Total chestnut peptide nourishment and preparation method thereof

Abstract

The invention relates to a total chestnut peptide nourishment and a preparation method of the total chestnut peptide nourishment. Polypeptide, short peptide, oligopeptide and the like can be generated from the nutritional ingredients inside the chestnut to be directly assimilated by a human body. The total chestnut peptide nourishment provided by the invention comprises 1-60wt% of peptide, linolenic acid, linoleic acid, DHA (Dehydroacetic Acid), vitamin, glucose and the like. The preparation method of the total chestnut peptide nourishment comprises the following steps of: soaking chestnut kernel in a VC (Vitamin C) solution or a citric acid solution for color protection, adding water into the soaked chestnut kernel for grinding and pulping to obtain a chestnut pulp, carrying out chestnut starch alpha treatment on the mixed pulp at the temperature of 130-135 DEG C and under the pressure of 6-8Pa, grinding to 120-300 meshes, saccharifying the chestnut starch inside the pulp after the sterilization, regulating the pH value to 3.5-5.5 after the enzyme deactivation, adding acid proteinase and lipase into the pH regulated solution, standing still at constant temperature, carrying out biochemical degradation condensation to obtain the raw total chestnut peptide solution, and further preparing a total chestnut peptide powder, a total chestnut peptide capsule, a total chestnut peptide tablet, a total chestnut peptide oral liquid or a total chestnut peptide functional sports beverage.

Description

technical field [0001] The invention relates to nutritional products, which is a whole chestnut peptide nutritional product produced by using the principle of bioengineering technology and a preparation method thereof. Background technique [0002] Chestnut is a perennial deciduous fruit tree, also known as Dali and Kuili. Chestnut fruit is rich in nutrients, containing 51-60% starch, 5.7-10.7% protein, 2-7.4% fat, 15 mg calcium, 1.2 mg iron, 1.32 mg zinc, and 11.45 vitamin E per 100 grams. mg, 0.15 mg of riboflavin, 2.5 mg of vitamin C, crude fiber, carotene, vitamins A, B, C, calcium, phosphorus, potassium and other minerals, the nutrients available for human absorption and utilization are as high as 98%. Chestnut belongs to the category of nuts, and its starch content is very high. The carbohydrates of dry chestnuts reach 77%, which is equivalent to 75% of grains; fresh chestnuts also have as much as 40%, which is 2.4 times that of potatoes. Chestnuts are rich in vitam...

Problems solved by technology

[0003] Although chestnut has high medicinal value and is rich in nutrients, it is difficult to digest and absorb because it contains a lot of starch and sugar, especially for diabetics, eating too much will affect the stability of blood sugar

At present, people only rough-process chestnuts, such as: sugar-fried chestnuts, canned chestnuts, chestnut soup, chestnut sauce and other products. Technical means not only imprison people to fully tap and utilize the rich nutrients of chestnuts, but also seriously hinder the enthusiasm of chestnut farmers to plant chestnuts, so that the added value and unique nutritional value of chestnuts have not been well improved
