Description
Technical field
The present invention relates to a kind of method of agricultural technology field, specifically, refers to a kind of method for storing juice of sugar grass stalks.
Technical background
Sugar grass is also sugared Chinese sorghum, sorgo, sweet stalk etc., is a mutation of common grain sorghum.Its similar sugarcane, is to produce the good raw material of alcohol fuel containing appreciable monose and abundant fiber using stalk as the organ of storage sugar.The strong adaptability of sugar grass, sucrose accumulation is fast, and growth period is shorter, only needs 3～6 months.The harvest time of sugar grass is about or so two weeks, and after sugar grass maturation, the carbohydrate (mainly sucrose) in stalk is easy to convert, therefore, it is necessary to harvest as early as possible and carry out storage work, otherwise, there is rotten, processing difficulties, the decline of juice yield in stalk.It is one of the study hotspot in current biomass energy field that juice of sugar grass stalks produces alcohol fuel, produce in Fuel Ethanol in juice of sugar grass stalks, the storage problem of juice of sugar grass stalks is not well solved, it has also become restrict the bottleneck of the technology development.To extend the production time that juice of sugar grass stalks produces alcohol fuel, utilization rate of equipment and installations is improved, make juice of sugar grass stalks ethanol production with more economy, sugar grass harvests the storing juice problem after processing of squeezing the juice just becomes a problem demanding prompt solution.
Literature searches of the Jing to prior art finds that adopting mostly will refrigerate at present after sweet sorghum stalk defoliation at -20 DEG C, but prolonged refrigeration consumes larger energy, and defrosting is also needed to when using, and crushing juice rate can be reduced.Also there is research covered rearing with plastic film and be filled with sulfur dioxide storage sweet sorghum stalk, Eiland have studied the impact of sulfur dioxide ground dosage and temperature to sugar grass kind ' beautiful Europe ' stalk segment storage performance in nineteen eighty-two.Test with the dosage (0.5% of 3 kinds of sulfur dioxide, 1.5%, 3.0%) with 5 kinds of reserve temperatures (2,12,16,22,32 DEG C), after each sample is preserved 3 months in insulating box, the sweet sorghum stalk of short section has been cut into the case where the sulfur dioxide controlled atmosphere of all 3 kinds of dosage is preserved, its total fermentable sugar does not significantly decline.It is expensive using sulfur dioxide controlled atmosphere storage facilities although this method effect is good, complex operation.In further retrieval, the document report related to " storage of juice of sugar grass stalks " is not yet found.
The content of the invention
The purpose of the present invention is for the deficiencies in the prior art, a kind of storage practice of juice of sugar grass stalks is provided so as to not only can energy saving, equipment that again need not be expensive, by once adding preservative, so that it may play various effects such as sterilization, anti-corrosion, fresh-keeping within the storage period of 1～2 month.
The present invention is achieved by the following technical solutions, comprises the following steps：
1. the harvesting of ripe sugar grass：From sugar grass must be new harvesting and without insect pest, rotten without going rotten, remove Sorghum vulgare Pers. leaf, the Chinese sorghum fringe on sugar grass.
2. prepare before squeezing the juice：First environment disinfected is carried out to squeezing job shop with the bleaching powder disinfectant of 5～10g/l to juice extractor and apparatus continuous sterilization 2～3 times with the bleaching powder disinfectant of 5～10g/l.With clean water sweet sorghum stalk surface, sweet sorghum stalk surface is cleaned with cotton, remove the silt of sweet sorghum stalk surface attachment.
3. the squeezing of juice of sugar grass stalks：Sweet sorghum stalk after process is moved into the squeezing job shop of sterilization, with squeezer juice of sugar grass stalks is squeezed, the juice of gained 16 layers of filtered through gauze of Jing again.Gauze for filtering will carry out ultraviolet sterilization process using before.
4. juice of sugar grass stalks tinning and storage：Before dress liquid, first cleaning fills the basin of liquid, and carries out sterilization treatment to basin.Juice of sugar grass stalks after process is fitted into basin, adds preservative, sealing to preserve at ambient temperature.Preservative used is at least containing benzoic acid or Sodium Benzoate, bleaching powder, sorbic acid or potassium sorbate, parabens one of which.
Described preservative, the usage amount of benzoic acid or Sodium Benzoate is the 0.01%～0.15% of juice of sugar grass stalks weight, bleaching powder usage amount is the 0.01%～0.2% of juice of sugar grass stalks weight, and sorbic acid or potassium sorbate, the usage amount of parabens are the 0.01%～0.1% of juice of sugar grass stalks weight.
The present invention is with juice of sugar grass stalks to preserve object, using preservative as the antistaling agent of juice of sugar grass stalks, mainly adopt the chemicals having no adverse effects to juice of sugar grass stalks to kill microorganism or suppress its activity to reach the purpose for extending juice of sugar grass stalks storage life.Wherein conventional preservative has benzoic acid or Sodium Benzoate, sorbic acid or potassium sorbate, bleaching powder, parabens etc..Benzoic acid or Sodium Benzoate, the antifungal mechanism of parabens are similar to, and mainly make the active suppressed of microbial cell respiratory system enzyme and electron transport system enzyme, and can destroy the structure of microbial cell film, so as to reach antisepsis.Both preservatives all have broad spectrum preservation ability and very strong suppression mould effect, especially cause the saccharomycete of food spoilage, mould effect most strong to Chang Yi；The antifungal mechanism of sorbic acid or potassium sorbate is to suppress microorganism especially dehydrogenase system activity in fungal cell, and combined with the sulfydryl in enzyme system, it is destroyed various enzyme systems, to reach antibacterial and corrosion-resistant purpose, its mould to contaminated food products, yeast and aerobic microorganism have obvious inhibiting effect；Bleaching powder belongs to oxidized form preservative, and its effective sterilization component is that the compounds such as calcium hypochlorite decompose the effective chlorine for producing, and it has strong killing action to bacterium, brood cell, yeast, mould and virus.
Juice of sugar grass stalks preserves 1-2 month under above-mentioned condition of the present invention, the brix of the juice of sugar grass stalks of addition preservative, the total reducing sugar that can ferment change are all little, juice of sugar grass stalks after storage is used for into alcoholic fermentation, alcoholic fermentation is normal, and the juice of sugar grass stalks after preserving need not carry out sterilization treatment before fermentation.Juice of sugar grass stalks typically needs heat sterilization before fermentation or reaches the purpose of sterilizing by adding preservative.But juice of sugar grass stalks is preserved using preservative, during the fermentation, the preservative being added in juice of sugar grass stalks in storage can very well suppress the pollution of other miscellaneous bacterias in juice, and do not affect the yield and quality of alcohol, so as to eliminate this link of sterilization treatment before fermentation, a part of energy has been saved.And the juice of sugar grass stalks of adding preservative agent does not occur as soon as within 1 week the phenomenons such as acidifying, mildew, and without fermentable sugars in its stalk juice, it is impossible to for alcoholic fermentation.
