Description
Technical field
The invention belongs to the food antiseptic field, relate to a kind of antiseptics for natural food.
Background technology
" bread is the staff of life, and food is with An Weixian ", food-safety problem has obtained the great attention of consumer and country.A large amount of both at home and abroad at present food preservatives that use are main with the chemical synthesis anticorrisive agent, and chemical preservative is low with its production cost, and advantages such as production technology maturation are in occupation of the leading position in anticorrisive agent market.But in recent years, the expert constantly queries to the security of chemical preservative both at home and abroad.Along with the raising of The development in society and economy and living standards of the people, people's concern food-safety problem is all the more constantly pursued more natural, safe, healthy food.Country is also in the supervision and management of strengthening year by year food security.A kind of nontoxic natural antiseptic agent of market in urgent need.
Summary of the invention
Goal of the invention: the purpose of this invention is to provide a kind of nontoxic antiseptics for natural food and preparation method thereof.
Technical scheme: antiseptics for natural food provided by the invention, process by the component of following parts by weight: lophatherum gracile 3-5 part, honeysuckle 1-3 part, purple perilla 1-3 part and cogongrass rhizome 1-3 part.
A kind of preferred as antiseptics for natural food of the present invention processed by the component of following parts by weight: 4 parts of lophatherum graciles, 2 parts of honeysuckles, 2 parts of purple perillas, 2 parts of cogongrass rhizomes.
The present invention also provides a kind of preparation method of above-mentioned antiseptics for natural food, may further comprise the steps:
(1) lophatherum gracile, honeysuckle, perilla leaf and cogongrass rhizome are mixed, boiling is filtered, and being concentrated into crude drug concentration is 1～1.3g/ml, gets decocting and concentrating liquid;
(2) in decocting and concentrating liquid, add ethanol, make concentration of alcohol reach 80-85%, leave standstill, filter, must filtrate;
(3) filtrating activated carbon decolorizing, ultrafiltration, drying promptly gets.
Wherein, in the step (1), each amount of water be each component gross mass 8-10 doubly, decocting time is 1-3h, the decoction number of times is 1-3 time; Through the control decocting condition, active ingredient that can the high efficiency extraction raw material makes preservative effectiveness better.
In the step (2), time of repose is 12-36h, through the control time of repose, can effectively separate impurity in the decocting and concentrating liquid.
In the step (3), the amount ratio of said active carbon and filtrating is (0.3-0.6) g:100mL; Bleaching temperature is 35-45 ℃, and bleaching time is 20-40min.
The present invention also provides the above-mentioned application of antiseptics for natural food in food antiseptic.This antiseptics for natural food all has significant inhibitory effect to strain growths such as staphylococcus aureus common in the food, Escherichia coli, bacillus subtilis and Candida albicans, can be effectively anticorrosion.
Beneficial effect: antiseptics for natural food provided by the invention is formed by the pure natural substance compatibility of integration of drinking and medicinal herbs such as lophatherum gracile, honeysuckle, has that antibiotic property is good, a characteristic such as safety non-toxic, sphere of action are wide.This natural antiseptic agent can be degraded to the utilizable composition of human body in human body alimentary canal, harm such as carcinogenic, the teratogenesis of greatly having avoided causing because of chemical preservative is residual in vivo, sudden change.
This antiseptics for natural food not only can effectively suppress microbial growth such as bacterium, mould in the food, prolongs effective period of food quality, plays the corrosion-resistant effect, also have simultaneously clearing heat-fire, promoting the circulation of qi wide in, the booster action curative effect of clearing damp and promoting diuresis.
