title: Effect of enrobing and antioxidants on quality characteristics of precooked pork patties under chilled and frozen storage conditions.
abstract: Enrobed or coated pork patties containing a (50:50) mixture of butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT) at a level of 100 ppm in the batter mix and meat emulsion were cooked and stored chilled (4±1 °C) and frozen (-18±1 °C) for evaluation of quality. Test samples were compared to control patties (neither enrobed nor antioxidant treated). After 35 days of refrigerated storage no significant difference (P>0.05) was found in pH, 2-thiobarbituric acid (TBA) and Warner-Bratzler shear force (WBSF) values between uncoated and treated samples. Similarly, enrobed patties showed no significant (P<0.05) decrease in TBA values compared to control patties, but had lower relative moisture loss at the 45th day of frozen storage. However, control patties had significantly (P<0.05) higher overall shear values than coated patties under the same storage conditions. Coated samples had higher microbial loads but below the acceptable limit. Total plate counts (TPC) in enrobed and control patties were around 3.48 and 3.05 log(10) cfu/g, respectively, whereas in frozen stored samples these numbers were 2.77 and 2.69 log(10) cfu/g at the end of storage. Sensory scores viz appearance and color, flavor, juiciness, texture, and overall acceptability were higher in treated samples than controls during the entire storage period.
