Abstract
Peeled sugar cane section is first soaked in the preservative liquid for 2-5 min, then drip-dried and finally packed into transparent composite plastic bag, which is afterwards vacuum pumped, soaked into hot water at 80-85 deg.c for 15-30 min to disinfect and cooled with cold water. The present invention can preserve peeled sugar cane without becoming yellow and changing in taste.
Description
The present invention relates to fresh-keeping liquid and the preservation method of a kind of edible fruits crop, be specially adapted to remove the peel the fresh-keeping of sugarcane.
Background technology of the present invention: existing sugarcane preservation method is the conventional storage fresh-keeping of belt leather.It is not enough point: the one, sugarcane cortex is hard, must peel with special planing tool before edible, topping, remove root, and its edible part is a juice, accounts for about 30～40% of its sugarcane total amount, and stays a large amount of residues, contaminated environment after eating; The 2nd, the sugarcane after the peeling, fresh keeping time is no more than 6 hours, otherwise, will turn to be yellow, go bad.
Purpose of design of the present invention: avoid the weak point in the background technology, design a kind of after the sugarcane peeling, can prolong composite fresh-keeping liquid and the preservation method of sugarcane shelf-life effectively, with guarantee that sugarcane after the peeling is non-yellowing before the deadline, never degenerate, mouthfeel is still good to eat.
Design of the present invention: the method that the present invention adopts physics and chemistry to combine prolongs the freshness date of sugarcane.The method of chemistry: adopt and contain fresh-keeping, the sterilization of composite fresh-keeping liquid immersion sugarcane that ascorbic acid, tartaric acid, potassium sorbate and sucrose constitute at least; The method of physics: adopt hot water sterilization, vacuum freshness retaining.Its design: 1. sugarcane contains ascorbic acid, tartaric acid, potassium sorbate, sucrose and aqueous solvent at least or contains ascorbic acid, sodium pyrosulfite, Acidum Citricum, Sodium Benzoate, sucrose and aqueous solvent at least with composite fresh-keeping liquid.Ascorbic acid is 0.05%～0.4%, tartaric acid is 0.2%～0.6%, potassium sorbate is 0.3%～0.7%, sucrose is 5%～15% or ascorbic acid is 0.05%～0.15%, sodium pyrosulfite is 0.05%～0.15%, Acidum Citricum is 0.1%～0.3%, Sodium Benzoate is 0.2%～0.8%, sucrose is 5%～15%, aqueous solvent is 80%～93%.2. sugarcane is used to remove the peel the preservation method of sugarcane with composite fresh-keeping liquid, earlier sugarcane is removed the peel, be cut into segment again, be 0.05%～0.4% at ascorbic acid then, tartaric acid is 0.2%～0.6%, potassium sorbate is 0.3%～0.7%, sucrose is 5%～15%, aqueous solvent be 80%～94% or ascorbic acid be 0.05%～0.15%, sodium pyrosulfite is 0.05%～0.15%, Acidum Citricum is 0.1%～0.3%, Sodium Benzoate is 0.2%～0.8%, sucrose is 5%～15%, aqueous solvent is to soak 2～5 minutes in 80%～93% composite fresh-keeping liquid of forming, treat that the sugarcane surface moisture drains, the ultraviolet ray irradiation is after 15～50 minutes, pack in the composite plastic film bag, automatic heat sealing when adopting vacuum packing machine to bleed, in the hot water with 80～85 ℃ of the dried sugarcane immersions after the vacuum packaging, sterilization 15～30 minutes is cooled off with cold water at last.3. technological process: sugarcane → cleaning → sterilization → peeling → segment → fresh-keeping liquid soaks → drains → ultraviolet sterilization → compound plastic bag vacuum packaging → pasteurization → cooling → finished product.Specify as follows: clean: selecting does not have the rotten dried sugarcane that goes rotten, and with the clear water flushing, cotton or hairbrush are cleaned the sugarcane surface simultaneously, thereby remove the silt of sugarcane surface attachment; Sterilization: sugarcane all should sterilization from removing the peel vacuum-packed job shop and apparatus.At first be job shop to be carried out ultraviolet sterilization handle.Every cubic metre space is shone with 2.3 watts ultraviolet lamp.Secondly going into operation with front irradiation about 4 hours every day, and, the workman will attach the names of pre-determined candidates before entering the workshop and change one's clothes, put on then in the bleaching powder disinfectant that footware immerses 100ppm to carry out disinfection, and the sterilization of in the hand pond, washing one's hands.After the workman sterilization, earlier with the bleaching powder disinfectant of 100ppm with equipment and apparatus continuous sterilization 2～3 times; Peeling: sugarcane moves into the job shop of sterilization after with the clear water wash clean, with the sugarcane planing tool epidermis of shooting off, and cuts away the tip of a branch and the base portion that can not eat; Segment: be cut into the uniform segment of length with the sugarcane that stainless steel knife will have been removed the peel, put into frame of plastic with holes; Composite fresh-keeping liquid soaks: according to ascorbic acid is 0.05%～0.4%, tartaric acid is 0.2%～0.6%, potassium sorbate is 0.3%～0.7%, sucrose be 5%～15% or ascorbic acid be 0.05%～0.15%, sodium pyrosulfite is 0.05%～0.15%, Acidum Citricum is 0.1%～0.3%, Sodium Benzoate is 0.2%～0.8%, sucrose is 5%～15%, aqueous solvent is 80%～93%, and (aqueous solvent is the clear water that boils the back cooling, but meeting sanitary standard for drinking water) ratio is mixed with composite fresh-keeping liquid, be stored in the clean container, fresh-keeping liquid wants the same day with joining the same day, the peeling sugarcane that to be cut into segment then connects frame of plastic and puts into composite fresh-keeping liquid together, soaks to pick up after 2～5 minutes; Ultraviolet sterilization: sugarcane picks up draining from composite fresh-keeping liquid when, shone about 15～30 minutes with ultraviolet lamp; Compound plastic bag vacuum packaging: dried sugarcane is quantitatively packed in the composite plastic film bag.The composite plastic film bag that method of the present invention is suitable for has 4 types of polypropylene/aluminium foil/polyethylene complex pocket, polypropylene, polyethylene complex pocket, nylon/polyethylene complex pocket, polyvinyl alcohol polyethylene complex pockets etc., can select wherein a kind of as required.After the sugarcane pack, heating is sealed when vacuumizing with vacuum packing machine immediately, and suction is 680～700 millimetress of mercury, about 200～240 ℃ of sealing temperature; Pasteurization: it is that sterilization is pulled out after 15～25 minutes immediately in 80～85 ℃ the hot water that the vacuum packaging bag of interior dress sugarcane is dropped into temperature; Cooling: the sugarcane after the sterilization is dropped in the cooling pond as early as possible and cools off, and reduces to about room temperature when temperature, pulls the pond out, dries the moisture content on packaging bag surface, can case warehouse-in or directly list marketing.
The present invention compares with background technology, has solved the difficult problem of peeling sugarcane fresh-keeping and storing, has alleviated environmental pollution, realized non-yellowing in the term of validity of sugarcane after peeling, never degenerate, mouthfeel remains unchanged good to eat purpose.
