소금과 아질산염 처리수준에 따른 건염햄의 이화학적 특성

The aim of this work was to analyze the effects of salt and NaNO2 on weight loss, proximate compositions, chemical parameters and texture characteristics of dry-cured ham processed using Korean methods. Four different treatments were considered: The HS group of 3 hams (11.30 kg) was salted with 9.2 g/kg salt (w/w) (high salt batch), the HS+NaNO2 group of 3 hams (10.65 kg) was salted same as HS group and added 100 ppm NaNO2. The LS group of 3 hams (11.42 kg) was salted with 6.2 g/kg salt (w/w) (Low salt batch), the LS+NaNO2 group of 3 hams (10.62 kg) was salted same as LS group and added 100 ppm NaNO2. The highest weight losses took place at the drying stage (27.46, 28.25, 26.99, and 28.42%). However, there were no significant differences in the weight losses between treatments (p>0.05). The moisture content was significantly affected with addition of NaNO2 (p0.05). The processing conditions did not significantly affect the lightness (L), redness (a), and h° of biceps femoris muscles (p>0.05). The yellowness (b) and chroma in biceps femoris muscle from HS+NaNO2 hams were significantly higher than in the muscles from HS and LS hams.
