Background technology
Large intestine body constantly produces active oxygen radical in metabolic process, is also constantly eliminated, make body maintain gain everything and lose nothing, low-level, stable equilibrium physiological free-radical contents.But large intestine is after being made into casing, because of the problem of holding time, can excessive free radicals be produced, cause body cell non-specific oxidation to damage, and it is rotten to cause casing.Because the position of endogenous antioxidant and radicals scavenging is sex-limited, antioxidation can only occur in around antioxidant Present site; And the fat-soluble free radical inspiring agent induction mostly acts on cell membrane, the effectiveness as water soluble antioxidant just receives a definite limitation, therefore, except non-added exogenous antioxidant, makes the free radical cancellation generated, to stop radical chain reaction.
Traditional casing store method is pickled method, and the method inhibits the growth of non-Halophiles preferably under high salt concentration situation, but there is the problem of following four aspects: (1) breakage rate is higher; (2) anti-oxidant solution is bad, easy variable color, rubescent; (3) need a large amount of clear water to clean before using, waste water and human resources; (4) the original elasticity of casing and toughness reduce greatly.Therefore invent a kind of brand-new store method, above technical problem can be solved most important comprehensively.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, now provide one can improve bactericidal and extend the pot-life and improve casing elasticity and toughness, and the preservation method of casing without the need to cleaning.
For achieving the above object, technical scheme of the present invention is: a kind of preservation method of casing, and its innovative point is: comprise cleaning, configuration fresh-keeping solution, soak, drain and seal step; Concrete steps are as follows:
(1) clean: be put in by casing in the clear water of flowing and repeatedly clean, described wash number is 3-5 time;
(2) prepare fresh-keeping solution: by the sodium pyrophosphate of 2-4%, the sodium dihydrogen phosphate of 11-14%, the alpha-tocopherol of 6-10%, the beta carotene of 6-10% and the nisin of 0.3-0.5 ‰ are evenly mixed in salt solution, stir, obtained fresh-keeping solution;
(3) soak: the casing of wash clean is put into the fresh-keeping solution prepared, sealing, soak 6-8 hour;
(4) drain: take out the casing soaked, drain under field conditions (factors);
(5) seal: the casing drained is packed, preserves under 1-10 DEG C of environment.
Further, the brine strength in described step (2) is 40-60%, and salt solution accounts for the 59-85% of total fresh-keeping solution volume.
Further, in described step (3), the immersion ratio of casing and fresh-keeping solution is 60-100 root/L.
Beneficial effect of the present invention is as follows:
(1) antistaling agent that the present invention selects is biological, effective sterilization and antibacterial while, also ensure that the security performance of food;
(2) antistaling agent that the present invention selects has the composition of water conservation, effectively can contain anti-oxidant, just ensure that the alcohol of color, and the elasticity of casing and toughness is obtained for raising, further ensure that the mouthfeel of the casing series after processing;
(3) change traditional pickled way, reduce breakage rate, and saved the expenditure with water and labour, reduce production cost.
Detailed description of the invention
By particular specific embodiment, embodiments of the present invention are described below, person skilled in the art scholar the content disclosed by this description can understand other advantages of the present invention and effect easily.
Embodiment 1
A preservation method for casing, comprises cleaning, configuration fresh-keeping solution, soaks, drains and seal step; Concrete steps are as follows:
(1) clean: be put in by casing in the clear water of flowing and repeatedly clean, wash number is 3 times;
(2) fresh-keeping solution is prepared: by the sodium pyrophosphate of 2%, the sodium dihydrogen phosphate of 11%, the alpha-tocopherol of 6%, the beta carotene of 6% and the nisin of 0.5 ‰ are evenly mixed in salt solution, stir, obtained fresh-keeping solution, brine strength is 40%, and salt solution accounts for 85% of total fresh-keeping solution volume;
(3) soak: the casing of wash clean is put into the fresh-keeping solution prepared, sealing, soak 6 hours, the immersion ratio of casing and fresh-keeping solution is 60/L;
(4) drain: take out the casing soaked, drain under field conditions (factors);
(5) seal: the casing drained is packed, preserves under 1 DEG C of environment.
Embodiment 2
A preservation method for casing, comprises cleaning, configuration fresh-keeping solution, soaks, drains and seal step; Concrete steps are as follows:
(1) clean: be put in by casing in the clear water of flowing and repeatedly clean, wash number is 5 times;
(2) fresh-keeping solution is prepared: by the sodium pyrophosphate of 4%, the sodium dihydrogen phosphate of 14%, the alpha-tocopherol of 10%, the beta carotene of 10% and the nisin of 0.3 ‰ are evenly mixed in salt solution, stir, obtained fresh-keeping solution, brine strength is 60%, and salt solution accounts for 59% of total fresh-keeping solution volume;
(3) soak: the casing of wash clean is put into the fresh-keeping solution prepared, sealing, soak 8 hours, the immersion ratio of casing and fresh-keeping solution is 100/L;
(4) drain: take out the casing soaked, drain under field conditions (factors);
(5) seal: the casing drained is packed, preserves under 10 DEG C of environment.
Embodiment 3
A preservation method for casing, comprises cleaning, configuration fresh-keeping solution, soaks, drains and seal step; Concrete steps are as follows:
(1) clean: be put in by casing in the clear water of flowing and repeatedly clean, wash number is 4 times;
(2) fresh-keeping solution is prepared: by the sodium pyrophosphate of 3%, the sodium dihydrogen phosphate of 13%, the alpha-tocopherol of 8%, the beta carotene of 8% and the nisin of 0.4 ‰ are evenly mixed in salt solution, stir, obtained fresh-keeping solution, brine strength is 5%, and salt solution accounts for 68% of total fresh-keeping solution volume;
