruit and vegetable juice. In addition, some people dry and dehydrate fruits and vegetables and make them into powder for consumption. However, during the drying process, the nutrient loss of fruits or vegetables is relatively serious, and the edible value is not high. [0004] Therefore, how to provide a kind of fruit and vegetable pro...
