Abstract:The chemical characteristics and microbiological examination of vacuum packaged ground buffalo meat during cold storage for 24 days were determined in order to evaluate two different antimicrobial agents sodium lactate, sodium chloride and their mixture. The results indicated that the use of sodium lactate with or without sodium chloride delayed the proliferation of aerobic plate count, psychrotrophic count, and lactic acid bacterial count, and extended the shelf life up to more than 24 and 21 days respectively, compared to 8 days for the control samples. The TBA values for the samples treated by sodium chloride was not affected, while at the end of storage period the TBA values of samples treated by sodium lactate were significantly reduce the oxidation changes. Therefore, the use of sodium lactate with or without sodium chloride could be used to extend the shelf life of ground buffalo meat during refrigerated storage by reducing both chemical and microbiological changes.

Due to the greater thermal stability, chemical resistance, and dimensional stability of phenol formaldehyde (PF) resin, it has a very special position in the resin field. Nowadays, natural fiber reinforced PF composite materials are widely used. The objective of this study is to discuss the property improvements of natural fiber reinforced PF biocomposites. This review paper discusses thermal, electrical, diffusion, viscoelastic, tribological, morphological, and mechanical and biodegradability properties. Biocomposites will be a substitute for plastics which provides properties of both natural and synthetic part. The greaterthe pollution magnitude, the more devastating the impacts are on people’s health, the environment, and economic well-being. The main sources of pollution contributing to it are vehicle exhaust, open waste burning, lighting, heating and the combustion of various fuels for cooking. When compared with plastic materials, PF biocomposites are partially biodegradable, hence limiting the amount of pollution rate. And it has a wide range of applications, such as packaging, construction, automobiles, and household purposes. In short, this review aims to provide detailed information regarding PF biocomposites.
