Abstract

The present invention relates to a technological method for processing upland wild vegetables and edible fungi, which comprises the steps of picking, classification, selection, loading in a tray, quick freezing at ultralow temperature, vacuum dewatering and drying, sealing, packaging, etc. The water content of processed finished products is between 5% and 15%. When eaten, the products are soaked with water for rehydration. The processing steps of the method scarcely destroy the nutritive substances of the upland wild vegetables and the edible fungi. After being processed by rehydration, the upland wild vegetables and the edible fungi are fresh as normal and have the advantages of refreshing, crisp, fresh, tender and delicious taste, light fragrance and rich nutrient. The purpose of active preservation is achieved. The upland wild vegetables and the edible fungi have the characteristics of simple preparation method, favorable preservation effect, convenient transportation, etc.

Description

The processing method for keeping fresh of hill dish and edible mushroom
Technical field
The present invention relates to a kind of process of processing hill dish and edible mushroom.
Background technology
Now people are aspect the processing of hill dish and edible mushroom, generally all make processes such as can, salt marsh, chemical preservative are fresh-keeping, heat drying, make and contain SO in the product 2, harmful chemical substance such as nitrite and anticorrisive agent.Application number is that the patent application of CN01133653.6 discloses " active preservative liquid processing and eating bacterium and hill dish technology ", application for a patent for invention, the process using salt solution of this application and Jiao Lai metabisulfite solution soak, technology such as bleaching make and contain chemical substances such as chlorine dioxide, activator, dehydro sodium acetate, color stabilizer in hill dish or the edible mushroom.Publication number is that CN1234992A discloses " a kind of keeping green and crisp preservation method of hill dish " application for a patent for invention, the process using of this application is protected green solution and crispness retaining agent, in natural hill dish, added a large amount of chemical substances, made natural hill dish lose natural.Publication number is that CN1559239A discloses " the salt-free dipping method for preserving of hill dish ", it is characterized in that: the hill dish is through cleaning, blanching, pack in the good plastic film bag of oxygen barrier performance while hot, injection contains calcium, copper, the fresh-keeping maceration extract of the isoionic acidity of zinc, the airtight storage of finding time is so that the hill dish is protected is green, it is crisp and fresh-keeping to protect.
Summary of the invention
China's hill dish and edible fungus variety are various, resource is very abundant, local flavor extremely, it is grown in the free of contamination natural environment, it is the green health care food of pure natural, as fiddlehead, little dish, many toothed lady fern, thorn tender bud, Artemisia integrifolia, mushroom, Pleurotus nebrodensis, Hericium erinaceus, agaricus bisporus, coprinus comatus, Asparagus etc., be described as the king in the dish.
Because hill dish and edible mushroom seasonality are very strong, how could guarantee the problem that hill dish and nutrition of edible fungi composition are not destroyed and how the fresh-keeping people of being pay close attention to the most, the objective of the invention is thoroughly to change traditional hill dish and the salt marsh of edible mushroom, antistaling agent, the method for preserving that green keeping agent and traditional heating are air-dry.A kind of Vacuum Freezing ﹠ Drying Technology of utilizing is provided, makes the ordinary people can have any nutriment that does not destroy hill dish and edible mushroom throughout the year, as before fresh after the rehydration, clear and melodious fresh and tender, light fragrance and delicious taste, nutritious hill dish and edible mushroom.Hill dish and the fresh-keeping purpose of edible fungus active have been reached.It is simple that this method has preparation method, and good refreshing effect is the hill dish and the edible fungus fresh-keeping storing technology of non-environmental-pollution.
The invention provides the processing method for keeping fresh of a kind of hill dish and edible mushroom, the key step of its technology is as follows:
(1) gathers and classification:, carry out classification according to grade scale to hill dish and edible mushroom timely collecting;
(2) pluck choosing: will remove the part that root and weeds etc. do not meet quality standard to hill dish and edible mushroom;
(3) balance: will pluck hill dish or the edible mushroom chosen and put in refrigerator tray by every square metre of 8-10 kilogram, refrigerator tray is spread sealed polyethylene plastic, pendulum hill dish or edible mushroom on plastic sheeting;
(4) super low temperature quick frozen: will set refrigerator tray behind hill dish or the edible mushroom and pack in the fast freezing case, refrigerator is opened in airtight back, makes hill dish in the fast freezing case or edible mushroom quick-frozen in 3-4 hour, after temperature be-30 ℃ to-35 ℃, keeps shutdown after 1-3 hour again;
(5) vacuum dehydration drying: hill dish after the quick-frozen or edible mushroom are moved into rapidly in the vacuum dehydration drying box, vavuum pump is opened in airtight back, make vacuum in the vacuum dehydration drying box between 40-60pa, and heat up gradually, temperature rises to 40-60 ℃ in 5-8 hour, kept this temperature again 1-5 hour, the water content that makes hill dish or edible mushroom is shut down between 5%-15%;
(6) pack: hill dish after will dewatering or edible mushroom weighing are packed in the packaging bag, vacuumize packing during sealing, reinstall and are finished product in the carton.
Hill dish and edible mushroom comprise: fiddlehead, little dish, many toothed lady fern, thorn tender bud, Artemisia integrifolia, mushroom, Pleurotus nebrodensis, Hericium erinaceus, agaricus bisporus, coprinus comatus, Asparagus etc.
Advantage of the present invention and good effect are: raw materials used all is pure natural, nutritious hill dish and edible mushroom, nontoxic to human body, has no side effect, often edible, can improve body immunity, increases human nutrition, improves the health, and delays senility.Also health there is the metabolism of regulating body, aid digestion in addition, effect such as improve a poor appetite, men and women, old and young can eat, characteristics such as human absorptivity's height.The inventive method adopts modern Vacuum Freezing ﹠ Drying Technology, does not destroy the effective nutrition in the raw material, and production method is scientific and reasonable.The present invention compares with liquid-state preservation method in the past, do not contain any chemical addition agent, product water content of the present invention is extremely low, so it is not perishable, preservation can reach more than 2 years under the normal temperature state, and present technique has been preserved material effective component and the active and original color of raw material thereof, type to greatest extent.
