Fish is a food that in great demand by many people. are also easily damaged. Therefore, some fishermen use formalin as preservative for their caught fish. However, the of prohibited and considered dangerous because it can cause health problems. Hence, natural preservatives an alternative. The combination banana peel vinegar NaCl salt used inhibit growth microbes fish body. Furthermore, if combi...

Water hyacinth is a weed in Rawa Pening because of its rapid growth. A handling effort very crucial thing and must be done immediately. This study aims to characterize organic compounds liquid smoke from dried water hyacinth. ­­­­Characterization was carried out on which pyrolyzed at 200°C 600°C. Pyrolysis times were run 2 hours 6 hours. Liquid distilled before testing chemical composition usin...

ε-Poly-L-lysine (ε-PL) is a homopolymer linked by the peptide bond between the carboxylic and the epsilon amino group of adjacent lysine molecules. It is naturally occurring, water soluble, biodegradable, edible and nontoxic towards humans and environment. ε-PL shows a wide range of antimicrobial activity and is stable at high temperatures. This review focuses on various ε-PL producing strains,...

Cosmetics and topical products need not be sterile but may contain low levels of microbial load during use. This study was conducted to determine effectiveness of antimicrobial preservation during storage life of preparations and particularly the suitability of such preservative in terms of safety and broad spectrum activity. In this study, six formulations of both aqueous and oily cream were p...

Near infrared (NIR) spectroscopy is now a widely-used technique in the field of forest products, especially for physical and mechanical property determinations. This technique is also ideal for the chemical analysis of wood. There has been a growing need to find a rapid, inexpensive and reliable method to distinguish between preservative-treated and untreated waste wood. It has been demonstrate...

Several Canadian producers have implemented an inexpensive free-access feeding system modeled on Finnish guidelines,18 using formic acid as a milk preservative. The system mimics natural suckling and permits group social behavior. It allows for accelerated growth and changes labor requirements for calf rearing. Anecdotally, producers report less clinical cases of diarrhea and use of drugs for r...

The science and art of making beer, likely the oldest liquid fermented by humans, stretches over millennia. Production typically involves boiling beer wort together with hops, which acts as a natural preservative, but the generated iso-a-acids are known to be prone to decomposition, and consequently, more stable reduced hops extracts, such as the tetrahydro-iso-a-acids, have been developed. The...
