Destructive effects of citric acid, lactic acid and acetic acid on primary enamel microhardness
Objective: This study aimed to assess the destructive effects of citric acid, lactic acid and acetic acid produced from the fermentation of foods on primary teeth enamel. Methods: This in vitro, experimental study was conducted on 24 sound primary teeth. The teeth were polished with a fine abrasive paper under running water. Tooth pieces measuring 3 × 4 × 3mm were cut out of the teeth and s...
متن کاملInactivation of foot and mouth disease virus in skimmed milk with propionic acid, citric acid and hydrogen peroxide.
In order to protect farm animals from infections such as foot and mouth disease (FMD) and tuberculosis, the pasteurisation of milk and milk products designated for the feeding of animals is compulsory in Switzerland. Nowadays, milk products are often treated chemically with acids or with hydrogen peroxide in order to keep bacterial contamination low. The capacity of these chemical treatments to...
متن کاملMicrobial Propionic Acid Production
Propionic acid (propionate) is a commercially valuable carboxylic acid produced through microbial fermentation. Propionic acid is mainly used in the food industry but has recently found applications in the cosmetic, plastics and pharmaceutical industries. Propionate can be produced via various metabolic pathways, which can be classified into three major groups: fermentative pathways, biosynthet...
متن کاملEffect of citric acid concentration on the formation of diacetyl by certain lactic acid bactria.
Diacetyl has been associated with the "buttermilk off-flavor" sometimes found in orange juice and in frozen concentrated orange juice. Bacteria of the Lactobacillus and Leuconostoc genera have been identified as causative agents of this type of spoilage (Hays, 1951; Hays and Riester, 1952; Murdock et al., 1952, 1953; and Hill et al., 1954). Growth rates of these spoilage organisms have been inv...
متن کاملChemical Regeneration of Exhausted Granular Activated Carbon Used in Citric Acid Fermentation Solution Decoloration
An improved chemical regeneration of the granular activated carbon (GAC) exhausted by the color (pigments and pollutants) from citric acid fermentation solution (CAF) was investigated. In the experiments, improved means were adopted to advance the traditional chemical regenerating method and the adsorption capacity of the first time renewed GAC is 103% of original GAC. Using oxidan...
