Method for utilizing overspeed freezing to manufacture banana pulp

Abstract

The invention discloses a method for utilizing overspeed freezing to manufacture banana pulp. Ripe bananas serve as raw materials, the banana pulp is made by peel removal, line removal, color protection, pulping and homogenizing and the like, and overspeed-freezing banana pulp is obtained by vacuum packaging, precooling and overspeed freezing and is finally refrigerated at 20 DEG C below zero. The method is a quick-freezing low-temperature fresh-keeping method and is characterized that the freezing speed is quick, ice crystals are small, the preserving time of the quickly-frozen banana pulp is long, original flavor quality of the bananas can be preserved, heat in the bananas and energy for supporting various chemical activities are reduced, part of free water of cells is frozen simultaneously, water activity is lowered, nutrition of the bananas is preserved to the largest extent simultaneously without aids of any anticorrosive agent or addition agent, and the problem of browning in the banana processing process is solved thoroughly by optimizing a banana pulp preparation process. The method is efficient, advanced and simple and convenient to operate, and provides a novel effective way for processing of agricultural products.

Description

technical field [0001] The invention relates to a method for preparing banana pulp, in particular to a method for preparing banana pulp by ultra-fast freezing using ripe bananas as raw materials, and belongs to the field of agricultural product processing. Background technique [0002] Banana is one of the four major fruits in the world, and it is also a tropical characteristic fruit. It not only has high yield and good cultivation benefits, but also has rich nutrition and multiple functions, so it has become the fruit with the largest consumption and trade volume of fresh fruit in the world. Banana fruit is rich in protein, fat, carbohydrates, crude fiber, pectin, potassium, selenium, calcium, phosphorus, iron and other trace elements and various vitamins, and it is low in sodium and cholesterol-free. Beauty, lowering blood fat, lowering blood pressure, lowering blood sugar functions, so bananas are known as the "sacred fruit on earth" that integrates nutrition and health c...

Problems solved by technology

At present, there are four major technical problems in the processing of banana pulp to varying degrees, namely pulp browning, muddy erosion, nutrient loss and aromatic substance escape. Among them, browning and flavor preservation are the main problems. The traditional heat sterilization method makes the flavor rapidly Deterioration has seriously affected the quality of banana pulp. These problems have affected the quality and consumption purchasing power of banana pulp to varying degrees. At present, there is no ideal banana pulp processing method.
