Abstract
The process of making freeze-dried aquatic products includes the steps of: washing, cooking, finishing, quick freezing, vacuum drying, waterproof packing, etc. The aquatic products thus produced have long preserving period, no damage of nutritive components, is convenient for carrying about and storing, and may be eaten directly.
Description
The invention belongs to field of processing of aquatic products, specifically is a kind of processing method of aquatic products of sloughing the shortening of moisture content through vacuum dehydration technology,
Aquatic products are loved by the people because of it is delicious, be that live in the house or going out to entertain all is that table is gone up delicacies, the fresh keeping time of aquatic products is all very short, be easy to spoiled rotten, prior art is freezing or drying with it, and prolonging fresh keeping time as far as possible, but the transportation of freezing aquatic products is deposited and all is subjected to condition restriction, and drying aquatic products have lost form and local flavor when fresh, and nutrition also is damaged.
The objective of the invention is to improve the deficiencies in the prior art and provide a kind of fresh keeping time long, be convenient to store and transport and be not subjected to condition restriction, can keep the processing method of the freeze-drying aquatic products of original nutrition, form and local flavor.The object of the invention realizes mainly being finished by following steps:
A, cleaning: aquatic products are rinsed well with clear water;
B, shortening: the pot that the aquatic products that clean up are put into water boil boils;
C, arrangement: will be the aquatic products of maturation are manual removes the part that shell etc. can not eat, only stay meat portion and cutting on request;
D, quick-frozen: the aquatic products of putting in order are contained put into the quick freezing repository that temperature is lower than-30 ℃ in the pallet and carry out quick-frozen, the central temperature of each entity is lower than-30 ℃;
E, vacuum drying: the aquatic products that quick-frozen is good are put into the vacuum storehouse that vacuum is lower than 100Pa and are dehydrated, and make the water content of each entity be lower than 3%;
F, damp-prrof packing: the aquatic products that drying is good require to pack into by weight and get final product in the damp-prrof packing.
Compared with the prior art the present invention has following distinguishing feature and good effect: the present invention adopts the quick-frozen final vacuum to dehydrate technology, well-done aquatic products are sloughed moisture content more than 97%, fresh keeping time is long, nutrition when fresh the same, can directly eat whenever and wherever possible, time saving and energy saving, easy to carry.
Embodiments of the invention are as follows:
Embodiment one: the freeze-drying peeled shrimp
With fresh shrimp clean up put into burn have boiling water the pot boil, claw peeled shrimp after pulling out with strainer, swing in regular turn and put into the quick freezing repository that temperature is lower than-30 ℃ in the pallet and carry out quick-frozen, take out after-30 ℃ when the central temperature of each peeled shrimp is lower than that to put into vacuum be that vacuum storehouse below the 100Pa dehydrates, when the water content of each peeled shrimp is lower than 3%, take out in addition damp-prrof packing finished product.
Embodiment two: freeze-drying scallop fourth
The scallop water is rinsed well, poured into to burn in the pot that boiling water is arranged and boil, claw scallop after pulling out, be cut into the fourth shape, following steps are with embodiment one.
Claims (2)
1, a kind of processing method of freeze-drying aquatic products is characterized in that this processing method mainly may further comprise the steps:
A, cleaning: aquatic products are rinsed well with clear water; Shortening: the pot that the aquatic products that clean up are put into water boil boils;
B, arrangement: will be the aquatic products of maturation are manual removes the part that shell etc. can not eat, only stay meat portion and cutting on request;
C, quick-frozen: the aquatic products of putting in order are contained put into the quick freezing repository that temperature is lower than-30 ℃ in the pallet and carry out quick-frozen, the central temperature of each entity is lower than-30 ℃;
D, vacuum drying: the aquatic products that quick-frozen is good are put into the vacuum storehouse that vacuum is lower than 100Pa and are dehydrated, and make the water content of each entity be lower than 3%;
E, damp-prrof packing: the aquatic products that drying is good require to pack into by weight and get final product in the damp-prrof packing.
2, aquatic products as claimed in claim 1 are meant the aquatic products that have shell.
