RESUMO
Cooked buffalo tripe rolls prepared from a combination of buffalo tripe and buffalo meat by using mincing and blade tenderization process were stored at 4 ± 1 °C in polyethylene teraphthalate laminated with polythene (PET/PE) pouches under vacuum packaging condition. The samples were evaluated for physico-chemical parameters, microbial quality and sensory attributes at regular intervals of 0, 7, 14, 21 and 28 days of storage. Significant changes were seen in physico-chemical, microbial and sensory characteristics of BTRs during storage at refrigeration temperature (4 ± 1 °C) under vacuum packaging condition. All microbial counts were well within the acceptable limits and the products did not show any signs of spoilage. Thus, BTRs prepared by mincing or BT can be best stored up to 28 days at 4 ± 1 °C under vacuum packaging.
RESUMO
Smoked buffalo rumen meat products were prepared from 3 times blade tenderized buffalo tripe with 5.0% ginger extract and were subjected to various physico-chemical parameters, microbial profile and sensory quality at 25 ± 1 °C under aerobic packaging. All physico-chemical parameters, microbial counts and sensory evaluation score of ginger extract treated buffalo rumen meat product were higher compared to control. pH, moisture content, thiobarbituric acid, tyrosine values, total plate, yeast and mould and staphylococcal counts were increased and extract release volume were decreased significantly with increasing storage period. Throughout the storage period, all microbial counts and sensory evaluation score were within the acceptable limits up to storage period of 15 days at 25 ± 1 °C in LDPE pouches under aerobic packaging.
RESUMO
Cooked buffalo tripe rolls (BTRs) were prepared from a combination of buffalo tripe (75%) and buffalo meat (25%) by using mincing (M-BTR) and blade tenderization (BT-BTR). They were stored at 4±1°C and studied for various physico-chemical, sensory and microbial qualities. Significantly (P<0.01) higher pH, shear force value, diameter shrinkage and fat percentage were observed in M-BTR and BT-BTR than control product (100% minced buffalo meat). The product yield and drip loss percentage were significantly (P<0.01) lower in BT-BTR, whereas drip loss percentage was significantly higher in M-BTR compared to controls and BT-BTR. No significant change was noticed in protein and moisture content between the different products. All physico-chemical parameters and sensory evaluation scores of M-BTR were comparable with control. Significant (P<0.01) increases were noticed in pH, moisture content, thiobarbituric acid and tyrosine values with increasing storage period, whereas the extract release volume decreased significantly. All microbial counts and sensory evaluation scores were within the acceptable limits until 15 days of storage at 4±1°C in low-density polyethylene pouches stored aerobically.
