The specific embodiment
Below in conjunction with embodiment the present invention is made a detailed description.
A kind of composite preservative is prepared from by its weight ratio following raw material:
Nisin 5~20
Sodium dehydroacetate 10~60
Glucono-5~50
Different Vc sodium 5~40
Sodium chloride 5~50
Sodium phosphate trimer 1~50.
Among the present invention, nisin (Nisin), sodium dehydroacetate, glucono-, different Vc sodium act synergistically, and can effectively suppress the growth and breeding of bacterium, and fresh-keeping effect is obvious; And the fresh-keeping effect of different Vc sodium, sodium chloride (Nacl), sodium phosphate trimer (STPP) combination can enhancing antistaling agent, stablize meat and meat products the organoleptic indicator, the moisture holding capacity of enhancing meat and meat products, the yield rate of raising product.
Embodiment 1: the described composite preservative of present embodiment is prepared from by its weight ratio following raw material:
Nisin 5
Sodium dehydroacetate 25
Glucono-20
Different Vc sodium 10
Sodium chloride 30
Sodium phosphate trimer 10.
With preparation 100kg composite preservative is example; Its preparation method is following: nisin 5kg, sodium dehydroacetate 25kg, glucono-20 kg, different Vc sodium 10kg, sodium chloride 30kg and sodium phosphate trimer 10kg are joined in the mixer, obtain solid-state composite preservative after mixing.
In the present embodiment, use the method for composite preservative of the present invention following according to dissimilar raw meats:
(1) raw meat is cold fresh meat or cooling meat: use distilled water to be made into concentration composite preservative of the present invention and be 1% solution, both can adopt dipping method during use, also can adopt spray method.After dipping or the spraying, drain the moisture on cube meat surface a little, pack then.
(2) raw meat is the meat intestines based article that utilizes the preparation of beaters' skin or Collagent casing for sausages: in concentration is 1% composite fresh-keeping liquid, flood 2-5 second before can meat intestines based article pack or directly spray after boiling, dry then and pack.
(3) raw meat is a sauce halogen boiling meat products: can composite preservative pressed powder of the present invention directly be made an addition in the boiling meat products slaughterhouse; Addition is 0.5~1% of a raw meat weight; Under 90~100 ℃ of conditions, boiled 1~2 hour; Drain the moisture on meat products surface after taking the dish out of the pot, pack then.
The diffusing meat products that composite preservative of the present invention is mainly used in cold fresh meat (or cooling meat) and does not pack.Sodium phosphate trimer in the composite preservative and different Vc sodium not only improve the fresh-keeping effect of antistaling agent, and cold fresh meat (or cooling meat) is had certain water conservation and color-protecting function.
Discover nisin (Nisin) be used for cold fresh meat (or cooling meat) and not diffusing meat products fresh-keeping of packing truly have significant effect, can obviously slow down the increment of total number of bacteria.If Nisin is used with other components matching, can reduce its working concentration, thereby reduce cost, and obtain good effect.
Sodium dehydroacetate is the strongest to the restraint of mould, and mouldy to meat and meat products corruption in the valid density scope, generation green draws the inhibition effect of phenomenons such as haircuts obvious.
Different Vc sodium has been strengthened the antibacterial antiseptic effect of glucono-(GDL); Draw haircuts and reduction VBN that positive effect is arranged to suppressing meat and meat products; And cooperate sodium phosphate trimer and sodium chloride to use; Have effect preferably aspect meat and meat products organoleptic indicator stable keeping, the fresh meat color retention time is long, and reduces the juice seepage discharge.
Embodiment 1: the described composite preservative of present embodiment is prepared from by its weight ratio following raw material:
Nisin 5
Sodium dehydroacetate 25
Glucono-20
Different Vc sodium 10
Sodium chloride 30
Sodium phosphate trimer 10.
One, cooling meat is fresh-keeping
(1) processing of meat appearance: fresh cutting pig tenderloin is bought in the supermarket, cuts into the fritter about 200 gram/pieces at random, and the cube meat that will be used for experimental group takes out after second at composite preservative dipping 2-5, places the riddle draining 6-10min of alcohol disinfecting; Put into the plastic pallet of alcohol disinfecting then, cover with preservative film and pack; Replace composite preservative to prepare control group with distilled water simultaneously, and stick packet label.0-4 ℃ of refrigerator put in pallet packing preserved, whenever measure 1 time, carry out organoleptic examination, physical and chemical inspection and Micro biological Tests at a distance from sampling in 2 days.
(2) experimental result:
Group |
8 days |
20 days |
Control group |
Color changes and tangible foreign odor flavor occurs, loses edibility. |
|
Experimental group |
Keep the color of fresh meat, free from extraneous odour has the normal outward appearance viscosity of fresh meat. |
Keep the color of fresh meat, free from extraneous odour has outward appearance viscosity preferably, and microbial count propagation obtains obvious suppression. |
Two, utilize the fresh-keeping of sausage that beaters' skin makes
(1) laboratory is made fresh sheep casing by oneself and is recorded sausage; With composite preservative of the present invention the experimental group sausage is sprayed up to composite preservative and evenly to be attached to the sausage surface; Suspension draining 6-10min puts into the plastic pallet through sterilization then, covers with preservative film and packs; Prepare control group (without composite preservative spray sausage surface) simultaneously, stick packet label, 0-4 ℃ of refrigerator put in pallet packing preserved, whenever measure 1 time, supply to carry out organoleptic examination at a distance from sampling in 1 day.
(2) experimental result:
Group |
4 days |
10 days |
Control group |
The intestines surface begins to be clamminess, mouldy. |
|
Experimental group |
The intestines soma is refreshing, and freshness is high, free from extraneous odour. |
The intestines soma is refreshing, and freshness is high, free from extraneous odour. |
Experimental result explanation, different Vc sodium, STPP combination can stablizing meat and meat products the organoleptic indicator, raising meat and meat products be outlet capacity, and can strengthen the fresh-keeping effect of antistaling agent.And the synergy of Nisin, sodium dehydroacetate, glucono-, different Vc sodium plays an important role to suppressing the microbial growth breeding, and fresh-keeping effect is obvious.
