Description

A kind of processing method of dehydrated onion

Technical field

The present invention relates to a kind of onion goods, specifically is a kind of processing method of dehydrated onion.

Background technology

Onion is nutritious, according to surveying and determination, about bright onion bulb water content 88 grams of per 100 grams, protein 1～1.8 gram; Fat 0.3～0.5 gram, carbohydrate 5-8 gram, crude fibre 0.5 gram, heat 130 kilojoules; 12 milligrams of calcium, 46 milligrams in phosphorus, 0.6 milligram of iron, 14 milligrams of vitamin Cs; 0.5 milligram of niacin, 0.05 milligram in riboflavin, 0.08 milligram of thiamine, trailing plants L is plain 1.2 milligrams recklessly.Also contain caffeic acid, sinapic acid, cinnamic acid, citrate, polysaccharide and several amino acids.Be rich in allicin, mercaptan, trisulfide etc. in the volatile oil.Bud, pollen, flower pesticide etc. all contain carrotene.Onion has the effect of expelling cold, eliminating, hypoglycemic, reducing blood lipid, treatment diabetes and prevention of osteoporosis.But because its smell is unique, some people can't use.

Summary of the invention

The present invention provides a kind of processing method of dehydrated onion, is about to onion and is processed into dehydrated onion, can not only keep the nutrition of onion, can also partly remove onion flavor, instant, also convenient the storage and transportation.

The present invention realizes with following technical scheme: a kind of processing method of dehydrated onion is that raw material is peelled off Lao Pi with onion with the onion, wash clean, and stripping and slicing is peeled off in flakes, and oven dry is processed, and concrete technological process is:

Select materials → raw material processing → stripping and slicing peels off in flakes → immersion → baking → packing → finished product;

Described selecting materials is that the fresh onion bulb that choosing is not rotted is raw material, and be subsequent use;

It is that onion bulb is removed Lao Pi, goes into clear water and clean that described raw material is handled;

Described section is that onion bulb is cut into the 4-6 piece, peels off then in flakes;

Described immersion is the onion sheet to be soaked the part of removing in the onion in 10-15 minute with clear water cause tear composition cycloalliin, and drop removes moisture, dries then;

Described dehydration is that the onion sheet is placed in drying room or the baking oven, and baking is 8 hours～10 hours under 50 ℃～70 ℃ temperature, and making onion sheet moisture content is 5.5%-7%;

Packing is under drying, aseptic condition, the onion sheet to be packed, and is finished product.

The invention has the beneficial effects as follows: the dehydrated onion that utilizes the inventive method to produce, as long as can restore with emerge in worm water, special odor is little, taste is better than fresh onion, the convenient storage.

The specific embodiment

Embodiment
