Abstract

The present invention discloses whole banana powder producing process, and banana is produced into whole banana powder based its biological characteristic and through adding proper amount of supplementary material. The whole banana powder producing process includes the steps of collecting green banana, washing, instantaneous high temperature deactivation of enzyme, peeling, pulping under the protection of liquid nitrogen, partial enzymolysis, squeezing juice, centrifugal filtering, filtering to eliminate dreg, compounding, extruding and puffing, and crushing, drying to obtain whole banana powder. The production process is superior to available similar production process and has well preservation of the nutritious components and other functional components in banana.

Description

A kind of preparation method of whole powder of banana

Technical field

The present invention relates to a kind of preparation method who utilizes banana and auxiliary material to make whole powder of banana, belong to food processing field.

Background technology

Banana is one of China's four your name's fruit, it contains mineral matter and various vitamins such as rich in protein, lipid, sugar, crude fibre and phosphorus, calcium, iron, potassium, sodium, also contain materials such as a small amount of norepinephrine, serotonin and dihydroxy benzenes ethamine, not only fragrant delicious, can replenish the various nutrition of needed by human body, promote gastrointestinal peristalsis, lubricated stomach, the anti-odd effect that treats constipation.Banana is rich in the material that helps human brain to produce serotonin, can make people's mood become happy and happy, treats melancholia; Banana can stimulate the gastric mucosal cell growth and breeding, produces more mucus, makes ulcer surface not corroded by hydrochloric acid in gastric juice; Banana does not contain cholesterol, and normal food can bring high blood pressure down.Up-to-date scientific experiment shows that the immunocompetence effect of banana is leading in all fruit, can not only increase leucocyte, improves functions of immune system, can also produce to attack paracytic material, impels tumour to dwindle; The resistance to oxidation of bananas juice can be equal to mutually with the catechin of green tea.In addition, banana is rich in potassium ion, eats banana to promote potassium-sodium balance and acid-base balance in the body more, makes neuromuscular keep normal, coordinated heart muscle contractions.Banana belongs to fruit tree in many tropical and subtropical countries, but the four seasons are produced fruit.China's banana has regional advantages, species the advantage and quality and price advantage.In recent years, China's banana production development is swift and violent, and cultivated area reaches 26.5 ten thousand hectares, accounts for 23% of national fruit total cultivated area, and output reaches 605,6 ten thousand tons, and its industry gross output value reaches more than 100 hundred million yuan.In all fruit, though the banana area only ranked fourth the position, because of specific yield the highest (reaching 25.5 tons/hectare), economic benefit is best.Yet banana is storage tolerance not, and is very easily rotten, and it is unsalable to meet prosperous product slightly, loses very seriously, and banana post-harvest loss rate be higher than the average loss rate 25% of China's postharvest fruit and vegetable far away, and developed country only has 5% up to nearly 50% in recent years.Mashed garden incident all took place in these 2 years various places, and the minimum per kilogram procurement price of banana has dropped to below 0.2 yuan.Along with the reduction of China and Association of South-east Asian Nations's agricultural tariff, import increases, and production and marketing contradiction from now on will be more sharp-pointed.In addition, generally there is the noncommodity any of several broadleaf plants of 10-15% not sell on any of several broadleaf plants fringe, calculates that only will there be more than 30 ten thousand tons of noncommodity any of several broadleaf plants wastes or low-priced pin every year in Guangdong Province, lose very serious as bright any of several broadleaf plants.And the noncommodity any of several broadleaf plants is the better raw material of banana deep processing.

Bright banana is processed into various banana that comes from, surpasses the food of banana, not only make delicious food and the function that to share banana away from the consumer in the place of production, also can improve the added value of banana.Help farmer richness and enrich functional food market, have huge social benefit and economic benefit.Seen in the market banana converted products kind and quantity seldom, main cause is that the processing technology of banana requires than other garden stuff processing its unique technique difficult point to be arranged.Remove banana and be rich in pectin substance, squeeze the juice and be difficult to the screenings separation, outside the high dry difficulty of sugar content, content of material such as banana tannin are higher, be easy to produce bad change of local flavor and nutritive loss under brown stain and the high temperature in the process, cause the commodity performance to be difficult to fatal reasons such as assurance, seriously restricted the development of banana processing industry.In recent years pot foods such as fried banana chip have also been developed in market, but the product mouthfeel is poor, and former nutritional labeling loss is serious, produces carcinogen suspicion in addition, so the market acceptance is not high.

Summary of the invention

The objective of the invention is to disclose a kind of preparation method of whole powder of banana, it is the biological characteristics according to banana, and appropriate amount of auxiliary materials is processed into whole powder of banana in addition.

The present invention finishes by the following steps preparation:

Green banana → cleanings → TRANSIENT HIGH TEMPERATURE go out enzyme → decortication → liquid nitrogen protect look making beating → part enzymolysis → spiral shell for sleeping in and squeeze the juice → centrifugal filtration → filter residue → allotment → extruding sprays quick-fried → pulverizing → drying → whole powder of banana.
