Description
Technical field
The invention belongs to bamboo shoot process fields, and in particular to a kind of phyllostachys pracecox shoots preservation method.
Background technology
Bamboo shoots are one of traditional Forest Vegetables, it is more rich in sugar, protein, cellulose, mineral element and vitamin etc.
Kind nutritional ingredient, delicious flavour is full of nutrition, is always liked by people.Containing 18 kinds of amino acid in bamboo shoots, and rich in people
Body essential amino acid contains total amino acid content about 29% in fresh bamboo shoot.Bamboo shoots are also containing various trace elements needed by human, such as Se
With Ge etc..It studies and shows that bamboo shoots are full of nutrition, high protein, low fat, delicious flavour is a kind of with health-caring function
Forest Vegetables have the plurality of health care functions such as weight-reducing, anti-intestinal cancer, reducing blood lipid, anti-aging.
But the problem of utilizations of bamboo shoots and processing are faced with preservation, picking time concentrates, and freshness date is shorter, adopt rear bamboo shoots by
Wound and nutrient stress cause breathing, electrical conductivity and content of lignin rise, and soluble protein and other nutrients decompose, and make its content
Decline, aging aggravation.In recent years, the use on bamboo shoots with canning, is pickled and the forms such as drying in the market, throughout the year for consumption
Person uses, but converted products loses the original flavor of fresh bamboo shoot and texture.
Bamboo shoots remove the bamboo sheaths of bamboo shoots of outer quilt（Bamboo shoot shell and aging base portion）, edible rate reach 50-70%.Therefore, process is micro-machined
Bamboo shoots, it is not only convenient, but also processing loss is reduced, flavor preserves more complete.Currently, fresh-cut bamboo shoots（Remove outer quilt
Bamboo sheaths of bamboo shoots）It is sold in the form of clean vegetables in many big supermarkets, but lignifying and brown stain easily occurs.Therefore, research and development can be effective
Delay fresh-cut lignification of bamboo shoot and the preservation method of brown stain generation that there is very important application value.
The content of the invention
A kind of phyllostachys pracecox shoots preservation method it is an object of the invention to provide soft taste, with toughness.
To reach above-mentioned requirements, the present invention adopts the technical scheme that：A kind of phyllostachys pracecox shoots preservation method is provided, including following
Step：
In 30 minutes, phyllostachys pracecox shoots are immersed in the mixture of ice and water of 7-9 times of volume after phyllostachys pracecox shoots harvesting, stir 5 minutes, make
It obtains phyllostachys pracecox shoots bamboo shoot temperature and 3 DEG C is cooled within half an hour；
The root of bamboo shoots is immersed in fresh-keeping solution 5-10 minutes, gently gets rid of raffinate, cold wind dries；The fresh-keeping solution is
The mixed solution of carbendazim and sodium propionate, the mass percent concentration of carbendazim is 0.45%-0.65% in the fresh-keeping solution, third
The mass percent concentration of sour sodium is 0.1%-0.2%；
10-45g chitosan sugar is dissolved in 1 liter 2% of citric acid solution, plastics is made, the phyllostachys pracecox shoots in above-mentioned steps are soaked
10-25 seconds not in plastics, raffinate is gently got rid of, standing dries film forming；
By oxygen：Carbon dioxide is 1.5:8.5-2.0:3.0 volume ratio prepares oxygen, carbon dioxide gas mixture, then adulterates
The nitrogen of 5-30% volumes prepares the mixed gas of oxygen, carbon dioxide and nitrogen for the air conditioned storage of phyllostachys pracecox shoots；It is placed on oxygen
Phyllostachys pracecox shoots food-grade packaging of aluminium foil bag in the mixed gas of gas, carbon dioxide and nitrogen.
Compared with prior art, the present invention has the following advantages：A kind of broad-spectrum germicide of carbendazim, to various crop by
Fungi（Such as Fungi Imperfecti, more sac fungus）Caused disease has control effect；Sodium propionate is a plant growth regulators, can be adjusted
The effects that saving Morphological Differentiation, increasing resistance, the two, which compound, to adjust to use can significantly extend the guarantor for adopting rear new fresh bamboo shoots
Hide the time limit.
Specific embodiment
To make the purpose, technical scheme and advantage of the application clearer, specific examples below is made the application into one
Step ground is described in detail.For the sake of simplicity, some technical features known to those skilled in the art are omitted in being described below.
The present embodiment provides a kind of phyllostachys pracecox shoots preservation methods, comprise the following steps：
In 30 minutes, phyllostachys pracecox shoots are immersed in the mixture of ice and water of 7-9 times of volume after phyllostachys pracecox shoots harvesting, stir 5 minutes, make
It obtains phyllostachys pracecox shoots bamboo shoot temperature and 3 DEG C is cooled within half an hour；
The root of bamboo shoots is immersed in fresh-keeping solution 5-10 minutes, gently gets rid of raffinate, cold wind dries；The fresh-keeping solution is
The mixed solution of carbendazim and sodium propionate, the mass percent concentration of carbendazim is 0.45%-0.65% in the fresh-keeping solution, third
The mass percent concentration of sour sodium is 0.1%-0.2%；
10-45g chitosan sugar is dissolved in 1 liter 2% of citric acid solution, plastics is made, the phyllostachys pracecox shoots in above-mentioned steps are soaked
10-25 seconds not in plastics, raffinate is gently got rid of, standing dries film forming；
By oxygen：Carbon dioxide is 1.5:8.5-2.0:3.0 volume ratio prepares oxygen, carbon dioxide gas mixture, then adulterates
The nitrogen of 5-30% volumes prepares the mixed gas of oxygen, carbon dioxide and nitrogen for the air conditioned storage of phyllostachys pracecox shoots；It is placed on oxygen
