Processing method of broken walnut granules in granular walnut milk beverage

Abstract

In order to solve the problems of nutritional ingredient loss and taste improvement caused by an existing walnut milk processing technology, the invention discloses a processing method of broken walnut granules in a granular walnut milk beverage, which sequentially comprises the following steps: (1) drying at low temperature; (2) crushing; (3) removing kernels and peels by an electrostatic method; (4) freeze-drying; (5) crushing; (6) preparing; and (7) packaging. According to the processing method of the crushed walnut granules in the granular walnut milk beverage disclosed by the invention, walnut kernel peels are removed by adopting a method of combining low-temperature drying and crushing with electrostatic adsorption, so that the peeling effect can be ensured, antioxidant components in walnut kernels are protected from being damaged, and meanwhile, rinsing for removing residual alkali liquor in the walnut kernels after peeling is not needed, water and wastewater treatment are saved; the particle size of the walnut milk is smaller than 300 meshes; the absorption rate of protein and amino acid can be increased; the walnut particles smashed to a certain particle size are added into the walnut milk; the taste of the walnut milk beverage is improved on the basis that the quality of the walnut milk is guaranteed; and the walnut milk beverage has popularization value.

Description

technical field

[0001] The invention relates to a walnut deep processing technology, in particular to a processing method for walnut granules in a walnut milk drink. Background technique

[0002] Walnut, also known as walnut and Qiang peach, belongs to the Juglandaceae Juglans plant, and is listed as the world's four major dried fruits together with almonds, cashew nuts and hazelnuts. It is also rich in essential amino acids, linolenic acid, oleic acid and a variety of trace elements, which have the effects of strengthening the stomach, nourishing the blood, moistening the lungs, and nourishing the mind. Nowadays, the development of walnut products in my country is mainly based on walnut kernel, and its products include walnut powder, walnut milk, walnut crisp, collagen walnut and walnut oil series products. Among them, the main nutritional components of walnut kernels are trace elements such as manganese, chromium, selenium, zinc, etc. Multiple antioxidant active ingredie...

Embodiment 1

[0025] Prepare walnut crumbs as follows:

[0026] (1) Low-temperature drying: dry the walnut kernels from which the shell has been removed, and dry at a drying temperature of 40° C. for 6 hours;

[0027] (2) crushing: the above-mentioned walnut kernels after drying are crushed to obtain coarse broken walnut particles;

[0028] (3) Peeling by electrostatic method: Put the coarse walnut particles obtained in (2) into an electrostatic cylinder for peeling, and the shells with poor conductivity are sucked by the roller until they are brushed off; The drum falls ahead of time, and the coarse walnut kernel particles after peeling are collected.

[0029] (4) Freeze-drying: vacuum freeze-drying after pre-freezing in a refrigerator at -80°C, and drying until the moisture content reaches 6%;

[0030] (5) Pulverization: the freeze-dried walnut kernels are pulverized in a pulverizer, the above-mentioned coarse powder is placed in an ultrafine pulverization vibrating mill, and pulverized...
