Abstract
The invention discloses a production process for dehydrated barley shoot powder and belongs to the deep processing technology field of agricultural products. The production process comprises the following procedures: (1) the pretreatment of the raw materials, (2) the combined drying of vacuum freezing and hot wind, (3) crushing, (3) sterilization and packaging. In the production process, the technology of vacuum freezing drying and hot air drying is utilized, so the production cost is decreased and the product quality is improved.
Description
Technical field
The invention belongs to technical field of agricultural product process, relate in particular to the production technology that the hot air combined seasoning of a kind of vacuum refrigeration prepares dewatered barley seedling powder.
Background technology
Barley seedling contains rich in protein, vitamin, mineral matter and high-quality dietary fiber, has nutrition and health care value.Modern study shows: the protein in the barley seedling not only content is abundant, best in quality, is easy to digest and assimilate, and constitutes amino acid A wide selection of colours and designs, the reasonable mixture ratio of protein; Barley seedling is rich in vitamin C, vitamin E, Cobastab
2Deng multivitamin, and Miao Lvsu, carotene carotene content are abundant; Micro elements needed by human content height such as macroelement such as potassium, calcium, iron and zinc, selenium in the barley seedling, alternative fruit and vegetable is satisfied human body required mineral matter every day.In addition, barley seedling is rich in that superoxide dismutase (SOD), catalase (CAT), aspartate transaminase (AAT) etc. are multiple to have an enzyme anti-oxidant, that delay senility.
Dry technology is the important component part in the food processing technology field.The normal both at home and abroad at present drying means that adopts has heated-air drying, vacuum freeze drying, fried dehydration etc.The dehydration fruit and vegetable using of China nearly 90% adopts the heated-air drying method to process.Heated-air drying has that equipment is simple, easy to operate, small investment, low cost and other advantages, but because the baking temperature height, especially the heat-sensitive substance loss is serious for nutriment in the raw material; The rate of water loss inequality easily causes product shrinkage, surface sclerosis, and the product rehydration is poor.Vacuum freeze-drying method can keep the color and the nutritive value of product preferably, and the product rehydration is good, but vacuum freeze exist floor space big, environment and operating technology are required high, disposable shortcoming such as have high input, can't make this method widespread usage in the not high processing of farm products of added value of product.Though the vacuum frying dehydration can realize the dehydration to raw material at a lower temperature, product color is good, the nutriment loss is few, owing to dewater rapidly at vacuum frying initial stage raw material, causes product distortion, surface sclerosis, simultaneously product oil content height.As seen, adopt single dry technology, be difficult to reach take into account and improve product quality and the purpose that reduces production costs.For reducing production costs, the production of dewatered barley seedling powder adopts the heated-air drying method to process mostly in the prior art, and especially the heat-sensitive substance loss is serious for nutriment, and the rate of water loss inequality causes product shrinkage, surface sclerosis, and the product rehydration is poor.
Summary of the invention
Purpose of the present invention provides a kind of production technology of dewatered barley seedling powder, and integrated utilization vacuum freeze drying and heated-air drying technology have improved product quality again when reducing production costs.
Technical scheme of the present invention is summarized as follows: the production technology of dewatered barley seedling powder comprises the following steps:
(1) pretreatment of raw material: choose the fresh barley seedling of plant height 20～35cm, selected, removal of impurities, clean, drain away the water, segment is (behind the segment length 4～5cm), in-18～-20 ℃ of cryogenic freezing 3～4h;
(2) drying: the barley seedling after freezing adopts vacuum refrigeration-hot air combined drying means, in vacuum is that 90～120Pa, baffle temperature are to dewater to wet basis moisture content 20～30% in 60～80 ℃ the vacuum freeze drier, takes out to place 45～65 ℃ of hot air driers to dewater to wet basis moisture content below 5%;
(3) pulverize: the barley seedling after the dehydration is crushed to 180～200 orders through the cyclone type pulverizer;
(4) sterilization, packing: dewatered barley seedling powder is behind microwave sterilization, and vacuum packaging makes barley seedling powder.
Integrated utilization vacuum freeze drying of the present invention and heated-air drying technology, at the dry initial stage (constant rate drying period), adopt Vacuum Freezing ﹠ Drying Technology, Free water in the raw material is distilled rapidly, material is dewatered in a large number, do not change the organoleptic quality and the nutritional quality of raw material, and equipment is simple, less investment; At the later stage of drying (falling rate drying period), transfer heated-air drying to by freeze drying, because the Free water in the raw material has distilled fully, this moment, the wet basis moisture content had only 20～30% before dry, the quality of raw material and structure are fixing, thus the later stage during heated-air drying material can not produce shrinkage, distortion, surperficial hardening phenomenon.Heat-sensitive substance content such as vitamin C, SOD, CAT and AAT are abundant in the dewatered barley seedling powder that the hot air combined dry technology of employing vacuum refrigeration is made.
The present invention is a raw material with fresh barley seedling, through preliminary treatment, the hot air combined drying of vacuum refrigeration, pulverizing, sterilization and packaging process, make that color and luster is emerald green, quality homogeneous, local flavor is pure, rehydration good, the nutrition and health care function is outstanding dewatered barley seedling.Compared with prior art, the hot air combined seasoning of the vacuum refrigeration of the present invention production technology for preparing dewatered barley seedling powder has the following advantages:
(1) the present invention is according to the feature and the dehydration characteristic thereof of barley seedling, integrated utilization Vacuum Freezing ﹠ Drying Technology and heated-air drying technology, take into account the purpose that improves product quality and reduce production costs, Vacuum Freezing ﹠ Drying Technology is used widely in processing of farm products;
(2) dewatered barley seedling produced of the present invention has not only kept Miao Lvsu in the fresh barley seedling, vitamin, mineral matter etc., and can reduce the loss of heat-sensitive substances such as vitamin C in the dewatered barley seedling powder, SOD, CAT and AAT, improve the nutritive value and the health care of product;
(3) the dewatered barley seedling powder color and luster of the present invention's production is emerald green, local flavor is pure, rehydration good, the nutrition and health care function outstanding, can be used as the raw material of food and health products.
