Clear kiwifruit whole fruit instant powder and preparation method thereof

Abstract

The invention relates to a preparation method of clear kiwifruit whole fruit instant powder, which sequentially comprises the following steps: raw material pretreatment, kiwifruit pulping, kiwifruit pulp composite enzyme enzymolysis at normal temperature, centrifugation, fruit juice homogenization, fruit juice sterilization, fruit juice drying and kiwifruit whole fruit powder crushing; the methodfully utilizes the whole kiwi fruit and ensures that the whole kiwi fruit powder has good quick solubility and clarity; the processing procedures of enzymolysis, drying and the like of the kiwifruit with a long time are all carried out at a lower temperature, so that the good flavor of the product is effectively ensured; compared with vacuum freeze drying, a vacuum belt type drying mode is used toimprove the processing speed of the product, so that the product has better economic efficiency and better flavor and color protection of the product; the method also has better microorganism controleffect, the product can be used in various types of solid beverages and liquid beverages, the microorganism of the system does not exceed the national standard, and the requirements of industrial production are met.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a clarified kiwi whole fruit instant powder and a preparation method thereof. Background technique [0002] Chinese kiwifruit, aliases: carambola, sheep peach, etc. The fruit is yellowish brown, nearly spherical, oval, and the pulp is green.

Problems solved by technology

In addition, kiwi fruit has also been developed for whole fruit, but it is mainly used for the development and use of preparation products, which cannot meet the requirements of liquid beverages for taste, instant solubility and clarity. This is the current development status of kiwi fruit powder.

[0004] At present, the preparation method of kiwi fruit powder mainly has the following disadvantages: the drying temperature is too high and the juice enzymolysis temperature is high, which leads to browning of kiwi fruit juice and poor flavor, and the utilization of whole kiwi fruit has poor instant solubility and insufficient clarity. , poor microbial control, etc.
