Description
Technical field
The present invention relates to food processing technology field, a kind of method preparing the instant dry powder of Fructus psidii guajavae immaturus.
Background technology
Fructus psidii guajavae immaturus (PsidiumguajavaL), has another name called chicken and vows fruit, pulls out son, Myrtaceae (Myrtaeeae), Psidium
(Psidium), evergreen perennial shrub plant.Fructus psidii guajavae immaturus meat thickness matter is crisp, fresh and sweet tasty and refreshing, has the fragranced of uniqueness, rich in
Vitamin C (Vc), polyphenol, riboflavin, soluble protein etc., liked by consumers in general deeply.It both can be eaten raw, can process again
Become the product such as fruit juice or powdery, also there is medicinal and health-care effect, such as blood sugar lowering, prevention diabetes, antioxidation etc..Fresh kind
Pomegranate fruit skin is thin and tender, easily damages, and it is serious to adopt rear low water, and hardness declines rapidly, and therefore shelf-life is shorter, is weak to storage
Fortune, after general a couple of days, quality and flavor is just varied from, and commodity value is substantially reduced.
The exploitation of Fructus psidii guajavae immaturus health food: be with Fructus psidii guajavae immaturus as raw material, can be processed into health promoting product, such as: kind stone
Pomegranate canned food, guava beverage, Fructus psidii guajavae immaturus wine, Fructus psidii guajavae immaturus dried fruits, Fructus psidii guajavae immaturus preserved fruit, guava jelly etc..Prior art is to a kind stone
The most freeze-dried for fresh Fructus psidii guajavae immaturus, disintegrating process are simply prepared dry powder by the deep processing of pomegranate, to facilitate storage and transport,
But the effective ingredient in Fructus psidii guajavae immaturus is still in plant tissue cell's wall, and does not dissolve or extract so that this kind of stone
Pomegranate powder is not easy to absorb, and the effect after eating is not ideal enough.Stirring need to be also needed to make with the water of temperature higher temperature when therefore reconstituting
It fully dissolves, and brings many inconvenience to user；On the other hand be exactly the product after processing, original nutritional labeling and natural
Flavor loss is serious.Instant powder is that a kind of convenience, pure natural property, compound nutritional of collecting easily is stored in the health care food of one
Product, instant-drink, adapt to current people's high efficiency, allegro living needs, but being not yet related to Fructus psidii guajavae immaturus makes speed at present
The report of molten powder.
Summary of the invention
The present invention is directed to the problem that Fructus psidii guajavae immaturus deep processing exists, it is provided that one can keep Fructus psidii guajavae immaturus nutritional labeling and natural
Local flavor, again can be with instant-drink, the preparation method of Portable belt, easily the preservation instant dry powder of Fructus psidii guajavae immaturus.
In order to realize object above, the present invention is to be achieved through the following technical solutions:
A kind of method preparing the instant dry powder of Fructus psidii guajavae immaturus, comprises the following steps:
(1) plucking fresh Fructus psidii guajavae immaturus to clean, the colour-keeping liquid formed with sodium citrate and EDTA-2Na soaks 2-3h, then by color fixative
Fructus psidii guajavae immaturus after process uses juice extractor to squeeze the juice, and obtains guava raw juice；
(2) in guava raw juice, add the mixed enzyme that Fructus psidii guajavae immaturus weight ratio is 1.0-1.5% and carry out enzymolysis 2-3h, described mixing
Enzyme is made up of beta galactosidase and cellulase；
(3) by the juice after enzymolysis vacuum be 0.10-0.12Mpa, temperature be 70-80 DEG C to carry out being concentrated into material aqueous
Amount is 15-20%, obtains concentrated solution；
(4) by concentrated solution pre-freeze 2-3h at temperature is-25 DEG C～-35 DEG C, it is then placed in vacuum freeze drier and carries out freezing
Being dried, control vacuum is 0.10-0.12MPa, temperature is dried 6-8h at-45 DEG C～-55 DEG C, and obtaining water content is 5-7%'s
Xeraphium；
(5) by xeraphium through ultraviolet-sterilization, packaging, the instant dry powder of Fructus psidii guajavae immaturus is obtained.
Preferably, in the above colour-keeping liquid, the weight concentration of sodium citrate is 0.6-0.8%, EDTA-2Na weight concentration
For 0.4-0.6%.
Preferably, the weight ratio of the above beta galactosidase and cellulase is 1:2-4.
Preferably, the temperature of the above enzyme digestion reaction is 35-45 DEG C.
Preferably, above-described ultraviolet-sterilization is with the ultraviolet lamp sterilization 30-60min that power is 100-150W.
Compared with prior art, advantages of the present invention and having the beneficial effect that
1, the instant dry powder of Fructus psidii guajavae immaturus that the inventive method prepares through steps such as color retention, enzymolysis, vacuum lyophilizations, can
Keep Fructus psidii guajavae immaturus nutritional labeling and natural flavour mountaineous, have again cold water instant-drink, Portable belt, easily preserve, the advantage such as easy to use,
And then the deep processed product kind of abundant Fructus psidii guajavae immaturus, it is beneficial to promote the development of Fructus psidii guajavae immaturus industrialization, improves the economic well-being of workers and staff of orchard worker.
2, this method processes through complex enzyme hydrolysis, makes soluble component in raw material fully discharge and be dissolved out, thus subtracts
The loss of few nutritional labeling, improves the nutritive value of product.
3, this method uses colour-keeping liquid process can suppress Fructus psidii guajavae immaturus, in processing, storage, brown stain easily occurs, and keeps
The color and luster of raw material is colour-keeping liquid stable performance used, safety, good to human body non-hazardous, effect of color protection.
4, the inventive method uses vacuum freezing to be dried Fructus psidii guajavae immaturus powder, can avoid various nutrition to greatest extent
Composition and the loss in the course of processing of the functional activity composition, improve the quality of product.
5, the inventive method has that technique is simple, it is low to consume energy, production efficiency is high, low cost and other advantages, it is adaptable to industrialization
Produce.
