Abstract
The invention relates to a preparation method of dried day lilies. The preparation method comprises the following steps of (1) picking day lilies; (2) pretreating the picked day lilies; (3) cooking the pretreated day lilies; (4) twisting the day lilies treated in the step (3), after twisting is completed, performing sealing at room temperature, and performing static fermentation for 12-18h; and (5) performing drying. According to the preparation method disclosed by the invention, water-soluble glucan and a reduction type glutathione aqueous solution are used for performing pretreatment, and then high-temperature rapid-scalding and cooking are performed, so that technical obstacles are well overcome; the water-soluble glucan can form a layer of a protective film on the surfaces of the day lilies, and can generate substance cross-linking with the histocyte of the day lilies, so that the tenacity of the day lilies in subsequent treatment can be enhanced, the day lilies are not liable to crush when being rolled, and the quality of the day lilies is good; and the reduction type glutathione is also uniformly distributed in the protective film, the reduction type glutathione and the protective film are in synergistic reaction to avoid polyphenol oxidase oxidation, after practice, people find that the reduction type glutathione and the protective film can efficiently prevent the day lilies from changing color during draining and steam rapid-scalding, and the tenacity of the day lilies after rapid-scalding and cooking is still high.
Description
Technical field
The present invention relates to a kind of preparation method of day lily dry vegetalbe, belongs to fruits and vegetables technical field.
Background technology
The flower of day lily has functions that stomach invigorating, logical breast, enriches blood, and women breast-feeding their children galactosis deficiency person eats it, can play
The effect that logical breast is stimulated the secretion of milk；Root has functions that diuresis, detumescence, can be used to treat edema, difficult urination；Leaf plays the role of to calm the nerves, energy
The diseases such as treatment neurasthenia, dysphoria and insomnia, body void edema.Traditionally the root of various tawny daylilies is used as medicine regardless of and only using as edible
The bud of chrysanthemum tawny daylily.
Day lily has preferable brain tonic, and senile-resistant efficacy is that this material is in body because it contains abundant lecithin
The constituent of many cells, particularly brain cell, plays an important role to strengthening and improving cerebral function, while can remove dynamic
Deposit in arteries and veins, there is special efficacy to symptoms such as absent minded, failure of memory, cerebral arteries emphraxis, and old friends are referred to as
For " brain tonic dish ".
Show according to another research, day lily can significantly reduce the content of serum cholesterol, be conducive to the rehabilitation of hyperpietic,
Can be used as the health-care vegetable of hyperpietic.The also growth of the inhibition cancer cell of energy containing active ingredient, abundant thick fibre in day lily
Dimension can promote the excretion defecated, therefore can be used as the food of preventing and treating enteron aisle carcinoma.
At present, on market day lily product is more based on health product, and day lily is fresh and tender perishable, and 2-3 is placed at normal temperatures
My god, either freshness, local flavor or quality all can be substantially reduced, and distinctive edibility almost be lost less than one week, to storage
Transport, sale, processing bring great difficulty, it has not been convenient to preserve and carry, it is impossible to meet the market demand.
The content of the invention
It is an object of the invention to solve the deficiencies in the prior art, there is provided a kind of preparation method of day lily dry vegetalbe, the party
The day lily dry vegetalbe of method processing can keep the delicious taste of day lily and the sweet-smelling of day lily, and color and luster is good, long shelf-life.Nutrition
It is abundant, it is of high nutritive value.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of preparation method of day lily dry vegetalbe, the preparation method comprises the steps：
（1）Day lily is plucked：The day lily that fresh complete nothing is obstructed always is plucked, is placed in where shady and cool ventilation and is stored for future use；
（2）Day lily pre-processes：Step（1）The day lily of rinsed clean is soaked in pretreating agent and pre-processes 30-45min, institute
It is that the SG of mass fraction 1-3% and the reduced glutathione of mass fraction 0.5-0.8% mix to state pretreating agent
The aqueous solution, 5-8 DEG C of pretreatment temperature, pretreating agent pH5.0-5.5, day lily weight in wet base is 1 with the volume ratio of pretreating agent:3-5；
（3）Day lily shortening：Step（2）Pretreated day lily drains and divide after pretreating agent in pallet, thickness 3-5cm,
It is subsequently placed in steam box and steams 60-90s in 90-95 DEG C, is then quickly cooled to room temperature；Then dried using centrifugal drier；
（4）By step（3）Day lily after process is kneaded, and 10-15min is kneaded every time, is kneaded 4-6 time, after the completion of kneading
It is sealed in normal temperature static fermentation 12-18h；
（5）It is drying：Step（4）Semi-finished product Jing roasting machines after process are stir-fried, dried, and obtain day lily finished product.
The maximum technology barrier of its deep processing of day lily is to maintain original color and luster and maintains the problem of mouthfeel, causes discoloration
（Brown stain, nutrition organoleptic quality can be caused in day lily process）Main cause be polyphenol oxidase oxidizing brown stain, this
Bright employing SG and the reduced glutathione aqueous solution are pre-processed, and then high-temperature steam speed cooks system by scalding, very well
Solve this technology barrier, SG can form layer protecting film on day lily surface, and with day lily tissue
Material crosslinking, can improve its tenacity between cell in subsequent treatment, should not crush when kneading, the quality better of day lily, the guarantor
Reduced glutathione is also evenly distributed with cuticula, with diaphragm synergy polyphenol oxidase oxydasis is avoided, sent out in practice
It is existing, draining and can changed colour with the extremely efficient day lily that prevents during steam speed is scalded, speed is cooked the day lily tenacity after system by scalding and is remained unchanged.
Preferably, step（2）Described in pretreatment for mass fraction 1.5-2.5% SG and mass fraction
The reduced glutathione mixed aqueous solution of 0.6-0.7%, 6 DEG C of pretreatment temperature, pretreating agent pH5.2, day lily weight in wet base with it is pre-
The volume ratio of inorganic agent is 1:5, when the pretreating agent is configured, SG solution is first configured, add formula ratio
Reduced glutathione, stir, with citric acid adjust pH value.Find in practice, SG solution is first matched somebody with somebody
Put, the oxygen in solution can be received between the glucan of macromolecular, add reduced glutathione, glutathione can be avoided
It is oxidized in advance in course of dissolution, improves its antioxidant effect.
Preferably, step（2）Described in pretreatment for mass fraction 2% SG and mass fraction 0.65%
Reduced glutathione mixed aqueous solution.
Preferably, step（5）The temperature of middle roasting machine frying is 120-130 DEG C, time 12-20min.
The invention has the beneficial effects as follows：The maximum technology barrier of its deep processing of day lily is to maintain original color and luster and maintenance
The problem of mouthfeel, causes discoloration（Brown stain, nutrition organoleptic quality can be caused in day lily process）Main cause be polyphenol
Oxydasis brown stain, the present invention is pre-processed using SG and the reduced glutathione aqueous solution, Ran Hougao
Warm steam speed cooks system by scalding, is well understood that this technology barrier of having determined, and SG can form one layer of guarantor on day lily surface
Cuticula, and the material crosslinking between day lily histocyte, can improve its tenacity in subsequent treatment, should not crush when kneading,
The quality better of day lily, is also evenly distributed with reduced glutathione in the diaphragm, with diaphragm synergy polyphenol is avoided
Oxydasis, in practice find, drain and steam speed scald in can be changed colour with the extremely efficient day lily that prevents, speed cook by scalding system after
Day lily tenacity remain unchanged.
