Technology for preparing instant powder of banana fruit juice

Abstract

The invention discloses a preparation process of instant banana juice powder, which comprises the following steps: 1. After peeling and cutting ripe bananas into sections, they are placed in a microwave oven for microwave enzyme-inactivation treatment; 2. After the enzyme-inactivated banana slices are beaten, pulp is added Carry out enzymatic hydrolysis with enzymes, then separate by centrifuge, and filter to obtain banana juice; 3. Add embedding agent to the obtained banana juice, then stir, homogenize, and spray dry. The invention uses microwave treatment to passivate or inactivate the polyphenol oxidase that causes enzymatic browning of bananas, thereby slowing down the oxidation of phenolic substances, reducing the generation of melanin, and avoiding browning during processing; the obtained bananas The fruit juice powder microcapsule embedding rate reaches 94.4%, and its solubility is good; the color of the product is light yellow, maintaining the strong flavor of banana.

Description

technical field [0001] The invention relates to a preparation process of instant banana juice powder. Background technique [0002] Banana is one of the famous fruits. It is sweet and delicious, suitable for all ages. The fruit is rich in carbohydrates, crude fiber, pectin, calcium, phosphorus, iron and other mineral nutrients and multivitamins, with high nutritional value. Banana resources are abundant in southern my country, and the deep processing and utilization of banana resources is basically blank, mainly fresh food; in the existing processing technology, bananas are made into powder by freezing and vacuum low-temperature drying methods to dry the banana meat, Grinding into powder, due to the expensive equipment required, low output and high energy consumption, this method is difficult to be widely used. Because bananas are rich in pectin, tannins, sugars and various enzymes, it is not only difficult to store and transport, but also easily browns during processing, re...

Banana resources are abundant in southern my country, and the deep processing and utilization of banana resources is basically blank, mainly fresh food; in the existing processing technology, bananas are made into powder by freezing and vacuum low-temperature drying methods to dry the banana meat, Grinding into powder, due to the expensive equipment required, low output and high energy consumption, this method is difficult to be widely used

Because bananas are rich in pectin, tannins, sugars and various enzymes, it is not only difficult to store and transport, but also easily browns during processing, resulting in deterioration of color, nutrition and flavor, which seriously affects the quality of products; At the same time, a large amount of pectin and sugars exist, which makes it difficult to process and utilize
