Description
Technical field
The invention belongs to food processing technology field, be specifically related to a kind of preparation method of the Chinese wistaria jasmine tea of delivering vegetables.
Background technology
Deliver vegetables, claim again to send out shape nostoc, a kind of mushroom that belongs to Cyanophyta, it is a kind of natural medicine-food resource being of great rarity, deliver vegetables nutritious, contain the material that carrotene, lutein, chlorophyll, phycocyanin etc. are useful to human body, protein content reaches 20-25%, polyoses content and is 60%, also contains 20 various trace elements and 19 seed amino acids such as zinc, manganese, copper, iodine, and wherein essential amino acid accounts for 40% of total amino acid content in 8.That the polysaccharide that is rich in of delivering vegetables has is hypoglycemic, remove free radical, improve the effects such as immunity, anti-inflammation, is three high crowds' desirable food.
Wistaria pulse family Wistaria, is that a kind of fallen leaves are climbed up by holding on to prehensile liana, and the strong adaptability to weather and soil is more cold-resistant, can water-fastly wet and hungry soil, and happiness light, more resistance to the moon, widely distributed.Chinese wistaria flower is purple or darkviolet, contains more allantoin, allantoic acid, heptacosane, dihydrostigmasterol, volatilization wet goods composition, has the effect of removing toxic substances, antidiarrheal, detumescence, has higher medicinal, edibility.Raising along with scientific and technical, fully utilizes, develops this valuable source, becomes people's common recognition.
Vacuum Freezing & Drying Technology, is that material is frozen into brilliant point below temperature, under vacuum condition, removes the drying means of a kind of applicable heat-sensitive materials of moisture in material by distillation.
Spray drying technology, by mechanism, by the dry material of need, is dispersed into the very thin particulate as mist.Spray-drying process is very fast, can convection drying powdered, and production efficiency is high, and product quality is high, and the contained nutrient loss of material is few.
At present, on market, for the utilization of delivering vegetables and Chinese wistaria is spent, eating or dry and sell greatly mainly with direct culinary art is master.Not only product type is single, and the nutritional labeling that also can make to deliver vegetables in processing procedure in spending with Chinese wistaria runs off in a large number, reduces its edibility.On the market, also not using deliver vegetables and Chinese wistaria flower as a kind of tea-drinking composite formula prepare unique flavor, the product of the evident in efficacy Chinese wistaria jasmine tea of delivering vegetables that is of high nutritive value, keeps healthy occurs.
Summary of the invention
The technical problem to be solved in the present invention is: take delivering vegetables of manually cultivating and fresh Chinese wistaria flower is raw material, adopt Vacuum Freezing & Drying Technology and spray drying technology to prepare a kind of nutritious, unique flavor, the evident in efficacy Chinese wistaria jasmine tea of delivering vegetables of health care, to improve, deliver vegetables and the value of Chinese wistaria flower.
The present invention is for solving the problems of the technologies described above, and the technical scheme adopting is: a kind of preparation method of the Chinese wistaria jasmine tea of delivering vegetables, and preparation process is:
Step 1, get the hair weeds cells kind after activation, be placed in fresh culture, obtain cell suspending liquid, then, under aseptic condition, inoculum concentration by the cell suspending liquid obtaining with culture medium weight 15% is inoculated in the fluid nutrient medium in blake bottle, and it is in the constant temperature biochemical cultivation case of 25 ℃ that blake bottle is placed on to temperature, and in control cabinet, intensity of illumination is 80 mol/m
2/ s, Light To Dark Ratio is 12h: 12h, cultivates 28-32 days;
Step 2, the nutrient solution of delivering vegetables that step 1 is obtained are placed in rotary evaporator to carry out reduction vaporization concentrated, and the temperature while controlling reduced pressure concentration is 40-45 ℃, until the content of solid content reaches 18 ° of Brix;
Step 3, delivering vegetables after step 2 is concentrated are placed in the freezing 2.5 ~ 3h of instant freezer of-26 ~-30 ℃, standby; Meanwhile, choose fresh Chinese wistaria spend clean, drain after, be placed in the freezing 1.5 ~ 2h of instant freezer of-26 ~-30 ℃, standby;
Step 4, by weight, get respectively step 3 and deliver vegetables 1 part after freezing, Chinese wistaria after freezing is spent 3 parts, mixes and is placed in vacuum freeze dryer, and regulating pressure in vacuum freeze dryer is 50Pa, under-20 ℃ ~-25 ℃ temperature conditions, lyophilization 10-20min, afterwards, is placed in the drying box that vacuum is 20 ~ 50 Pa, under 25 ~ 30 ℃ of temperature conditions, parsing-desiccation 10-15h;
Step 5, the material obtaining after step 4 parsing-desiccation is placed in to beater, and add wherein water and pull an oar and process 5-10min, afterwards, adopt the screen cloth that aperture is 1mm to filter the slurries that obtain, get filtrate, and repeat making beating, filtration treatment 2-3 time to filtering the filter residue obtaining, and merge the filtrate that multiple times of filtration obtains, standby;
During described each making beating, the 8-10 that the addition of water is quality of material doubly;
Step 6, the filtrate that step 5 is obtained are placed in homogenizer homogeneous 2-3 time that pressure is 18-22MPa, the Chinese wistaria that obtains delivering vegetables flower cell slurries;
Step 7, the Chinese wistaria flower cell slurries of delivering vegetables are carried out to sterilization treatment, afterwards, transposition is in spray dryer, and the inlet temperature of adjustable spraying drying machine is 170-190 ℃, and intake is 4-6m
3/ min, air draft temperature is 85 ℃, sprays dry, until material moisture≤4% after dry with the feed rate of 1100-1120mL/h;
Step 8, under aseptic condition, the dry thing that step 7 is made packs with tea bag, obtains the finished product Chinese wistaria jasmine tea of delivering vegetables.
Chinese wistaria flower in described step 4, before cleaning, also comprises and adopts the NaclO that mass concentration is 100mg/L
2the step that solution soaks Chinese wistaria flower, and the time of soaking be 0.5-2min.
the invention has the beneficial effects as follows:
1, the preparation method of a kind of Chinese wistaria jasmine tea of delivering vegetables provided by the invention, method is simple to operate, utilization of materials is high, the dry activity that has well retained deliver vegetables nutritional labeling, medicinal ingredient and multiple biology enzyme in spending with fresh Chinese wistaria of vacuum freeze drying and spraying, the particle of finished product tea-drinking material is tiny, nutrient is easy to leach, it is more easily absorbed by the body, and the compositions such as Nostoc flagelliforme Polysaccharides wherein, Chinese wistaria flower dihydrostigmasterol, allantoic acid, aspect the health cares such as adjusting removing toxic substances, detumescence, immunity, Green Tea Extract, effect is remarkable, has very large economic worth.
