Description
Technical field
The present invention relates to the crisp preparation method of a kind of selenium-rich green tea shelled melon seed, belong to tealeaves and technical field of food deep processing.
Background technology
Sunflower seeds is the leisure food that liked by people, also is rich in protein, grease, starch and various trace elements in the sunflower seeds, so sunflower seeds also is a kind of healthy functions food.The traditional Chinese medical science thinks that the shelled melon seed property in the sunflower seeds is sweet cold, the effect that has moistening lung to put down liver, controls bloody flux, passes through carbuncle purulence.The Along with people's growth in the living standard, in great demand as the sunflower seeds of leisure food, whenever celebrating happy festival time or general holiday, all kinds of local flavor melon seeds are favored by the people especially, offer relatives and friends to this, have become the common custom in the many places of China.
The shelled melon seed shortcake that utilizes the shelled melon seed in the sunflower seeds to process is pure because of its local flavor, and nutrition is unique, is a kind of practicality, general leisure food.The shelled melon seed sold in the market is crisp to be added flour and white sugar etc. mostly and processes, and its local flavor and kind are comparatively single, and it is also comparatively rare to have the shelled melon seed shortcake type that strong tea fragrant breeze distinguishes the flavor of.
Selenium is the necessary nutrient of human body, and selenium can be protected cardiac muscle, prevents and treats the generation of multiple diseases such as Keshan disease, Kaschin-Beck disease, hepatopathy and cancer, if the selenium intake deficiency will have a strong impact on the healthy of people.Tea tree is the stronger plant of a kind of natural selenium-rich ability, and contained selenium is the organic selenium to the human body beneficial mostly in the selenium-enriched tea leaf, and Chang Yinfu selenium tea has become one of important channel of mending selenium.Green tea is the traditional natural health beverage of China.Contain the multiple functional component useful such as Polyphenols, Tea Pigment, tea polysaccharide and theanine in the green tea, have BA widely such as anti-oxidant and cancer-resisting health.Super fine tea powder is the ultra-fine tea powder of pure natural that the modern superfine communication technique of a kind of process is produced; It has kept unique color and luster and nutrition, the pharmaceutical component of tealeaves to greatest extent; Characteristics such as very strong surface adsorption power, affinity and solid perfume (or spice) property are arranged; Digested and assimilated by stomach easily, also capable of direct drinking or make an addition in the varieties of food items.
In recent years, the crisp market demand of tea system food is increasing, and people are also become clear day by day to the requirement of its taste and health-care effect.And the crisp processing enterprise of the shelled melon seed based food of China new product development ability is lower at present, and designs and varieties are less, and its model change cycle is also longer relatively.So improve the crisp production technology of shelled melon seed, the research and development newtype has seemed very necessary with the crisp product of new local flavor shelled melon seed.
Summary of the invention
The purpose of this invention is to provide the crisp production method of a kind of selenium-rich green tea shelled melon seed; Shelled melon seed so that this method makes is crisp; Both having had the crisp-fried flavor of shelled melon seed and strong tea fragrant breeze flavor, and also be rich in the selenium element of needed by human body simultaneously, is a kind of nutrition leisure food of unique flavor.
Technical scheme of the present invention is following:
A kind of selenium-rich green tea shelled melon seed is crisp, and its characteristics are that raw material is by following weight portion proportioning: shelled melon seed 40~60 g, maltose 50~60 g, glucose syrup 40~60 g, white granulated sugar 40~50 g, super fine tea powder 40~50 g, refined salt 30~50 g, cream 10~20 g; Said super fine tea powder is to be that the selenium-rich green tea of 0.35~0.45 μ g/g is that to obtain the following particle size range of 200 orders through ultramicro grinding processing granularity be the super fine tea powder below 200 orders to raw material with selenium content.
As preferably, its raw material is by following weight portion proportioning: shelled melon seed 50 g, maltose 50 g, glucose syrup 50 g, white granulated sugar 50 g, super fine tea powder 50 g, refined salt 50 g, cream 20 g.
Above-mentioned shelled melon seed is a polly seed nucleole, and said polly seed nucleole cleans the back with the oven dry again after 12~24 hours of selenium-rich green tea water extract infuse; The tealeaves of said selenium-rich green tea water and the proportioning of water are 0.25~0.30 g/ml; The Se content of said selenium-rich green tea is 0.35~0.45 μ g/g.
The preparation method that selenium-rich green tea shelled melon seed of the present invention is crisp comprises following steps:
(1) preparation of super fine tea powder
With the selenium-rich green tea is raw material, with drying tea leaves after ultramicro grinding processing obtains particle size range is the super fine tea powder below 200 orders;
(2) preliminary treatment of shelled melon seed
A, take by weighing a certain amount of selenium-rich green tea tealeaves earlier and tighten with cord with gauze parcel back; Polly seed nucleole after cleaning is put into pot together with the tealeaves of gauze parcel, is that 0.25~0.30 g/ml ratio adds distilled water in 100~140 ℃ of temperature boiling 10~20 min in tea-water proportion; After treating that the tealeaves water-cooled but, leave standstill under the room temperature after 12~24 hours and dry polly seed nucleole;
B, the polly seed nucleole that processing of step A is crossed are poured in the pot, add vegetable oil in polly seed nucleole and vegetable oil weight portion ratio 30~50:1, and at 100~140 ℃ of frying 20~30 min of temperature, it is cool cold that said polly seed nucleole fries the back;
(3) maltose, glucose syrup, white granulated sugar boils
According to the above ratio maltose, glucose syrup and white granulated sugar are put into pot together, in pot, add to heat behind a little clear water and boil, endure, turn heating-up temperature down so that liquid glucose is in not curdled appearance to the liquid glucose boiling;
(4) the crisp moulding of selenium-rich green tea shelled melon seed
A, according to the above ratio, with super fine tea powder with fry good polly seed nucleole and pour into rapidly and stir in the pot, after waiting to stir it is transferred on the chopping block that scribbles very thin one deck vegetable oil, before liquid glucose solidifies with the floating polly seed nucleole that compresses of dipper;
B, the sunflower seeds that will just solidify are used the cutter cutting block forming, in the crisp packaging bag of behind cooling and ultraviolet-sterilization, packing into of the shelled melon seed of moulding, carry out vacuum packaging.
Used tealeaves is natural selenium-rich green tea among the pre-treatment step A of said polly seed nucleole, and the proportioning of tealeaves and water is 0.25~0.30 g/ml in the said tea, and the said infuse time is 24~36 hours.
Compared with present technology, beneficial effect of the present invention is embodied in:
1, the crisp development of selenium-rich green tea shelled melon seed of the present invention's production is on the basis of traditional handicraft; In conjunction with modern manufacturing process; The local flavor and the color and luster of nutritious shelled melon seed and tealeaves are combined, produce the peculiar flavour that both contains tealeaves, the tea system casual health food of the nutritional quality with shelled melon seed is arranged; Satisfy consumer's diversified demand, have good social and be worth and economic worth the crisp based food of shelled melon seed.
2, the inventive method technology is simple, easy implements; The crisp product tea smell of made shelled melon seed is strong; Good mouthfeel has characteristics nutritious, that appetizing helps food, also is rich in the selenium element of needed by human body simultaneously; Meet people in modern and pursue the health diet mode of nutrition, health care, convenience and pure natural, be suitable for men and women, old and young and taste for a long time.
