Year: 2020
Type: article
Abstract: An experimental study was conducted from December 2018 to April 2019 to develop a method for improving tenderness and overall qualities of old aged beef carcass of local zebu cattle using plant proteolytic enzymes from papain (Carica papaya), bromelain (pineapple) and zingbain (Zingiber officinale) and their tenderizing efficacy were compared based on marinating time related with pH variation at different time interval (0hr, 4hrs, 8hrs, and 12hrs).Then, 3×3×3 cm chunks from Biceps femoris muscles of local zebu cattle (7 years age) were marinated with distilled water (control), powdered Carica papaya extract, Zingiber officinale extract and papain for 48 hours at 4 °C and subjected to various physicochemical, and sensory evaluations.Accordingly, the pH of the meat was significantly (p< 0.01) changed in all enzyme-treated samples compared to control.However, there was no significant (p> 0.05) change in the weight of the meat before and after marination in all enzyme-treated groups.The highest and least weight after cooking was recorded from papain (36.2±0.56gm) and zingbain (30.88±0.57gm),respectively.The weight of meat after cooking was significantly (p=0.0000)changed in all three enzyme treated groups.After cooking, significant pH variation on the meat was observed, with the highest (Zingbain, 0.7±0.012)and least was observed from papain (0.2±0.04) and bromelain (0.23±0.04).Improvement in flavor, juiciness, tenderness, and overall acceptability scores were observed in all enzyme-treated samples compared to controls.Thus, it is shown that papain treated meat samples received a higher (73.7%) level of customer satisfaction for appearance, flavor, tenderness, and overall acceptability and can be used as an effective alternative for meat tenderization.
