Abstract
The invention provides a method for preparing honeydew dendrobium flower tea. The honeydew dendrobium stem flower tea is prepared by utilizing the vacuum impregnating and freezing drying technology, which is improved on the basis of the conventional sun shining, baking, heating and drying process, the vacuum impregnation and vacuum accelerated freeze-drying are finished under an closed environment, so that the medicinal properties of dendrobium flower can be fully exerted, the active ingredients of the dendrobium flower can be protected maximally during the preparation process of the honeydew dendrobium flower tea, and the pollution of microorganisms to the product can be avoided. The bee honey and the dendrobium flower are combined, so that the natural preservative, namely, bee honey is dissolved into the flower, the prepared dendrobium flower tea is easy to preserve and store, the whole shape of the flower is well kept, and the made flower tea has faint scent, sweet taste. The honeydew dendrobium flower tea is convenient to carry, easy to store; and the flower is flat and dry.
Description
Technical field
The present invention relates to a kind of preparation method of jasmine tea, particularly relate to a kind of preparation method of honeydew stem of noble dendrobium jasmine tea, belong to health food processing technique field.
Background technology
The modern lives that the mode major part exists that operating pressure is big, dinner party is many, tobacco and wine are immoderate, intemperance in sexual life, do not have enough sleep, and takes in many, amount of exercise problem such as less, thus deficiency of Yin person see many, so modern's health focuses on enriching yin.Modern medicine and traditional Chinese medicine pharmacological research prove, the stem of noble dendrobium contains that human bodies such as dendrobium polysaccharide, dendrobine and amino acid and calcium, magnesium, zinc, iron, manganese, selenium, copper, chromium, nickel are metabolic must trace element, is building up health, is improving human immunological competence, anti-ageing, enriching yin qi-restoratives, promoting production of body fluid and nourishing the lung, spleen benefiting and stimulating the appetite, nourishes the liver to improve visual acuity, the skin moisten beauty treatment, suppressing tumour, tonifying five zang organs consumptive disease, improves aspects such as diabetic symptom and treatment atrophic gastritis positive effect is arranged.
The stem of noble dendrobium is except dry product, bright product effect are extensively approved by people, and the medical value of stem of noble dendrobium flower never has fine developing in fact.The stem of noble dendrobium itself is well nourishing Yin and moistening lung except keeping for stem of noble dendrobium flower, nourishing the stomach to improve the production of body fluid, the heat-clearing that makes eye bright, strengthen the curative effects such as immunity, anti-ageing, treatment breathing problem, diabetes, chronic hepatitis, chronic gastritis, its obvious effect is Xie Yu, can make people's mood optimistic after taking, can fine alleviation city crowd's stress big, feel more tired, symptoms such as mood is irritated, depression.
But the stem of noble dendrobium jasmine tea that traditional method of rubbing, ted, toasting is made, the nutritional labeling loss is many, the color and luster dimness, mouthfeel changes, and flower is crisp, and petal is damaged easily, and overall appearance changes, and value falls sharply.
Summary of the invention
The invention provides a kind of property of medicine that promptly can give full play to stem of noble dendrobium flower, can in preparation process, protect the preparation method of stem of noble dendrobium flower active ingredient again to greatest extent.This preparation method adopts the multifunctional vacuum impregnator with honey, evenly, thoroughly be penetrated in each trickle pore and space of stem of noble dendrobium flower fast,, utilize vacuum impregnation can reduce contacting of oxonium ion in the flower of the stem of noble dendrobium in the preparation process and the air, reduce the activity of polyphenol oxidase, keep the stem of noble dendrobium to spend original local flavor and shape largely.
By freeze drying, keep the sharp freezing state again, help keeping some biological sample activity in freezing whole process.Freeze drying is preserved preferably to the institutional framework and the mode of appearance of stem of noble dendrobium flower, there is not surperficial sclerosis problem in flower, and inner formation porous is spongy, and have excellent rehydration and a nerve, can recover dry preceding shape at short notice,, therefore suppressed the heat-sensitive substance generation effectively under very low temperature because dry run is to carry out, preserved the active material in the raw material preferably, and original color and luster of flower.
Utilizing vacuum impregnation, freeze drying is technological improvement to traditional Exposure to Sunlight, oven dry heat drying technology, adopt honey and combining that the stem of noble dendrobium is spent, natural anticorrisive agent honey is dissolved in the flower, the easier keeping of stem of noble dendrobium jasmine tea, the storage of preparation, the shaping that flower is remained intact, sweet, the delicious taste of jasmine tea fragrant that bubbles out.
The invention has the beneficial effects as follows, adopt vacuum impregnation and freeze drying processing stem of noble dendrobium flower, vacuum, heating, cooling, drying all machine under enclosed environment, have avoided the pollution of microorganism to product.Use vacuum impregnation to combine with freeze drying than tens times of traditional fabrication time shortenings, it is simple in structure, easy to operate, product surface is smooth, the flower lovely luster, the petal pliability is good, be not easy breakage, keep original color, shape and nutritional labeling, avoided the Exposure to Sunlight of employing conventional method, baking to make to greatest extent product nutrition and functional component are destroyed.For market provides a kind of preservation easy to carry, easy, the stem of noble dendrobium jasmine tea product that flower is smooth and dry.
The specific embodiment
A kind of stem of noble dendrobium flower of preparation method's picking of raw material high-quality of honeydew stem of noble dendrobium jasmine tea, selected decontamination, vacuum impregnation, pre-freeze is prepared, and accelerated freeze-drying technology is made, and its preparation method comprises following steps:
1. selected raw material: pass through pluck the stem of noble dendrobium flower that comes selected, select the flower of intact wound, remove the foreign material of blade and so on, be spread out in the 1～2d that progressively dries in the shade on the indoor bamboo mat, when flower moisture descends, hand pinch the petal softness not cracky just can pack in the vacuum impregnation machine.
2. vacuum impregnation: stem of noble dendrobium flower is packed in the vacuum impregnation jar, start the machine and vacuumize 3～15min, vacuum reaches 0.08～0.10MPa, the water content that sucks weight such as flower then is 20%～24% honey, vacuumizes 10～40min again, and vacuum is preserved 0.10～0.12MPa, in interlayer, feed simultaneously steam, make honey be heated to 50 ℃～70 ℃, when vacuum drop in the jar to normal pressure, emit honey flower drained, dry.
3. pre-freeze is prepared: open cold lyophilizer refrigerant compression device carries out precooling to refrigerating chamber, when freezer temperature reaches-15 ℃, the flower of vacuum impregnation is placed on to send into freeze drying on the charge pallet indoor, temperature is controlled at-20 ℃～-30 ℃ and is frozen into solid-state, vacuum remains 66～80Pa, cooling time 1.5～2h.
4. accelerated freeze-drying: freezing stem of noble dendrobium flower is in sublimation condition, improves the temperature of shelf under the charge pallet, and progressively heating-up temperature is elevated to 30 ℃～35 ℃, continues 8～10h, takes out dry stem of noble dendrobium flower, adopts the aluminum-plastic composite membrane vacuum packaging.
