摘要:

选用牛肉为原料,采用丙酸钙处理结合真空包装,在0℃、常温的条件下贮藏。通过测定贮藏期间挥发性盐基氮(TVB-N)、pH 值、菌落总数和感官评定,研究丙酸钙浓度对牛肉的保鲜效果的影响。实验结果表明:丙酸钙浓度3%,在0℃下,牛肉的贮藏期达到24d,常温下牛肉的贮藏期达到12d。经处理的牛肉,含钙量适度增加,提高了牛肉的营养价值。

Abstract:

The material of beef was treated by calcium propionate and vacuum-packaged, and then stored at 0 ℃ or room temperature. Through the measure of content of total volatile basic nitrogen (TVB-N), pH value, total bacterial count and sensory evaluation during storage, the fresh-keeping effects of different concentrations of calcium propionate on beef were investigated. The results showed that when the concentration of calcium propionate was 3%, the shelf lives of beef at 0 ℃ and room temperature reached 24 and 12 d, respectively. Furthermore, the calcium content and nutritional value in beef was promoted after the treatment of calcium propionate.

Key words: calcium propionate, beef, fresh-keeping
