A kind of sprout brown rice rich in selenium asparagus fermented vinegar and preparation method thereof
Technical field
The invention belongs to health care edible vinegar manufacture field, be specifically related to a kind of sprout brown rice rich in selenium asparagus fermented vinegar and preparation method thereof.
Background technology
Vinegar can generate voluntarily in physical environment, and ancient times, the mankind just started edible vinegar from very early.In China, it has been generally acknowledged that vinegar starts when the Western Zhou Dynasty to be brewageed.The acetic acid of composition usually containing 3%-5% of vinegar, lactic acid, several mineral materials, what have also has a small amount of tartrate, citric acid etc.Vinegar has detumescence, detoxifies, helps digestion, effect of scattered silt, and drinking appropriate vinegar has larger help to healthy.
Asparagus formal name used at school reed bamboo shoot, its quality is fresh and tender, local flavor is delicious, tender good to eat, the trace element containing rich in protein, VITAMIN, mineral substance and needed by human body in asparagus stem, also the multiple steroid saponin material of distinctive asparagine is contained in addition in asparagus, all effective in cure to cardiovascular diseases, oedema, urocystitis, leukemia, also there is anticancer effect, the long-term edible useful taste of asparagus, have good result for the treatment of to human body numerous disease, thus asparagus is fabulous Dietotherapy health food.
Selenium, by the trace element as needed by human, has the good reputation of anticancer king.It has ten large effects: 1, improve body immunity; 2, anti-oxidant, delay senility; 3, Conservative restoration cell; 4, the treatment of diabetes is participated in; 5, cancer-resisting; 6, eyes are protected; 7, erythrocytic oxygen carrying capacity is improved; 8, cardiovascular and cerebrovascular diseases is prevented and treated; 9, removing toxic substances, gas defence, antipollution; 10, liver is protected.At present,
chinese Soclety of Nutritionadult's intake of recommending is 50-250 microgram every day, and China's 2/3 regional selenium intake is lower than minimum recommended value, and therefore, Chinese generally lack selenium.Given this, rich selenium in daily edible vinegar, effectively improves the intake of selenium.
Containing γ-aminobutyric acid (GABA) in sprout brown rice, it is a kind of naturally occurring nonprotein amino acid, is that inhibitory nerve important in mammalian central nervous system passes on material, has regulating effect to the several functions of body.When GABA in human body lacks, anxiety, uneasiness, the mood such as tired, worried can be produced, need to supplement to releive mood in time.It is approved as new resource food by health ministry, and have calm neural, anxiety, reduces blood pressure, and reduces blood ammonia, improves brain vigor, numerous effect such as to release the pressure.
Now, in order to increase the health-care effect of vinegar, existing correlative study person develops health vinegar, such as: the Chinese Patent Application No. CN201010187965.8 " producing and manufacturing technique of papaya ester
", Chinese Patent Application No. CN201210162462.4 " a kind of tea vinegar beverage and preparation method thereof
"etc..What study is all the health vinegar with traditional method preparation with effect in a certain respect, and composition is comparatively single, and mouthfeel is general, and the vinegar based article simultaneously with desirable mouth feel and nutritional health function is less.
Summary of the invention
The present invention is directed to the deficiency of above-mentioned existence, adopt sprout brown rice rich in selenium and asparagus mixed fermentation, during the fermentation, nutritive and health protection components in asparagus and sprout brown rice rich in selenium is incorporated in vinegar, both mouthfeel and the local flavor of vinegar had been improved, enhance again the health-care effect of sprout brown rice rich in selenium asparagus fermented vinegar, thus the health-care effect of vinegar and quality are significantly promoted.

comparative example 1:
The supplementary material kind that this embodiment uses with embodiment 1, quantity of adding, order of addition and the fermentation condition in each stage are all identical, only in comparative example, do not carry out selenium-rich germinated process to brown rice.
comparative example 2:
Do not use the enzymolysis solution of asparagus in this embodiment, namely lack the step (1) in example 2, all the other steps are all identical with example 2.
comparative example 3:
The difference of this embodiment and example 3 is steps (1) in comparative example 3, do not add zymin in (4), and other are all identical with example 3.
Asparagus vinegar prepared by embodiment 1-3 and comparative example 1-3, its attributional analysis is as following table:
Table 1 each embodiment attributional analysis table
From above data, use asparagus vinegar prepared by the present invention, VITAMIN, protein, amino acid and enzyme equal size are all higher than comparison example, especially selenium-rich germinated process is not carried out to brown rice in comparative example 1, r-Gamma-propalanine content is 0, selenium content is 0, does not use asparagus raw material in comparison example 2, and in the vinegar of preparation, vitamin contents is extremely low.Therefore, using the sprout brown rice rich in selenium asparagus fermented vinegar prepared of the present invention to make full use of, the glycolysis such as sprout brown rice rich in selenium and asparagus produces enriches enzyme system, VITAMIN and macroelement, trace element, obtained vinegar nutritive ingredient is many, local flavor sweet-smelling, mouthfeel is soft sweet refreshing, is the vinegar based article simultaneously possessing splendid mouthfeel and nutritional health function.
