The Effect Of Trehalose In The Preservation Of Chilled Meat

This paper mainly studied the effect of trehalose in the preservation of chilled meat for the sake of providing an method which is enable to realize preservation function independently, operate easily and effectively lower the cost for meat production enterprises. The method provides a kind of safe food additive. To solve the above problems, Trehalose was chosen as an ideal preservative from the numerous biological fresh-keeping agent. By adopting vacuum packaging and adding trehalose, the fresh-keeping effect of trehalose for the chilled meat was studied.To begin with, combined with vacuum packaging, different concentrations of trehalose preservation solution was used in chilled meat packaging. During storage, total bacterial counts, total volatile basic nitrogen value (TVB-N), pH, high ironmyoglobin, and sensory functions were tested as an indicator to study the changes in the quality of chilled meat after the treating with different concentration trehalose solution. Results showed that the preservation effect of different concentrations of trehalose preservation solution was different,4%>6%>8%>2%> blank group, and they have a shelf life of23,21.19,15,9days respectively. Optimal preservation effect of chilled meat was treated with4%trehalose preservation solution, it could extend the shelf life of chilled meat to23days. And the preservation effect was independent of trehalose concentration.Secondly,1%of acetic acid as solvent dissolved mixture different concentrations of trehalose compound preservation liquid, applied to preservation of chilled meat, and the change of the indicators are measured. Determination results showed that compound preservation liquid groups best6%s, more than25days, effect of keeping fresh is better than the blank control group.Above all, Trehalose has good preservation effect on chilled meat. Chilled meat treated with4%trehalose preservation solution has a shelf life of23days while treated with6%Compound preservation solution has a shelf life of25days. But due to acetate’s bad smell,4%trehalose preservation solution should be chosen for chilled meat preservation.
