Embodiment 1

[0028] Example 1, see figure 1 :

[0029] The present invention provides a kind of method adopting closed-loop dehumidification-heat pump technology to make banana chips, adopting closed-loop dehumidification-heat pump drying technology, comprising the following steps:

[0030] 1) Raw material selection: select banana fruits with basically the same size and maturity and without any defects in appearance;

[0031] 2) Cleaning and peeling: wash off the surface dirt of the raw bananas, peel off the banana peels manually, and put them in the color protection solution for temporary storage;

[0032] 3) Slicing: Cut off the two ends of the cleaned banana pulp, and then cut it into circular banana slices with a thickness of 0.3cm;

[0033] 4) Color protection: Clean and peel the fresh pineapple fruit without pests and diseases, put it in a juicer, add 4 times the quality of drinking water, squeeze the juice with a squeezer, and then use a centrifuge to centrifuge at a speed of 1000...

Abstract

The invention provides a method for making banana slices by a closed-loop dehumidification-heat pump technology. Through the closed-loop dehumidification-heat pump drying technology, the banana slices are prepared through raw material selection, cleaning and peeling, slicing, color protection, deastringency, drying and packaging. Through the closed-loop dehumidification-heat pump drying technology and pineapple juice-based color protection, the problem of browning in the process of banana processing is solved, the original banana tissue morphology, smell, good sensory evaluation and nutritional ingredients are kept maximally, product moisture content is reduced, the inner cell structure is complete, quality is good, the color is bright and is golden yellow, a thick banana fragrance is obtained and the flat surface is obtained. The method is simple, has high production efficiency and low energy consumption and satisfies clean production requirements such as energy saving, emission reduction and efficiency increasing.

Description

technical field [0001] The invention relates to the technical field of food production, in particular to a method for producing banana slices by adopting a closed-loop dehumidification-heat pump technology. Background technique [0002] Banana, known as Ganjiao in ancient times, is a plant of the Musa family of Musaceae, also referring to its fruit. It is widely cultivated and eaten in tropical areas. The fruit is long and ribbed, with yellow skin and white flesh. The meat is soft and waxy, sweet and delicious. Bananas are high in nutrition and low in calories. Every 100 grams of pulp contains 1.2 grams of protein, 0.5 grams of fat, 19.5 grams of carbohydrates, 0.9 grams of crude fiber, 9 mg of calcium, 31 mg of phosphorus, and 0.6 mg of iron. It also contains carotene and thiamine. Vitamins, niacin, vitamin C, vitamin E and rich trace elements such as potassium. In traditional Chinese medicine, bananas have the effects of clearing heat, detoxifying, nourishing yin and mois...
