Abstract
The invention discloses a kind of coating liquids and its film air regulating fresh-keeping method of fresh evolution bamboo shoots, belong to food preservative technology field.The coating liquid of the fresh evolution bamboo shoots of the present invention：It is calculated in mass percent, is sterilizing drinkable water including chitosan 2 ~ 4%, nisin 0.2 ~ 0.6%, dehydroactic acid sodium 0.1 ~ 0.5%, sodium Diacetate 0.2 ~ 0.6%, potassium sorbate 0.2 ~ 0.6%, surplus.The processes such as the film air regulating fresh-keeping method of the present invention is peeled off including bamboo shoots, bamboo shoots water-removing, bamboo shoots cooling, bamboo shoots film, bamboo shoots drying, bamboo shoots controlled atmospheric packing, bamboo shoots dress cage, air-conditioned cold store fresh-retaining preserving.The number that the method for the present invention can reduce bamboo shoots breathing makes the mushroom corruptibility microbiological treatment dormant state that causes a disease in bamboo shoots body, and microorganism is made to stablize in bamboo shoots cell membrane, loses activity to form fresh-keeping effect；The addition of controlled atmosphere medium can enhance the integrality of bamboo shoots natural form, improve the stability of bamboo shoots endotrophic substance.
Description
Technical field
The present invention relates to a kind of coating liquids and its film air regulating fresh-keeping method of fresh evolution bamboo shoots, belong to food preservative technology
Field.
Background technology
Ming Dynasty's Li Shizhen (1518-1593 A.D.)《Compendium of Materia Medica》It records, " bamboo shoots Fang Erhou, property is hard, crisp, specially stores this bamboo shoot, often eats it, there is macrobiosis benefit
Longevity function ".In addition square bamboo shoots matter soft textive is thick, and color deliciousness is fresh, among coming from free of contamination mountain, can be rated as mountain delicacy delicacies, Gu Wei
Tribute, the present are cuisines, are spoken approvingly of in generation.Square bamboo is mainly grown in the plateau mountain area of 1400 meters to 2500 meters of height above sea level, and shape has in four directions
Rib has an angle, and bamboo shoot were not sent out in spring and cyclopentadienyl in the autumn, were to inhale the rare object that the anima growth of the Nature forms.It is only originated in the whole world
The national original ecological natural protection zone of Chongqing City Nanchuan District Jinfo Shan Mountain and the small fascine dam in Yunnan Yiliang County, Tongzi Guizhou Xian Qing dams
The ground such as mountain, Bai Zhishan.Fang Zhusun is pure natural health-care, is the king in bamboo shoot, and the world one is exhausted, and China is exclusive.Modern Green is eaten
Product scientific research department is detected, protein content 12% in square bamboo shoots, fat 0.4%, crude fibre 8%, also containing abundant amino acid, calcium,
The various trace elements such as iron, selenium, zinc and vitamin B1, B2, C etc..Then contributing to human body enterogastric peristalsis, promoting digestion for food, reaches
To weight-reducing, beauty and the special efficacy of prevention stomach and angiocardiopathy.It is micro- by iron, manganese, zinc, copper, the selenium in other side bamboo bamboo shoots etc.
The measure of the Major Element Contents such as secondary element and phosphorus, potassium, calcium, magnesium, sodium, finds its iron, manganese, zinc, copper and Determination of Potassium very
It enriches and apparently higher than most of Vegetables, the development and utilization for this precious autumn bamboo shoot resource provides mineral nutrition aspect
Scientific basis.With higher nutritive value, but since square bamboo shoots go out, bamboo shoot are fast, side's bamboo shoots season yield is big, excavation side bamboo shoots
