Problems solved by technology

However, due to the large amount of fat and coconut protein contained in coconut meat and coconut milk are very sensitive to heat treatment, it is easier to produce protein coagulation and precipitation and oil-water separation, which will affect the taste of coconut powder
In addition, during the production process, substanc

Abstract

The invention discloses a manufacture method of natural coconut powder. The manufacture method comprises the following steps that 1) coconut juice and coconut meat are mixed and pulped at 70 to 90 DEG C and are stored for 20 to 30 minutes; 2) the pulp liquid is regulated until the temperature is 40 to 50 DEG C, the pH is 3.0 to 4.0, pepsase, cellulose and pectinase are added, and the hydrolysis and the blanching are carried out; 3) the filtering is carried out, the filtrate is taken, a centrifugal machine is used for separation, oil phases are removed, and water phases are collected; 4) the water phases are subjected to low-temperature vacuum concentration to obtain concentrated liquid with the solid content being 15 percent to 20 percent; 5) modified starch or maltodextrin is added, the pH value is regulated to be 5.0 to 6.0, and mixed liquid is obtained; and 6) the mixed liquid is subjected to high-temperature sterilization, spray drying and granulation, and the natural coconut powder is obtained. The manufacture method has the advantages that the process is simple, the cost is low, the problems of easy protein precipitation generation, oil and water separation, high fiber content, product oxidation and the like in the coconut processing process can be effectively solved, the obtained coconut powder has good instant solubility, and the original color, fragrance and smell and the nutritional ingredients of the coconut are fully maintained.

Description

technical field [0001] The invention relates to a method for preparing fruit powder, in particular to a method for preparing natural coconut powder. Background technique [0002] Coconut has high nutritional value. Traditional Chinese medicine believes that coconut meat is sweet in taste and flat in nature, and has the effects of nourishing the spleen and stomach, killing insects and eliminating malnutrition; coconut milk is sweet in taste, warm in nature, and has the functions of promoting body fluid and diuresis. Modern medical research shows that coconut meat contains protein and carbohydrates; coconut oil contains sugar and vitamin B 1 , Vitamin B 2 , vitamin C, etc.; coconut milk contains more nutrients, such as fructose, glucose, sucrose, protein, fat, vitamin B, vitamin C, calcium, phosphorus, iron and other trace elements and minerals. It can be seen that coconut is a good product for both medicine and food. Coconut meat and coconut milk are the main processing c...
