Description

Fresh-keeping of vegetables quick-frozen powder
Technical field
The present invention relates to a kind of fresh-keeping of vegetables quick-frozen powder, this fresh-keeping of vegetables quick-frozen powder is applicable to ginger, garlic, onion, the green onion vegetables of food plant collar and other blade face greengrocery.
Background technology
Green onion, ginger and garlic is requisite three kinds of seasoning dishes in the indispensable condiment Chinese kitchen of life, is described as " kitchen Triratna ", can not only seasoning, and allow dish solution raw meat uncharm, flavouring renders palatable, and nutritious, and health is had to benifit.
Ginger belongs to dish root class plant, and ginger meat plumpness, taste are pungent, slightly warm in nature, have unique fragrant fragrance and ginger pungent, are rich in starch.Fat, protein, dietary fiber, mineral matter element.In addition, the composition of formation ginger fragrance mainly contains tens kinds of aromatic substances such as salad oil, ginger aldehyde, zingiberol, zingiberone, lauro lene.Ginger is not only a kind of very important flavouring, and it also has the digestive system function of improvement, suppresses oral bacteria growth, suppress abnormal fermentation in intestines, promote gas discharge and produce refreshing effect to the mind, suppress body endoperoxides deposits yields, anti-ageing, reducing blood lipid, prevent and treat gall stone, the effect such as antitumor.
Garlic, has strong garlic odour, and taste is pungent.Irritant smell, edible or confession seasoning, also can be used as medicine.In garlic, sulfur-containing compound has strong antibacterial and anti-inflammation functions.Garlic can promote the secretion of insulin, reduces blood sugar, prevention diabetes, garlic can prevent the fat deposition in cardiovascular and cerebrovascular, reduces PC, control cardiovascular and cerebrovascular disease, some composition in garlic has similar vitamin E and ascorbic anti-oxidant, anti-aging characteristic.
Green onion; the contained volatile oil component of green onion is mainly sulfur-containing compound, unrighted acid contributes to digestion, anticancer and sterilizing; as shigella dysenteriae etc.; containing. allyl sulphide can be protected stomach; stimulate the secretion of gastric juice; accelerate the digestion of stomach, help and improve a poor appetite, green onion leaf part contains more Multivitamin A, vitamin C.
At present, as the occupation mode of the green onion, ginger and garlic of food flavoring, be generally direct use or be processed into green onion powder, scallion oil, ginger powder, ginger oil, garlic powder, garlic oil.Directly service routine is many, processes unclean.And be processed into powdery, and in technique, requiring to pulverize through hyperthermia drying, its prototroph is destructurized, can not preserve its original taste, and sense of taste reduces greatly.Oils is that high temperature squeezing is extracted, and only has the nutritional labeling of small part to be retained, and most vitamin is all destroyed, and its nutritive value reduces greatly.Moreover as food auxiliary material, the fresh of green onion, ginger and garlic is that kitchen is used key point, and above-mentioned technique can not meet daily life needs completely.
Summary of the invention
In view of above-mentioned present situation, the invention provides a kind of fresh-keeping of vegetables quick-frozen powder, make it have the quick-frozen that can retain again its peculiar flavour easy to use fresh.The fresh powder of this quick-frozen is applicable to the preparation of green onion, ginger, garlic, onion, also can be applied on other similar vegetables simultaneously, and the nutritive value of vegetables, mouthfeel delicate flavour are remained to greatest extent.
Technical solution of the present invention is: a kind of production technology of fresh-keeping of vegetables quick-frozen powder is as follows:
1, the non-harmful fresh vegetables of selected high-quality;
2, clean, clean by high-pressure spraying, clean fresh vegetables surface silt, by skinning machine, the fresh vegetables cleaning up is peeled;
3, once pulverize, the fresh vegetables after decortication is sent into pulverizer and carry out one-level pulverizing;
4, quick-frozen, pulverizes fresh vegetables through one-level and carries out subzero-15 to the cryogenic freezing of-30 ℃ above-mentioned, after freezing 3-4 hour, takes out;
5, separating twice, gets above-mentioned fresh vegetables after freezing, send into ambient temperature in subzero-18 ℃ fresh-keeping adding carry out two grade low-temp powder process break, finally reach 0.1-5 object fresh vegetables powder;
6, packing, vacuum cold bag packing, desinfection chamber temperature maintains subzero-16 to-18 ℃, and humidity remains on 45-60%.
In the present invention, the raw material of related fresh-keeping of vegetables quick-frozen powder, comprises ginger, garlic, onion, the green onion of rhizome plants and blade face class.
Further, the raw material of related fresh-keeping of vegetables quick-frozen powder be select ginger, garlic, onion, green onion any.
The fresh powder of greengrocery quick-frozen of the present invention is to select vegetables rhizome plants and blade face class vegetables through being processed into fresh-keeping quick-frozen powder, facilitates enterprise, family to use.Can make auxiliary material, millet cake, fillings, meat, change traditional use operation, need not lose time again to process at the food materials in early stage, can instantly get.Meanwhile, can solve crude fibre problem by the fresh powder craft of greengrocery quick-frozen vegetables after treatment, the vegetables after processing, crude fibre is ground into powdery, is suitable for the easy to use of the 5--10 of family gram inner wrapping.
