Abstract
The invention discloses a drying method of pitaya flowers. The drying method comprises the following steps: collecting fresh pitaya flowers or flower buds, and trimming; then putting the trimmed fresh pitaya flowers or flower buds into steam and pre-treating; then putting the pitaya flowers or flower buds into cold water and carrying out water cooling treatment; after draining, carrying out microwave drying and cooling; then carrying out softening treatment to raise the moisture content again; and finally, packaging in vacuum. According to the technical scheme disclosed by the invention, the pitaya flowers are treated by a preparation method of dehydrating, carrying out microwave treatment, and supplementing water and softening, so that the integrity of flower petals and the flower buds of the pitaya flowers is kept, and the prepared pitaya flowers have good color and luster, rich aroma and keep complete nutrients; and meanwhile, the pitaya flowers can be stored and used for a long period, so that the popularization of edible and medical values of the pitaya flowers is realized.
Description
Technical field
The present invention relates to food processing technology field, particularly relate to a kind of Pitaya Flower dry-making method of dried.
Background technology
Hylocereus undatus (HylocereusundatusBritt.&Rose) originates in Central America Brazil, Mexico's torrid zone desert area, and perennial Cactaceae, triangular prism belong to, fruit tree in many tropical and subtropical countries.Catchment fruit, flowers, vegetable, health care, medicine of Hylocereus undatus is integrated, and has significantly high economic worth.Pitaya Flower corolla diameter about 25 centimetres, total length about 45 centimetres, single flower weighs 600～800 grams and is referred to as " Flos Caryophylli king ", and when beautiful Flos Caryophylli bursts forth, fragrance assails the nostrils.The yield of Pitaya Flower is high, and under not affecting the premise that Hylocereus undatus is born fruit, average yield per mu still cocoa reaches more than 4000 jin.Pitaya Flower is not only beautiful, it is also possible to edible, delicious and have distinguished health-care effect.Its pollen anthocyanidin content Gao Feng, and there is high nutrition, low in calories, low fat, rich in the feature such as vitamin and aminoacid.Whole flower can be eaten raw or process, and eats clear and melodious lubrication raw, fragrant and sweet delicious.Frying fragrant and sweet clear and melodious, boil soup and sample fresh and sweet, chaffy dish is superfine product especially.Flower is put in boiling water and brew or boil several minutes, dried in the air cool with crystal sugar and drunk again, more aromatic than chrysanthemum scented tea.Hylocereus undatus dry flower pot LAOJI, DAGU have been south China famous dishes, immensely popular.Hylocereus undatus dried flower tea cough-relieving is relieved inflammation or internal heat, and improving eyesight, blood pressure lowering effectiveness are significant.Hylocereus undatus has effect of improving eyesight, pathogenic fire reducing, has prophylaxis of hypertension effect.In unique mucus that Hylocereus undatus flower and stem possess because osmotic pressure is extremely low, containing the significant nutritional substance of a large amount of drug effects and therapeutic substance, its flower can relieve inflammation or internal heat, lung moistening, cough-relieving, pulmonary tuberculosis, bronchitis, Neck lymphatic tuberculosis are had auxiliary therapeutic action.Therefore, the Development volue of Pitaya Flower and market prospect are very big.
Microwave be a kind of frequency at 300MHz～300GMHz, the periodically variable electromagnetic wave of its direction and size catch cropping at any time.This electromagnetic wave, not by Metal absorption and conduction, can only be reflected；The insulant such as glass, pottery, plastics can be penetrated without consumed energy, it is possible to absorbed and then be converted into the marked feature of heat energy by polar molecule (such as hydrone, protein, fat, nucleic acid, carbohydrate etc.).The principle of microwave drying is that material directly acts on microwave, and the polar molecule (hydrone etc.) in material absorbs microwave, and changes original molecular structure under the effect of microwave, and presenting direction arranges；Polar molecule carries out polar movement with the change of external electromagnetic field, and with the speed (microwave of 915MHz under polar molecule movement velocity for 9.15 hundred million times/second) identical with microwave frequency carry out frictional impact produce heat energy, make material from inside at short notice temperature raise rapidly reach heating and ripening effect.It is short that microwave has the time, speed fast, uniform and complete, K cryogenic treatment, keep nutrition, energy-conserving and environment-protective, safe and harmless, save cost, improve the advantages such as efficiency, have been widely used in fields such as food processings.But this area there is no the prior art utilizing microwave technology to prepare Pitaya Flower.
Summary of the invention
It is an object of the invention to provide a kind of Pitaya Flower dry-making method of dried, thus realizing the long term storage of Pitaya Flower so that it is edible and medical value is developed.
Technical scheme is as follows:
The Pitaya Flower dry-making method of dried of the present invention comprises the following steps: gather fresh Pitaya Flower or petal finishing is placed in steam pretreatment, place into and cold water carries out water-cooled process, microwave drying and cooling is carried out after dewatering, then the process that eases back is carried out, make its water content go up, finally carry out vacuum packaging.
Wherein, pretreatment be by finishing after Pitaya Flower be placed on steam treatment 0.5min～1min under the temperature conditions of 100 DEG C～120 DEG C.Water-cooled processes the Pitaya Flower being steam treatment to be crossed and places 5s～10s in cold water.Microwave drying be by dewatering after HUOLONG flower be contained in carrying disk after put in drying baker, microwave drying 10min～20min when 540W～720W, stirring 2 times～4 times.Ease back is that the Pitaya Flower that dry cooling is good is positioned over 2h～3h in the environment that air humidity is 75%～85% so that it is water content goes back up to 16%～18%.
Due in technical scheme, Pitaya Flower anhydrates through first, microwave treatment, the method for making that moisturizing eases back again, thus remaining the integrity of the petal of Pitaya Flower, petal, make that the Pitaya Flower color and luster made is good, thick flavor, nutrition retain complete, are beneficial to simultaneously and preserve for a long time and take, it is achieved that the popularization of the edible medical value of Pitaya Flower.
