Description
Technical field
The invention belongs to food industrial technical fields, and the production method of jerusalem artichoke powder is lyophilized more particularly to a kind of selenium-rich.
Background technology
Jerusalem artichoke, also known as " Jerusalem artichoke ", root tuber contain abundant inulin, amino acid, vitamin etc..It is the oligomeric of extraction high-purity
The optimum feed stock of fructose, oligofructose can Bifidobacterium in Effective multiplication human body, reduce blood fat, improve lipid-metabolism, improve people
Body immunity function has been widely used in medicine, healthcare field.However existing production jerusalem artichoke powder all passes through high-temperature process, it is right
The nutrient of jerusalem artichoke powder causes to be lost in processing procedure.Such as:Application No. is 201610188791.4 Chinese invention patents to disclose
A kind of jerusalem artichoke whole powder and its processing method.Its jerusalem artichoke is to utilize high temperature peeling, stripping and slicing, a series of high temperature or the medium temperature such as precook
Aqueous solution in handle jerusalem artichoke, cause production jerusalem artichoke powder in nutrient content reduce.
Selenium is the necessary nutrient of human body, day selenium intake (50-250) μ g that Chinese Soclety of Nutrition is recommended, human body selenium-supply
Mainly by food intake, the average intake per capita in China was in 36 μ g, 500 μ of amount < safe for ingestion g/ days at present, more than 700 μ g/ days
It can cause the poisoning of human body.Jerusalem artichoke powder is the important raw materials for production of health food, but pole is lacked in selenium-rich jerusalem artichoke whole powder market at present
To be rare, main reason is that the plantation research of selenium-rich jerusalem artichoke is seldom.
There are many selenium-supply product on the market at present, and the selenium of selenium-supply product is broadly divided into inorganic selenium (chemical selenium), Biological Selenium (chemistry
Selenium is obtained by microorganism conversion), Selenium in Plants (is got) after higher plant production maturation, these three west are easiest to be absorbed by the body
Be Selenium in Plants, there are potential hazard is maximum be chemical selenium to human body.
Therefore, above-mentioned technical problem how to be overcome to become those skilled in the art's technical problem urgently to be resolved hurrily.
Invention content
Jerusalem artichoke powder nutrient content in order to solve the problems, such as above-mentioned prior art production is low, and this method introduction one kind passes through
The mode of plantation plants organic selenium-rich jerusalem artichoke, and jerusalem artichoke powder is lyophilized in production selenium-rich.
The purpose of the present invention is realized by following methods:
(1) plantation of selenium-rich jerusalem artichoke:1) site preparation, fertilising, 2) sowing, 3) field management:Flower bud is plucked in watering, top dressing, and 4) harvest
The production of jerusalem artichoke powder is lyophilized in jerusalem artichoke, (2) selenium-rich:1) clean jerusalem artichoke, 2) peeling after stripping and slicing, 3) freeze-drying, 4) freeze-drying after be crushed into powder.
Preferably, the site preparation opportunity is September to November, deep plough 30-35cm, per acre organic fertilizer 2500-
3500Kg and selenium-enriched organic fertilizer 500-1500Kg.
Preferably, the selenium-enriched organic fertilizer is sodium nitrite and organic green manure in mass ratio 1:300-1:500 ratio
Example mixing compost forms.
Preferably, the sowing opportunity starts to sow when being spring temperature >=10 DEG C, select stem tuber seed for 20-25g,
45-55Kg, thickness of sowing 40cm*50cm, depth of planting 15-20cm are sowed per acre, after planting in the intermediate 15- of thickness of sowing
At 25cm, ditch spread 800-1000Kg selenium-enriched organic fertilizers per acre.
Preferably, the sowing opportunity starts to sow when being spring temperature >=10 DEG C, select stem tuber seed for 20-25g,
45-55Kg, thickness of sowing 40cm*50cm, depth of planting 15-20cm are sowed per acre, after planting in the intermediate 15- of thickness of sowing
At 25cm, ditch spread 800-1000Kg selenium-enriched organic fertilizers per acre.
Preferably, the water opportunity is the growth seedling stage of jerusalem artichoke, the jointing stage of jerusalem artichoke, the bud stage of jerusalem artichoke, chrysanthemum
The tuber expansion period of taro, watering carry out after growth period applies fertilizer, and the opportunity of top dressing is seedling stage and bud stage, and seedling stage applies house per acre
Animal manure just 400-600Kg, potassium application 15-25Kg, selenium-enriched organic fertilizer 500-800Kg, the opportunity for plucking flower bud are stem tuber to bud stage per acre
Expanding stage.
Preferably, the harvest opportunity is October 1 to October 20.
Preferably, the cleaning is cleaned using drum washing machine, cleaning solution is the sodium hydroxide of 2mol/L, cleaning temperature
Degree is 50-60 DEG C, is rinsed with clear water until pH value becomes neutral after peeling.
Preferably, the size of the stripping and slicing is 10*10mm.
Preferably, the freeze temperature is -55 to -40 DEG C, freeze-drying time is 36-48 hours.
The present invention is by way of plantation, and using the organic transformation of higher plant, manufactured selenium-rich jerusalem artichoke freeze-dried powder is rich in
Plant Organic Selenium is conducive to absorption of human body and reduces food safety risk, and product has filled up the market of selenium-rich jerusalem artichoke freeze-dried whole powder
Blank is conducive to the abundant of healthy food material, wide market.Overall process low-temperature treatment is used in production technology, effectively
Controlled the nutrient losing issue caused by the variation of processing technology.
Specific implementation mode
