Abstract
The invention discloses a kind of preservation method of strawberry, step one：Pluck：Plucked when the color of strawberry surface 4/5 reddens, selection head is big, strawberry without damaged, no disease and pests harm, hand wears gloves scissors and cuts off carpopodium, and sponge is put in the bottom of Picking basket, and the height of strawberry stacking is in 5 8cm；Step 2：Precooling：Strawberry after harvesting is sent into pre- cold-room at once, the temperature of pre- cold-room is located at 0 DEG C；Step 3：Immersion：Strawberry after precooling is immersed in 45 minutes in 4% calcium chloride solution, is pulled out and point disk dress, do not have disk to put 10 15 strawberries；Step 4：Pack：Strawberry in step 3 is put into silicon window bag together with plate, a piece of ethylene absorbent is put into silicon window bag, then sealed；Step 5：Refrigeration：The strawberry of pack is placed on temperature at 0 0.5 DEG C, in the freezer of relative humidity 85 95%, the present invention has the advantages that storage time is long, freshness is high.
Description
Technical field
The present invention relates to a kind of preservation method of strawberry, the technical field of preservation of fresh of strawberry is applied to.
Background technology
Strawberry nutrition value is abundant, is described as being " fruit queen ", contains abundant vitamin C, vitamin A, vitamin
E, nicotinic acid, vitamin B1, vitamin B2, carrotene, tannic acid, aspartic acid, copper, strawberry amine, pectin, cellulose, leaf
The nutriments such as acid, iron, calcium, ellagic acid and anthocyanidin.
Especially contained vitamin C, its content is all higher 7-10 times than apple, grape.And contained malic acid, lemon
Acid, vitamin B1, vitamin B2, and the content of carrotene, calcium, phosphorus, iron are also higher 3 to 4 times than apple, pears, grape.
Strawberry is of high nutritive value because of it, and sweet mouthfeel is deeply loved by the public, but the holding time of strawberry is very short
Temporarily, strawberry will rot for 2-3 days after plucking under field conditions (factors), if can not increase storage time strawberry does not transport mesh also
Ground may be rotten, bring huge economic loss to Planting household.
The content of the invention
For above-mentioned technical problem, the invention discloses a kind of preservation method of the strawberry that storage time is long, freshness is high.
A kind of preservation method of strawberry of the present invention, comprises the following steps that：
Step one：Pluck：Plucked when the color of strawberry surface 4/5 reddens, selection head is big, strawberry without damaged, no disease and pests harm,
Hand wears gloves scissors and cuts off carpopodium, and sponge is put in the bottom of Picking basket, and the height of strawberry stacking is in 5-8cm；
Step 2：Precooling：Strawberry after harvesting is sent into pre- cold-room at once, the temperature of pre- cold-room is located at 0 DEG C；
Step 3：Immersion：Strawberry after precooling is immersed in 4-5 minutes in 4% calcium chloride solution, is pulled out and point disk dress, do not have disk to put
10-15 strawberry；
Step 4：Pack：Strawberry in step 3 is put into silicon window bag together with plate, a piece of second is put into silicon window bag
Alkene absorbent, then seals；
Step 5：Refrigeration：The strawberry of pack is placed on temperature at 0-0.5 DEG C, in the freezer of relative humidity 85-95%.
Beneficial effects of the present invention：The present invention hardens strawberry surface by calcium chloride, prevents strawberry damaged, by adopting
Rapid cooling removal field heat after plucking, the respiration of strawberry, slows down the aging rate of strawberry always.
Specific embodiment
A kind of preservation method of strawberry of the present invention, comprises the following steps that：
Step one：Pluck：Plucked when the color of strawberry surface 4/5 reddens, selection head is big, strawberry without damaged, no disease and pests harm,
Hand wears gloves scissors and cuts off carpopodium, and sponge is put in the bottom of Picking basket, and the height of strawberry stacking is in 5-8cm；
Step 2：Precooling：Strawberry after harvesting is sent into pre- cold-room at once, the temperature of pre- cold-room is located at 0 DEG C；
Step 3：Immersion：Strawberry after precooling is immersed in 4-5 minutes in 4% calcium chloride solution, is pulled out and point disk dress, do not have disk to put
10-15 strawberry；
Step 4：Pack：Strawberry in step 3 is put into silicon window bag together with plate, a piece of second is put into silicon window bag
Alkene absorbent, then seals；
Step 5：Refrigeration：The strawberry of pack is placed on temperature at 0-0.5 DEG C, in the freezer of relative humidity 85-95%.
Example one：
Step one：Pluck：Plucked when the color of strawberry surface 4/5 reddens, selection head is big, strawberry without damaged, no disease and pests harm,
Hand wears gloves scissors and cuts off carpopodium, and sponge is put in the bottom of Picking basket, and the height of strawberry stacking is in 6cm；
Step 2：Precooling：Strawberry after harvesting is sent into pre- cold-room at once, the temperature of pre- cold-room is located at 0 DEG C；
Step 3：Immersion：Strawberry after precooling is immersed in 5 minutes in 4% calcium chloride solution, is pulled out and point disk dress, do not have disk to put 14
Strawberry；
Step 4：Pack：Strawberry in step 3 is put into silicon window bag together with plate, a piece of second is put into silicon window bag
Alkene absorbent, then seals；
Step 5：Refrigeration：The strawberry of pack is placed on temperature at 0 DEG C, in the freezer of relative humidity 85-95%.
General principle of the invention and principal character and advantages of the present invention has been shown and described above.The technology of the industry
It should be appreciated that the present invention is not limited to the above embodiments, described in above-described embodiment and specification is only the present invention to personnel
