Abstract
The invention belongs to food processing technology field, discloses a kind of processing method of Lipu taro, including step：Raw material selection, cleaning and peeling, finishing, blanching and cooling, quick-frozen, glazing and packaging；The processing method of Lipu taro of the present invention is safe and efficient, remains the original nutriment of Lipu taro, and institutional framework is intact, can be preserved 12 months under 20 DEG C of refrigerated conditions, meet people's demand.
Description
Technical field
The invention belongs to food processing technology field, and in particular to a kind of processing method of Lipu taro.
Background technology
Lipu taro category Araeceae, is called stalwart taro, yam betel, is wild taro originally.Lipu taro head is big, full of nutrition,
Starch-containing 17.5g, protein 2.2g in the taro 100g of Lipu, the calcium being also easily absorbed by the body and certain vitamin.Lipu taro
There is invigorating the spleen, dampness removing, detoxify, disappear and itch, be both make diet dessert, delicacies superior raw material and nourish the body
Nutrient excellent product；Nutriment is rationally transported, skin is moistened, while improve the immunity of body.
Lipu taro carries out artificial cultivation history 400 years existing in Lipu county, special geography and natural bar in Lipu county
Under part, influenced by environment miniclimate, gradually form the local local famous brand product for integrating color, quality outclass it
Taro is produced in its place, and yam betel is produced to Lipu in periphery county very early just the appellation of " Lipu taro " word, Qing Dynasty Kangxu
Guangxi first choice tribute is just listed between year, is paid tribute in the annual end of the year to imperial court.
At present, byproduct obtained by commercially available Lipu taro processing is taro meal, fried taro bar etc. on the market, kind compared with
To be single.The picking time of Lipu taro is in October to December, other seasons few Lipu taros.Therefore, the present invention provides a kind of litchi
The processing method of Pu taro, makes Lipu taro under refrigerated conditions, can preserve 12 months, meets each season people demand.
The content of the invention
The goal of the invention of the present invention is to provide a kind of processing method of Lipu taro, the processing side of Lipu taro of the present invention
Method is safe and efficient, remains the original nutriment of Lipu taro, and institutional framework is intact, can be under -20 DEG C of refrigerated conditions, can
Preserve 12 months, meet people's demand.
In order to realize foregoing invention purpose, the technical solution adopted by the present invention is as follows：
A kind of processing method of Lipu taro, comprises the following steps：
(1) raw material selects：Select the Lipu taro of fresh, disease-free, taro shape subcircular or ellipse；The taro is cross-section
Face diameter 10.0-20.0cm；
(2) cleaning and peeling：The taro chosen first is rinsed with clear water, removes surface silt；Mass fraction is 5-10% again
Aqueous acetic acid soaks 30-60min；Pull out after drying, the sodium bicarbonate aqueous solution for being 1-3% with mass fraction soaks 5-
10min；Clear water rinses, and then moves into skinning machine friction and removes taro skin, and when peeling will be constantly into machine bucket plus with mass fraction
1-2% sodium-chloride water solutions are rinsed well；Taro is soaked with clear water after peeling；
(3) repair：The remaining scurf in taro face is shaved by taro after peeling in (2), then with sharp pocket knife, cuts most taro face yellow

By adopting the above-described technical solution, the beneficial effects of the invention are as follows：
(1) processing method of Lipu taro uses clear water, aqueous acetic acid, sodium bicarbonate aqueous solution and chlorination in the present invention
Sodium water solution four times cleans taro, and the immersion of faintly acid aqueous acetic acid can be taro soft and soggyization, peels easily, reduces wave
Take；Sodium bicarbonate aqueous solution is used for the aqueous acetic acid for neutralizing taro surface, the sodium chloride water of the taro low concentration after peeling
Solution immersion can prevent taro epidermis browning, while prevent the taro of peeling to be contaminated by bacterial.
(2) processing method of Lipu taro will remove the peel taro and carry out blanching in the present invention, retain Lipu taro flavor, pure white
Appearance, will not browning；Conditioner is added during blanching, citric acid can improve taro any surface finish in the conditioner
Degree, propolis extract, cotton extracting solution, ginkgo biloba succi, rutin sophorin are plant antistaling agent, and propolis extract has anti-
Bacterium, anti-inflammatory, suppress the effects such as virus, enhancing antibody mediated immunity；Cotton extraction output of fluid is big, production cost is low, wherein containing Huang
Ketone has anti-inflammatory effect；Ginkgo biloba succi have it is anti-aging, shared with propolis extract, cotton extracting solution, after making blanching
Taro it is non-aging, be not contaminated by bacterial；Rutin sophorin is a kind of nutritional supplement and food antioxidant；Four are used cooperatively
It can ensure that taro keeps freshness, improve the quality of taro processed goods.
(3) in the present invention Lipu taro processing method using fluidized bed type and net belt type dry strongly it is quick-frozen to taro into
Row freezes, fluidized bed type dry strongly it is quick-frozen can freeze taro surface rapidly, keep taro delicate flavour itself not to be destroyed, guipure
Formula dry strongly it is quick-frozen further freeze taro, make taro central temperature be less than -20 DEG C；Glazing, Bao Bing are carried out to taro again
Clothing can prevent taro son from causing drying shrinkage and discoloration in cold storage procedure, improve presentation quality, extend shelf-life.
(4) processing method of Lipu taro is non-fried formula in the present invention, effectively maintains the original mouth of Lipu taro
Sense and flavor；And this quick-frozen taro, can preserve 12 months under -20 DEG C of refrigerated conditions and be unlikely to deteriorate, convenient storage with
Medium-term and long-term transport, increases Lipu taro sales volume, meets farmer and consumer demand.
