Quality of low-fat pork sausages with tomato powder as colour and functional additive during refrigerated storage

초록

Low fat pork sausages were formulated with tomato powder at 0% (C), 0.8% (T1), 1.2% (T2) and 1.5% (T3) levels in basic formula. With the increase in tomato powder concentration the lightness of the sausage decreased but the redness and yellowness increased significantly (p< 0.05). The pH values of T2 and T3 were significantly (p< 0.05) lower than the others, whereas, water holding capacity of T2 and T3 was significantly (p<0.05) higher. Thiobarbituric acid reactive substances, cohesiveness and springiness values of treated groups were significantly (p< 0.05) lower than those of control samples, however, hardness values of sausages with tomato powder were significantly (p<0.05) higher. The scores of overall acceptability in tested groups were significantly (p<0.05) higher than those of control samples after 30 days of storage. The low fat pork sausage with tomato powder up to 1.5% was found to be well acceptable up to 30 days at refrigerated storage. This new product will have special value due to the functional additive lycopene in tomato powder. ? 2010 Association of Food Scientists & Technologists (India).
