A freeze-dried composite fruit and vegetable granule with high nutritional value and rapid disintegration

Abstract

The invention discloses a processing method of freeze-dried composite fruit and vegetable grains with high nutrient value and capable of quickly disintegrating. The processing method comprises the following steps of (1) preparing fruit and vegetable raw pulp; (2) uniformly mixing several or all of 20-70 parts by weight of pawpaw raw pulp, 20-70 parts by weight of purple cabbage raw pulp, 10-60 parts by weight of potato raw pulp, 10-60 parts by weight of guava raw pulp, 10-60 parts by weight of mango raw pulp, and 10-60 parts by weight of passion flower raw pulp to obtain fruit and vegetable mixed pulp; (3) injecting the fruit and vegetable mixed pulp into a mold, and quickly freezing for forming to obtain composite fruit and vegetable grains; (4) carrying out drying processing on the composite fruit and vegetable grains by adopting a freeze drying method to obtain freeze-dried composite fruit and vegetable grains; and (5) packaging the product. The composite fruit and vegetable grains have strong antioxidation capability and rich active ingredient content, are capable of effectively reducing the oxidation stress of a human body and improving the immunity of the human, are strong in disintegrating capability and have the characteristic of just melting in the mouth.

Description

technical field [0001] The invention relates to a freeze-dried fruit and vegetable solid food, especially freeze-dried composite fruit and vegetable granules with high nutritional value and fast disintegration developed for people with low immunity and difficulty in swallowing solid food, belonging to the technical field of fruit and vegetable food structure. technical background [0002] As we all know, the human body will constantly produce and remove free radicals in the process of metabolism. Free radicals can cause human aging, diabetes, cancer and other diseases. Fruits and vegetables are rich in polyphenols, vitamins and other plant active ingredients, which are natural antioxidants that scavenge free radicals. It has been proved by medicine that the human body is prone to diseases caused by oxidative stress in an oxygen-rich state, and the human body's disease rate can be reduced by adding fruit and vegetable supplementary foods rich in antioxidant components.

Problems solved by technology

Due to the defective chewing function of infants, the elderly and the mentally ill, solid food cannot be swallowed normally, but the development of fruit and vegetable solid food for this group of people is less

At present, fruit and vegetable products mainly include fruit and vegetable juice, fruit and vegetable puree and fruit and vegetable slices, etc. Among them, fruit and vegetable juice and fruit and vegetable puree cans are prepared by traditional processing methods, which have the disadvantages of low nutritional value and inconvenient to carry when going out; fruit and vegetable slices are made of fruit and vegetable powder. Syrup is directly filled with CO2 to prepare rapidly disintegrating fruit and vegetable tablets, or by adding fillers, disintegrants and other auxiliary materials to prepare rapidly disintegrating fruit and vegetable tablets
