摘要

本研究的目的是定量测定猪胴体肉(RPCM)中生物胺的含量,并建立计算生物胺指数(BAI)的公式。对三种不同来源的RPCM样品进行了评价:1组实验生产的饲料;第2组:在专门处理猪在农场因非传染性原因死亡的工厂生产的饲料;第3组由商业加工厂生产。组1采用环境温度(ET = 25℃)和冷藏温度(RT = - 6℃)下的母猪胴体生产饲粮,并在0、24、48和72 h时分析其生物胺含量。采用高效液相色谱法测定各饲料中苯乙胺、腐胺、尸胺、组胺、酪胺、亚精胺和精胺的含量,并计算其BAIs。蒸放24 h后,组1饲料的苯乙胺、腐胺、尸胺和酪胺含量高于蒸放24 h后的组1饲料,而亚精胺和精胺含量则下降。

Quantification of biogenic amines and adaptation of an index as a quality indicator of rendered pig meals
The objective of this study was to quantify biogenic amines and to adapt equations for the calculation of the biogenic amine index (BAI) in rendered pig carcass meals (RPCM). Samples of RPCM from three different origins were evaluated: Group 1—experimentally produced meal; Group 2—meal produced in a plant dedicated to rendering pigs dead on the farm due to non-infectious causes; and Group 3—meal produced in commercial rendering plants. Group 1 meals were produced from sow carcasses that were stored either under environmental temperature (ET = 25 °C) or refrigeration temperature (RT = −6 °C), and their biogenic amine contents were analyzed at 0, 24, 48, and 72 h of storage. The levels of the biogenic amines phenylethylamine, putrescine, cadaverine, histamine, tyramine, spermidine, and spermine of all meals were determined by high-performance liquid chromatography, and their BAIs were calculated. Group 1 meals stored at ET presented higher phenylethylamine, putrescine, cadaverine, and tyramine contents compared with those stored at RT after 24 h storage, whereas spermidine and spermine contents decreased after 24 h of storage at ET. The adapted BAI can be used as a quality indicator of RPCM.

期刊介绍: Published since 1957, this quarterly journal contains new research on all aspects of animal agriculture and animal products, including breeding and genetics; cellular and molecular biology; growth and development; meat science; modelling animal systems; physiology and endocrinology; ruminant nutrition; non-ruminant nutrition; and welfare, behaviour, and management. It also publishes reviews, letters to the editor, abstracts of technical papers presented at the annual meeting of the Canadian Society of Animal Science, and occasionally conference proceedings.
