Abstract
The invention discloses a process for preserving fresh water chestnut pulp by refrigeration, which comprises the steps as following: 1) the purchase and treatment of raw materials: the fresh water chestnut pulp is purchased from peasants or the market during the production season of the fresh water chestnut meat, the purchased fresh water chestnut meat is hulled and then cleaned by water and then filtered or dried with air; 2) the sodium chloride solution treatment: the fresh water chestnut pulp which is filtered for removing the water or dried with air is put in a container, and then the sodium chloride solution with a weight percentage concentration ranging from 5 percent to 6 percent is added in the container; the sodium chloride solution is added in the container until the fresh water chestnut pulp is completely immersed by the sodium chloride solution; 3) quick freezing: after being filled up with the sodium chloride solution, the container is immediately put in a household freezer for preserving by refrigeration; 4) thaw: the fresh water chestnut pulp after being rapidly frozen is thawed when being taken and used. The process of the invention can maintain the freshness of the fresh water chestnut pulp for a longer time.
Description
Technical field
The present invention relates to a kind of antistaling process of fresh vegetables, specifically a kind of fresh water caltrop pulp freezing preservation technique.
Background technology
After the fresh water caltrop pulp results,, can only carry out the sale of short-range transportation and short time if without Preservation Treatment, otherwise, just be easy to go bad.This characteristics that fresh water caltrop pulp is apt to deteriorate have determined to concentrate the season of gathering in the crops at fresh water caltrop pulp, go out the problem of cash sale difficulty easily; And, lack the problem of fresh water caltrop pulp supply again in other season.
Summary of the invention
The objective of the invention is to design a kind of fresh water caltrop pulp freezing preservation technique.
What the present invention will solve is that fresh water caltrop pulp goes out the cash sale difficulty in the fresh water caltrop pulp harvest season, and lacks the problem of fresh water caltrop pulp supply in other season.
To achieve these goals, the present invention has adopted following antistaling process:
1) raw material purchase and handling: produce at fresh water caltrop pulp and purchase fresh water caltrop pulp to peasant household or to the city season, after the next fresh water caltrop pulp of purchase is shelled, wash, again drainage or dry; 2) sodium chloride solution is handled: filtered water or the fresh water caltrop pulp that dries are put in the container, and then adding concentration expressed in percentage by weight in container is the sodium chloride solution of 5%-6%, till the amount that sodium chloride solution adds all is submerged with fresh water caltrop pulp; 3) quick-frozen: after filling it up with sodium chloride solution in the container, put the household freezer quick-freezing fresh-keeping at once into; 4) thaw: when taking, the fresh water caltrop pulp after quick-frozen is thawed.
The present invention can keep the freshness of fresh water caltrop pulp for a long time owing to adopted above technology, prolongs the selling time of fresh fresh water caltrop pulp effectively, thereby has both solved the supply problem of fresh water caltrop pulp, makes the grower of fresh water caltrop pulp obtain higher income again.
The specific embodiment
Below in conjunction with embodiment the present invention is further described.
Technology of the present invention comprises: 1) raw material purchase and handling: produce at fresh water caltrop pulp and purchase fresh water caltrop pulp to peasant household or to the city season, after the next fresh water caltrop pulp of purchase is shelled, wash, again drainage or dry; 2) sodium chloride solution is handled: filtered water or the fresh water caltrop pulp that dries are put in the container, and then adding concentration expressed in percentage by weight in container is the sodium chloride solution of 5%-6%, till the amount that sodium chloride solution adds all is submerged with fresh water caltrop pulp; Added sodium chloride solution is the solution that is cooled to natural temperature.3) quick-frozen: after filling it up with sodium chloride solution in the container, put the household freezer quick-freezing fresh-keeping at once into; The temperature of household freezer is controlled between subzero 16 ℃ to subzero 20 ℃.4) thaw: when taking, the fresh water caltrop pulp after quick-frozen is thawed.The container that needs when thawing to hold fresh water caltrop pulp is inverted, and with the timely flow container of solution that allows after thawing, prevents that fresh water caltrop pulp from by the sodium chloride solution submergence after thawing, influencing freshness.
Claims (4)
