3.1 Chemical composition
Chemical compositions of Nham, before and after fermentation, are shown in Table 1. Except for fat content, no marked differences in the composition of Nham were observed at the end of fermentation (P > 0.05). As a major constituent, water accounted for approximately 71%, followed by protein (20%) and trace amounts of ash and lipid. Nham proteins mainly originated from minced pork and cooked pork rind, two major ingredients in Nham raw mix, whereas ash content mainly came from salt and others additives. Lipid of Nham was in the range 2–3%. Compared to those reported by Lodge, Sarkar, and Kramer (1978), the values obtained were in agreement with those found in pork meat (2.9–3.2%). Nevertheless, they were obviously lower than those of other fermented sausages, which were generally up to 50% (dry basis). Since lean meat and cooked pork rind, used in Nham, contained no visible fat, lipids were probably derived from intramuscular lipids from minced pork and cooked pork rind.
