Description

Rich selenium tea and production technology thereof

Technical field

The present invention relates to food processing field, particularly a kind of rich selenium tea and production technology thereof.

Background technology

Selenium is one of essential trace element of the mankind.Whole world science mechanism, health organization are unanimously generally acknowledged at present, and micro elements needed by human free from controversy has eight kinds: selenium, iron, manganese, copper, cobalt, zinc, molybdenum, iodine.

At present known human diseases relevant to scarce selenium have kind more than 40, comprise cancer, brain cardiovascular disease, diabetes, hepatopathy, thyroid hormone is unbalance etc.

The World Health Organization in 1973 confirms that human essential elements is: iron, selenium, copper, zinc, iodine etc.The normal operation that human body wants to sustain life must be absorbed enough selenium from food.According to statistics, the whole world has more than 40 countries and regions to belong to scarce selenium area.China is a Ge Que selenium big country, investigates according to geologist: the area of China 72% belongs to and lacks selenium area, and the natural food Se contents such as grain are lower; The big and medium-sized cities such as North China, northeast, northwest all belong to and lack selenium area, some areas of 22 provinces and cities of China, and approximately 700,000,000 people live in low selenium area.Scientist measures: some disease, particularly tumour, hypertension, endocrine metabolism disease, diabetes, atonic constipation are all relevant with scarce selenium.The rich selenium tea of China is mainly produced by district rich in selenium at present, and because inorganic selenium content in its soil is high, tea tree transforms Organic Selenium by absorption, organic selenium content in tealeaves is increased, thereby make rich selenium tea.But this rich selenium tea itself because absorb transforming degree difference, organic selenium content is unstable inequality also, has height to have low, cost is larger, thereby can not be popularized.Therefore, China begin one's study again explore additive method make rich selenium tea.Fail again to produce a desired effect by the way that adds selenium in soil in recent years.Having again now many products is by the dilution of Organic Selenium biological agent, sprays sprinkling amount on tea tree blade face, such way still can not ensure the organic selenium content of product, neither absorb by biology self growth, so its biological Organic Selenium utilization rate is not high, nutrition and health care poor effect.

Summary of the invention

The present invention has researched and developed a kind of rich selenium tea and production technology thereof, and object is: produce a kind of organic selenium content high, Organic Selenium bioavailability is high, the nutrient health-care tea product that do not contain any residual inorganic selenium composition and have no side effect.

This technical scheme:

A kind of rich selenium tea, is characterized in that, comprises following material: selenium-enriched edible mushroom powder, tea powder, maltodextrin and fruits and vegetables powder.

Described fruits and vegetables powder does not comprise apple powder and hawthorn powder.

The quality proportioning of described selenium-enriched edible mushroom powder, tea powder, maltodextrin and fruits and vegetables powder is: 5:3:1:1.

A kind of rich selenium tea technological process comprises: batching, mixing, oven dry, sterilizing, slaking, grind and pack.

A kind of rich selenium tea technique, is characterized in that, comprises the steps:

1) by selenium-enriched edible mushroom powder, tea powder, maltodextrin and fruits and vegetables powder according to quality proportioning be: 5:3:1:1 carries out proportioning;

2), the good raw material of said ratio is uniformly mixed by mixing plant, the microwave production line of sending into 20KW carries out microwave drying and sterilization process;

3), by medicinal Ultra-Micro Grinding Equipment to sterilizing after raw material grind, fineness reaches 120 orders;

4), carry out independent quantitative by fully automatic powder packaging facilities and pack out the rich selenium tea of solid beverage.

In described step 3), micro-wave temperature is set in 85-90 degree, the time: 3-5 minute.

The invention has the beneficial effects as follows:

Technique of the present invention compared with prior art tool has the following advantages: cultivate the technology maturation of selenium-enriched edible mushroom powder raw material, raw material sources are extensive, and preparation technology is simple, and easily support is held.We select the flat mushroom that poly-selenium ability is the strongest, output is the highest edible mushroom, the process of mushroom growth self can absorb selenium element and other trace element and other nutrition in the middle of culture medium, can in its body, carry out biochemical process, after evenly mixing with raw material with other again, obtain rich selenium tea (solid beverage), and guarantee the rich content of Organic Selenium simultaneously, and meet selenium tolerance limit in national selenium-enriched food, thereby bring into play its diseases prevention, disease-resistant effect, improve the immunologic function of human body.Meanwhile, use Organic Selenium and inorganic selenium more superior.

Detailed description of the invention

Below in conjunction with embodiment, the present invention is described further.

Embodiment mono-:

1, the production of selenium-enriched edible mushroom powder:

Raw material selenium-enriched edible mushroom powder is the important composition that ensures the organic selenium content of this product.With pure water be 250-300PPM by sodium selenite dissolved dilution to selenium content, be evenly sprayed at above degermed maize core powder, airing repeatedly, full and uniform dry to make obtain the culture medium of rich selenium.Rich seleno culture medium is according to specification raw materials for production mushroom.After the collection of raw material mushroom, remove by despecking and addle, go bad and the mushroom body of dying of illness, clear water rinses, finishing, pick up broken mushroom and shank, through the slaking of microwave production line, dry, sterilization, dry mushroom body obtains selenium-enriched edible mushroom powder again after 120 orders of Ultra-Micro Grinding Equipment separate.

Embodiment bis-:

Rich selenium tea (solid beverage) is taking selenium-enriched edible mushroom powder, tea powder, maltodextrin and fruits and vegetables powder (except apple powder, hawthorn powder) as raw material, through batching, mixing, oven dry, sterilizing, slaking, grind, the technique such as packaging refines the directly Instant Drinks that form.

1, the quality proportioning of selenium-enriched edible mushroom powder, tea powder, maltodextrin and fruits and vegetables powder is: 5:3:1:1.

The proportioning of getting 100 grams of raw materials is: 50 grams, selenium-enriched edible mushroom powder, 30 grams, tea powder, 10 grams of maltodextrins, 10 grams, fruits and vegetables powder.
