As preferably, the optimum combination of described antistaling agent is: epsilon-polylysine 0.01%+ chitosan 0.8%+ sodium diacetate 0.30%+EDTA0.01%.
This detailed description of the invention have employed five groups of meat samples to prove its effectiveness.With decompression method and antistaling agent compound use, Preservation Treatment process is the same, all uses the antistaling agent of optimum combination, is divided into five groups of meat samples so that different pressure process: first group-0.07~-0.09MPa;Second group-0.05~-0.07MPa;3rd group-0.03~-0.05MPa;4th group-0.01~-0.03MPa;5th group of 0~-0.01 Mpa.Evaluating with organoleptic indicator respectively, the mensuration of pH value, the mensuration of the mensuration of total plate count and total volatile basic nitrogen (TVB-N) proves the effectiveness of the inventive method.
Investigating each index (color and luster, organizational structure, meat flavour, meat soup) of subjective appreciation, according to organoleptic indicator's evaluation table such as table 1,10 specialty evaluation persons judge, final result is determined by " majority principle ".
Table 1 organoleptic indicator's evaluation table
Rating Score value Color and luster Organizational structure Meat flavour Meat soup
One-level fresh meat 4 Scarlet Flexible, tack-free Normally Limpid
Two grades of fresh meats 3 Fresh (brown red) Elastic not enough, infiltration Slightly abnormal flavour (alcohol smell) Slightly muddy
Slight rotten 2 Brown red Hands lax, viscous Abnormal flavour is dense More muddy
Rotten meat 1 Brown red turn white A large amount of infiltrations, viscous hands Strong stale flavor The most muddy
Each group meat sample organoleptic indicator's Comprehensive Assessment result such as table 2 during preservation and freshness, it can be seen that, the method of this detailed description of the invention has significantly control to the organoleptic indicator of Chilled Meats, still had before 13 days and well evaluate score value, minimum point is only 3.0, still falls within fresh meat scope, and in storage, the color and luster holding of meat is the most fine, illustrate that this compound storage practice has an obvious effect to the freshness date extending Chilled Meats, but each group to affect difference little.
The change of table 2 organoleptic indicator
The assay method of other indexs:
(1) pH values determination method
Adding 50ml distilled water after taking the chopping of meat sample, be placed on pH meter measurement, direct reading measures.Carrying out according to GB/9692.5 1998 " meat and meat products pH pH-value determination pH ", evaluation criterion is: one-level fresh meat 5.8-6.2, and two grades of fresh meats are 6.3-6.6, and rotten meat is more than 6.7.With reference to the variation diagram that Fig. 1, Fig. 1 are meat sample pH value
The result of Fig. 1 shows, in storage, the pH value of meat sample the most significantly changes, and when 17 days, in each group sample, maximum ph was only 6.5, and after 21 days, the pH value of meat sample the most slowly enters rotten meat scope.Visible, this complex method creates obvious effect to the pH value controlling Chilled Meats.The freshness date making Chilled Meats extends more than 7 days.
(2) mensuration of total plate count: carry out by GB/T4789.2-2003 " food hygiene microbiologic inhibition tests total plate count mensuration ".Evaluation criterion is: green meat is 104Individual/below g, secondary fresh meat 1~106Individual/g, rotten meat is 106Individual/more than g.
During preservation, the total plate count measurement result of each group sample is as shown in table 3.By table it can be seen that through the storage of 13 days, the total plate count of 5 groups of meat samples was up to 0.9 × 104Individual/g, still falls within one-level fresh meat scope.Until each group sample just reaches the index of rotten meat after 21 days.Visible, through the Chilled Meats that preservative processes, then through subatmospheric pressure storage, suppression microorganism growth is played obvious action.
The change (10 of beef cold fresh meat total plate count4Individual/g)
Table 3
(3) mensuration of total volatile basic nitrogen (TVB-N)
Take semimicro diffusion method, reference standard:
One-level freshness≤15mg/100g, two grades of freshness≤20mg/100g, rotten meat > 20mg/100g
During preservation, the TVB-N value of each group sample is with preserving the result of variations of natural law as shown in Figure 2.Fig. 2 is the variation diagram of the TVB-N value of meat sample.As seen from Figure 2, through the storage of 17 days, the maximum 15mg/100g of the TVB-N value of 5 groups of meat samples, still fall within one-level fresh meat scope.Until after 21 days, just reaching the scope of rotten meat, each group processes the decomposition for suppression Chilled Meats protein and has played obvious action.
By this detailed description of the invention it can be seen that the fresh meat after preservative processes places in decompression tank, freshness date has had obvious prolongation.Detection by each index: organoleptic indicator was when 13 days, and the score value of each group sample is still 3 points, belongs to fresh meat scope;Microbiological indicator was when 21 days, and maximum is 83.5 × 104Individual/g, minima is 40.0 × 104Individual/g, still falls within fresh meat scope;PH value was when 17 days, and maximum is 6.6, and minima is 6.3, still falls within fresh meat scope;TVB-N value was when 21 days, and only one group of sample is 20.5 mg/100g, has exceeded fresh meat scope, and other group samples all do not exceed standard.Be may certify that by these data, both approaches compound use can extend the freshness date of meat at about 7 days, also compensate for being used alone the more produced problems of decompression method simultaneously.
The fresh-keeping of meat should be a complicated system engineering.One-sided some factor of consideration is to extending fresh meat freshness date without positive effect.Factor and each factor importance in extending meat shelf period affecting meat shelf period should be considered.Shown by the research of above test, use decompression method to combine two kinds of methods of antistaling agent and Chilled Meats is carried out preservation and freshness, organoleptic indicator, physical and chemical index and the microbiological indicator of meat is all improved significantly.In storage, by the mensuration to above-mentioned each index, it can be seen that the Chilled Meats after processing with antistaling agent, then with decompression tank storage, make the freshness date of meat have significantly prolongation, at most extend about 10 days.In storage, the organoleptic indicator of meat does not changes significantly.The inventive method is thought, decompression method combines antistaling agent can make the freshness date of Chilled Meats have significantly prolongation.
