Water activity is an important property. It predicts stability with respect to microbial growth, rates of deteriorative reaction, and physical properties. Thus, worldwide food safety agency has incorporated water activity into safety regulations. These regulations detail specific requirements and practices to assure that products are produced under sanitary conditions and are pure, wholesome and […]
What’s a Ducted Fume Hood ? Many laboratories have ducted fume hoods installed. A chemical ducted fume hood is a significant safety device that is critical to maintaining acceptable laboratory air quality and preventing user exposure to potentially harmful chemicals. Yet, the fume hood is the most misunderstood and misused safety device in the laboratory. […]
WATER ACTIVITY (aw) is derived from fundamental principles of thermodynamics and physical chemistry. As a thermodynamic principle there are requirements in defining water activity that must be met. These requirements are: pure water (aw = 1.0) is the standard state, the system is in equilibrium, and the temperature is defined. In the equilibrium state μ = […]

A brief history of germicidal UV light : 2014 outbreak of the Ebola virus and the recent spread of the novel coronavirus disease 2020 (COVID-19) have generated renew interest in germicidal ultraviolet (UV) lamps for disinfection. UV radiant energy was first used for disinfecting surfaces in 1877, then in water since 1910 and in air […]
High-efficiency particulate air (HEPA) filter is widely use in medical and industrial clean rooms to filter air particulate and capture air-borne pathogens. In regarding to question, whether Air Purifier with HEPA filter is efficiently capture the virus that caused the COVID-19 virus, the answer is obviously – Yes. Evidences have showed that Covid 19 is […]
Technical write up on “Halal compliance for alcohol in beverages : a quantitative PT for low concentrations” In order to be Halal compliant and certified, foods must contain less than 1% ethanol than that been produced by natural (aerobic) fermentation. However, the level is lower for beverages, which must contain less than 0.1% ethanol in […]
