Casein/wax blend extrusion for production of edible films as carriers of potassium sorbate—A comparative study of waxes and potassium sorbate effect

Food Packaging and Shelf Life, 2018
Abstract Organic acids as potassium sorbate (KS) have a long history as being generally recognized as safe food preservatives. In this work, KS was incorporated in rennet casein sheets containing waxes (beeswax, candelilla and carnauba waxes) and its release and antimicrobial potential against Escherichia coli were analysed.

EFFECT OF POTASSIUM SORBATE ON THE GROWTH OF PSEUDOMONAS FLUORESCENS

Journal of Food Science, 1978
ABSTRACTTwo strains of Pseudomonas fluorescens were grown in trypticase soy broth (TSB; pH 5.5 and 6.0) at 24°C with and without potassium sorbate. Potassium sorbate was more effective in inhibiting the growth of both strains in the pH 5.5 TSB than in the pH 6.0 TSB.

Does potassium sorbate induce genotoxic or mutagenic effects in lymphocytes?

Toxicology in Vitro, 2010
The present study evaluates the genotoxic potential of potassium sorbate (PS) in cultured and isolated human lymphocytes. To assess the damage caused by PS in humans, we designed in vitro experiments by measuring chromosomal aberrations (CAs), sister-chromatid exchanges (SCEs), micronucleus (MN) and comet assays.

Influence of various parameters on the browning of potassium sorbate in the presence of amines

Food Additives and Contaminants, 2000
Potassium sorbate can undergo oxidation to form carbonyl moieties and cause browning. This investigation studied the fate of the compounds produced by auto-oxidation of potassium sorbate and measured the browning in the presence of amines. Experimental plans in which four factors were combined (temperature, oxygen, amine and light) led to the ...

Terahertz spectral detection of potassium sorbate in milk powder

SPIE Proceedings, 2017
The spectral characteristics of potassium sorbate in milk powder in the range of 0.2~2.0 THz have been measured with THz time-domain spectroscopy(THz-TDS). Its absorption and refraction spectra are obtained at room temperature in the nitrogen atmosphere. The results showed that potassium sorbate at 0.98 THz obvious characteristic absorption peak.

Potassium Sorbate Effect on Pigment Concentration of Refrigerated Beef

Journal of Food Science, 1988
ABSTRACTThe influence of potassium sorbate (SorK) on the relative concentrations of myo (Mb), oxi (MbO2,) and metamyoglobin (MetMb) of raw beef samples wrapped in plastic films of differcnt gaseous permeability was determined at 0°C and 4°C. Diffuse rcflectance spectrophotometry was applied to determine muscle pigmcnts concentrations.

Influence of potassium sorbate on the growth of yeasts and moulds in yogurt

International Journal of Dairy Technology, 2009
Yeasts and moulds are little affected by low pH and may cause spoilage of yogurt during storage. In the present study, potassium sorbate was added as a preservative in concentrations of 0.05%, 0.1% and 0.2%. The unpreserved yogurt showed unfavourable characteristics: yeast and mould counts and acidity increased.

EFFECT OF POTASSIUM SORBATE ON THE MICROBIOLOGY OF VACUUM‐PACKED POULTRY

Journal of Food Safety, 1984
Treatment of vacuum‐packed poultry pieces and muscle fillets with potassium sorbate decreased the rate of microbial development and increased shelf life when the substrates were stored at chill temperatures. Microbial growth on sorbate treated breast fillets was totally inhibited for up to 35 days at 2°C. The effect of sorbate was temperature dependent

Effects of Benzalkonium Chloride and Potassium Sorbate on Airway Ciliary Activity

ORL, 2012
<i>Objectives:</i> Preservatives are indispensable components of aqueous multidose topical formulations. The purpose of our study was to investigate the effects of two representative preservatives, benzalkonium chloride (BKC) and potassium sorbate (PS), on rabbit tracheal ciliary beat frequency (CBF).

Potassium Sorbate Inhibition of Mold in High Moisture Corn

Transactions of the ASAE, 1992
High moisture corn treated with potassium sorbate and potassium sorbate plus propylene glycol had a significantly longer safe storage period than untreated samples. Untreated corn showed a greater percentage of mold infected kernels, while a lesser percentage of infection was found in samples treated with the higher chemical levels.
