| titleOfInvention | A kind of method for protecting swimming crab shell |
| abstract | The present invention relates to aquatic products refrigeration fresh-keeping technique field, more particularly to a kind of method for protecting swimming crab shell.This method comprises the following steps：（1）Cleaning；（2）Draining；（3）Precooling：Swimming crab after draining is placed in the range of 0 DEG C to 5 DEG C and carries out precooling 10 12 minutes, then the sprinkling of antifreezing agent is carried out to swimming crab surface, the consumption of antifreezing agent is 12% the 15% of swimming crab weight, antifreezing agent can use conventional commercial antifreezing agent, preferably, described antifreezing agent is mixed using glycerine, chitosan and acetic acid, and wherein the mass fraction of chitosan is 10 15%, acetic acid is 5 8%, and surplus is glycerine；（4）Gradient freezing：By step（3）Obtained swimming crab is placed in cryostat case, carries out gradient cooling in 10 DEG C, 20 DEG C, 30 DEG C, 45 DEG C of four temperature spots, each temperature spot is kept for 1~2 hour；（5）It is quick-frozen.This method is easy and effective, can make the cracking of the swimming crab shell after freezing ＜ 5%. |
