Abstract

Lysozyme, a natural antibacterial, has potential use in several applications. Generally, it is obtained from chicken egg whites. However, the idea of using local duck eggs as a source of lysozyme is not wellknown. This study aimed to isolate and purify the egg white of Mojosari and Alabio ducks to characterize lysozyme. Additionally, the study analyzed the effect of temperature treatment on lysozyme enzymatic activity. Three different temperature treatments were used: Low Temperature Long Time (63 ℃, 30’), High Temperature Short Time (72 ℃, 15”), and sterilization (121 ℃, 15’). The Amberlite resin cation exchange chromatography method was successfully used to isolate and purify Mojosari and Alabio duck egg whites, achieving purity levels of 94.92-96.09%. The presence of lysozyme was confirmed by the existence of bands that were primarily composed of lysozyme. The results showed that each aspect of the characteristics of lysozyme and enzymatic activity were significantly affected (p<0.05) by the type of egg white. Enzymatic activity indicated that Alabio duck lysozyme was thermosensitive and could only survive at LTLT temperature, while Mojosari duck lysozyme could survive at LTLT and HTST pasteurization temperatures. However, both lysozymes did not survive the sterilization temperature.

Abstract

This aim of this study is to determine the effect of using propolis extract as edible coating for beefon chemical characteristics consisting of moisture content, malondialdehyde value and antioxidantactivity at room temperature storage. This research used randomized design with 4 treatments and 3replications. The treatment applied in this study was immersing the meat in propolis extract with differentconcentrations, that are 0.5%, 1.0%, and 1.5% propolis coating. Coating meat with the addition ofpropolis extract was able to have a significant effect at a concentration of 0.5% on water content and theantioxidant activity of coating meat (P <0.05). The addition of propolis extract at various concentrationscan maintain the quality of beef by reducing rancidity during storage. The increasing concentration ofpropolis extract caused the decreasing of MDA value.

Abstract

Broth is a product made from beef or poultry by cooking ingredients rich in protein and water, with or without the addition of spices, vegetable fat and sodium chloride. This study aims to determine the physicochemical properties including crude protein, ash, fat, carbohydrates, water activity, and pH as well as organoleptic tests of three types of broth from different chicken meat, namely broiler, free-range chicken, and IPB-D1 chicken. An organoleptic test was performed using quantitative descriptive analysis (QDA). The results showed that the different types of chicken strains did not significantly affect the value of water content, ash content, protein content, pH value and viscosity. The descriptive quantitative analysis (QDA) test followed by the ANOVA test showed that the difference in the types of chicken strains has no significant effect on the sensory attributes of chicken taste, salty taste, tastelessness, bitter aftertaste, and carnation aftertaste. Chicken broth made from native chicken gave the best characteristicresults for the analysis of physicochemical and organoleptic properties.

Abstract

Meltique beef was created by injecting vegetable oil emulsions into regular beef, but the high cost andoxidation susceptibility of canola oil limit its practicality. Palm oil, characterized by higher stabilityand local availability, was explored to improve physical properties and sensory qualities. The aim ofthis reserach was to analyze physical properties and sensory quality of roasted meltique beef injectedwith palm oil emulsion. Brahman cross sirloin cuts were injected with emulsions comprising oil, water,and soy protein isolate, prepared with different concentrations. The injected meats were grilled for 10minutes and assessed for pH, texture, cooking loss, and sensory attributes. Results showed that palm oilsignificantly enhanced texture and sensory properties, with palm oil at higher concentration being themost similar to Wagyu beef in marbling, tenderness, and flavor. The findings indicate that palm oil wasa cost-effective and stable alternative to canola oil for producing high-quality meltique beef, offering aviable solution for enhancing local beef products.
