Shelf life, disinfectants

The recommended disinfectant solution must be able to establish a six-log reduction of each of the inoculated microorganisms within 5 minutes. For shelf-life determination, perform membrane hltration technique to conform to the manufacturer shelf life data. 

Thorough cleaning and disinfection of the equipment are essential parts of margarine operations to ensure optimal hygienic conditions. Combined with proper processing such as pasteurization, proper cleaning procedures help to ensure optimal product shelf life. 

Ascorbic acid is reasonably stable in a dry state with a shelf life of about 1-3 yr (23). However, it rapidly oxidizes in solution. A 1% solution may remain at approx 80% potency after 10 d. A 0.02% solution will degrade to 0% within 3 d. Ascorbic acid is also currently available in tablet form for dechlorination applications. Release of ascorbic acid-containing waters under some conditions may reduce the pH of the receiving streams. Use of vitamin C is reported to have other potential benefits as it is an essential vitamin for healthy fish (23). Also, it can easily strip manganese oxide stains from reservoir surfaces and thereby promote better disinfection (once the vitamin C is exhausted). Vitamin C (ascorbic acid) is NSF certified, allowing it to be used in drinking water treatment to remove or reduce chlorine levels. 

It is necessary to use organic acids to disinfect the carcasses in an environmentally friendly way and still produce the maximum shelf life for fresh meat. These methods must, therefore, be simple, long-lasting, and with a minimal effect on the sensory, chemical, and physical characteristics of the meat, and be inexpensive (Ogden et al., 1995).

If the product is not a disinfectant formula, it may be advisable to conduct adequacy of preservation tests. In these tests, the formula, as made for sale, is challenged with various microorganisms. This test sample is incubated for a time, and the amount of growth measured. Aging tests for the shelf life of the formula are also advisable, usually run for up to 12 to 18 weeks at both room temperature and elevated temperatures. 

Disinfectants and Cleaning Processes Disinfectants are an integral part of cleaning processes for aseptic manufacture. They are usually purchased as con> centrated stock solutions for use they should be diluted in water of Purified Water or Water for Injection quality. They should be filtered into white areas, usually, because of their viscosity, through 0.4S pm sterilizing filters. Each diluted batch should be allocated a shelf-life, and different disinfectants should be used in documented rotation. 

Pentachlorophenol. The evaluation of an immunoassay kit for the determination of pentachlorophenol (PCP) residues in water (IS) was carried out in conjunction with the current gas chromatography/electron capture detection procedure. The kit is based on a monoclonal antibody-based competitive inhibition Immunoassay and has a shelf-life of about one year. (CP is the second most heavily used pesticide in the USA. In Canada, it is registered as a wood preservative, insecticide and herbicide with the sodium salt of (CP often being used as a general disinfectant for trays in mushroom houses and wood preservative in crates. Since toxic pesticides of this type can pollute streams and ground water, it is necessary to monitor its presence.
