Microbiology of Chili Bo, a Popular Malaysian Food Ingredient

Identification of lactic acid bacteria from chili bo, a Malaysian food ingredient.

Ninety-two strains of lactic acid bacteria (LAB) were isolated from a Malaysian food ingredient, chili bo, stored for up to 25 days at 28 degreesC with no benzoic acid (product A) or with 7,000 mg of benzoic acid kg-1 (product B). The strains were divided into eight groups by traditional phenotypic tests. A total of 43 strains were selected for comparison of their sodium dodecyl sulfate-polyacr...

Level of chemical and microbiological contaminations in chili bo (paste).

The objective of this study was to determine the level of preservatives and microbiological loads in various brands of commercially available chili bo (paste). Fifteen different brands of chili bo obtained from the local market and hypermarkets were analyzed for pH, moisture and benzoic acid content, microbiological loads (aerobic, anaerobic, aerobic spores, and fungi), and thermophilic microor...

Phytosterol: A Functional Ingredient in Food

165 Sterols are organic compounds, widely distributed in nature. Sterols are essential structural components of eukaryotic cell membranes, where they regulate membrane fluidity and permeability as well as membrane-associated metabolic processes. They occur naturally in animals, plants and fungi. Sterols of animals are called zoosterols. The most familiar type of animal sterol is cholesterol. Th...
