Method for synchronously preparing two banana powders by utilizing bananas

Abstract

The invention discloses a method for synchronously preparing two banana powders by utilizing bananas, which belongs to the technical field of deep processing of fruits. The method comprises the steps of: taking fresh bananas as a raw material; obtaining a banana pulp zymolyte through peeling and slicing, protecting color and blanching, beating, applying pectase and performing enzymatic liquefaction of alpha-amylase; obtaining two parts, namely a fruit juice supernatant and a fruit paste precipitate through centrifugal separation; performing vacuum concentration on the fruit juice supernatant part, then adding an additive into the concentrated fruit juice supernatant part for blending, and performing spray drying to obtain instant banana fruit juice powder; and drying the fruit paste precipitate part by adopting a free-drying method, and then crushing the dried fruit paste precipitate part to obtain banana powder rich in fiber. The method has the advantages of having a scientific and reasonable process, simple and convenient operation, low consumption of a drying additive, low drying load and energy-saving effect, allowing for obtaining two banana powder products, and improving the utilization rate of edible parts of the bananas.

Description

technical field [0001] The invention discloses a method for simultaneously preparing two kinds of banana powders from bananas, which belongs to the technical field of fruit deep processing, and in particular relates to a method for preparing banana powders. Background technique [0002] Banana is one of tropical and subtropical "four major fruits" (lychee, pineapple, coconut, banana), and is also the most widely cultivated tropical fruit in the world. my country's banana production has always been among the top in the world. However, banana fruit is not easy to keep fresh, not resistant to storage and transportation, and the postpartum loss is serious. In recent years, the post-harvest loss rate of bananas in my country has been as high as nearly 50%, which is much higher than the average loss rate of 25% in my country and 5% in developed countries. Therefore, the deep processing of bananas is of great significance to my country's banana industry. The current banana deep-...

Problems solved by technology

[0004] However, because bananas are rich in pectin, sugars, tannins and various enzymes, they are easily browned during processing, resulting in deterioration of color, nutrition and flavor, which seriously affects the quality of products. It exists in large quantities, causing difficulties in processing techniques such as material transfer and moisture removal

Therefore, there are certain defects in the existing banana powder processing technology, such as the high cost of freeze-drying, and the poor solubility of the obtained banana powder; and the instant banana powder prepared by the spray drying process utilizes the soluble part and discards the insoluble part , the utilization rate of banana is low
