Description

A kind of preparation method of kiwifruit peel ferment
Technical field
The present invention relates to field of food, and in particular to a kind of preparation method of Mi kiwifruit peel ferment.
Background technique
Kiwi berry (scientific name: Actinidia chinensis Planch), also referred to as Chinese grooseberry, fruit shape are generally ellipticity, Early stage appearance is in green and brown color, is in bronzing after mature, and epidermis covers dense villus, edible, is inside pulp bright green With the seed of row's black or red.Kiwi berry removes organic containing actinidine, proteolytic enzyme, tannin pectin and carbohydrate etc. Outside 17 kinds of amino acid of the microelements such as object and calcium, potassium, selenium, zinc, germanium and needed by human body, vitamin C also rich in, Portugal Grape acid, fructose, citric acid, malic acid, fat.In recent years with the development of fruit processing industry, a large amount of Kiwi berry processing waste shapes At, these wastes again mainly based on kiwifruit peel, up to the 20%~30% of raw material, new environomental pollution source is formed. In order to solve food processing industry problem of environmental pollution, waste is made a silk purse out of a sow's ear, urgent need establishes a kind of process conditions for Kiwi berry Skin slag utilizes again.
Ferment, an etymology is in Japan, namely what is often called " enzyme ".Before liberation on the textbook in China be also enzyme be referred to as " ferment " , present China Taiwan is still referred to as " ferment ".However present market is by the health food referred to as " ferment " of favor It is to make raw material with all kinds of plants, the fermented food made by lactic acid bacteria or saccharomycetes to make fermentation.
The ferment product of domestic listing is more at present, mostly using fruit as base stock, add some additives or its The features such as his substance, is obtained by easy fermentation technique, and kiwifruit peel has villus more, complicated component, and moisture is few uses Common ferment technique is difficult to for kiwifruit peel being effectively treated, it is difficult to which realization effectively utilizes again.
Summary of the invention

Preferably, the dried yeast powder activity is to be not less than 5000 containing active dry yeasr in every gram of dried yeast powder.
Preferably, the first generation culture medium the preparation method is as follows:
(1) wheat is cleaned with water, be soaked in water 6-12h, be placed in the germination of 10-20 DEG C of shady place, upper cover gauze, it is daily it is early, in, Late water drenching is primary, when malt is extended to 1-3 times of wheat length, it is allowed to stop germination, drying is ground into malt flour.(2) will Add the 3-6 times of water measured in malt flour, keep the temperature 3-6h in 65 DEG C of water-baths, filter, jamaicin is added in filtrate, jamaicin is added Amount is 0.001-0.005 times of filtrate quality.
(3) the sugared concentration in above-mentioned solution is detected with Baume hydrometer, is diluted with water to 10-20 wave woods.
(4) it encapsulates, sterilizing.
2, second generation culture medium in the yeast liquid after first generation culture, will be added, additional amount is first generation culture 5-15 times of yeast liquid quality afterwards, closed culture 10-30 hours, cultivation temperature are 10-30 DEG C.
Preferably, the second generation culture medium the preparation method is as follows:
(1) peeled potatoes are taken, are cut into small pieces, the 2-8 times of water measured, 80 DEG C of immersion l-3h, filtering, 100 Pa sterilizing 20 is added min.
(2) glucose for being equivalent to 0.1 times of potato amount is added in above-mentioned potato leaching juice, heating is added after boiling and is equivalent to horse The agar of 0.1 times of bell potato amount continues to be heated to agar thawing
(3) 0.005-0.015 times of jamaicin for being equivalent to potato quality, stirring and dissolving are added in above-mentioned solution, encapsulation is gone out Bacterium.
(3) by above-mentioned kiwifruit peel filtering fermentation liquor, filtrate is boiled 5-10 minutes, is cooled to room temperature.
The preferred sterilizing can use high pressure steam sterilization, and sterilising conditions are 121 DEG C, 30min.
Present invention is characterized in that
1, the present invention tames saccharomycete using alkaloids jamaicin as domestication object, by two generation different culture mediums, Different barberry alkali concentrations tame saccharomycete, obtain that a kind of alkali resistance is strong, and the high optimization saccharomycete of activity under alkaline condition can It is effectively fermented to kiwifruit peel.
2, this law removes unfavorable hair by salt water washing by soaking by the specially treated for carrying out early period to kiwifruit peel Ferment object, while fermenting under alkaline condition, the effective component in kiwifruit peel can be preferably separated, nutritive value height is obtained Ferment.
