Description

A kind of Fructus Rubi fermentation dry powder and preparation method thereof
Technical field
The present invention relates to a kind of food-processing method, be specially a kind of Fructus Rubi fermentation dry powder and preparation method thereof.
Background technology
Fructus Rubi fruit has the supporing yang improving eyesight of arresting seminal emission kidney tonifying, relieving alcoholic intoxication quenches the thirst, the effect of removing toxic substances of reducing phlegm, cure mainly suffer from a deficiency of the kidney, pass out semen, the disease such as drunk, erysipelas.The micro-hardship of leaf, the disease such as removing toxic substances, detumescence, sore etc., laryngopharynx swelling and pain, multiple abscess, mastitis.Except northeast, Gansu, Qinghai, Xinjiang, Tibet, all there is distribution in China all the other provinces, Korea, Japan, Burma, Vietnam.Fructus Rubi is shrub type fruit tree, and Eco-economic Type water and soil conservation shrub species is extensively cultivated already in Europe, the United States, and forms industrialized development, is also rapidly developed, is all extensively planted at a lot of provinces, municipalities and autonomous regions after introducing China.Because it has good nutritive value, medical value and edibility, so better economic benefit.
But existing Fructus Rubi powder, preparation method thereof, after main making beating, filtration, intensification spray drying.
Effectively health care and nutrition in Fructus Rubi is received relatively havoc and loses well by these methods, and color and luster is also difficult to keep original vivid color.
Summary of the invention
For above-mentioned technical problem, the present invention provides a kind of Fructus Rubi fermentation dry powder and preparation method thereof, is sufficiently reserved the health care in Fructus Rubi and nutrition is abundant, and can keep the bright of dry powder.
Concrete technical scheme is:
Fructus Rubi fermentation dry powder, is prepared gained by following methods:
(1), after the Fructus Rubi of select is removed foreign material, cleaning, add water and color fixative complexing agent, Fructus Rubi, water, color fixative complexing agent mass ratio be 1: 1: 0.004~0.006;
(2) said mixture is heated to 80 DEG C, is incubated 30min, obtains Fructus Rubi juice of precooking;
(3) by Fructus Rubi juice pulping, elimination core gained is Fructus Rubi serosity;
(4) Fructus Rubi serosity citric acid adjusts pH to 6.0-6.5;
(5) adding pectase in Fructus Rubi serosity and carry out enzymolysis, the addition of pectase is the 0.015~0.025% of Fructus Rubi slurry weight, hydrolysis temperature 38 DEG C, enzymolysis time 30min;
(6) the Fructus Rubi serosity after enzymolysis carries out vacuum concentration, and the temperature of vacuum concentration is 50~60 DEG C, is concentrated to the 20% of Fructus Rubi serosity;
(7) concentration Fructus Rubi is starched under 20-23 degree Celsius, add the ratio of 10-30 gram of active dry yeast (business is buied) according to the amount of 1000 milliliters of Fructus Rubi slurries, cultivate 10-20 hour;Obtain Fructus Rubi fermentation slurry;
(8) adding anticaking agents in the Fructus Rubi fermented slurry after fermenting and obtain mixing Fructus Rubi fermentation slurry, anticaking agents and the Fructus Rubi fermented slurry mass ratio after concentration are 0.1~0.2: 10;
(9) slurry that fermented by mixing Fructus Rubi carries out high pressure homogenize, and homogenizing temperature is 30 DEG C, and the pressure of first order homogenizing is 20MPa, and the pressure of second level homogenizing is 25MPa;
(10) slurry that fermented by the mixing Fructus Rubi after homogenizing carries out degassed, and degassed pressure is 0.9~0.92Mpa, and degassing time is 10~15min;
(11) the mixing Fructus Rubi fermentation slurry after degassed carries out vacuum lyophilization process;
(12) dry Fructus Rubi powder is carried out grinding, after 25 eye mesh screens, obtain Fructus Rubi fermentation dry powder.
Wherein, described color fixative complexing agent, with parts by weight, composed of the following components: sodium chloride: 1~4, potassium citrate: 0.5~0.8, sodium sulfate: 0.3~0.5, xanthan gum 4~8, gibberellins 0.2~0.5, hydroxypropyl methyl cellulose: 0.15~0.34.
