“…Mukherjee et al (1988) revealed that sorbic acid increased SCEs and frequency of MN at the highest dose (150 mg/kg body weight) in bone marrow cells of mice. Similar results about damaging effects of sorbic acid salts potassium sorbate were also obtained by Mpountoukas et al (2008) and by Mamur et al (2010) in human lymphocytes in vitro. Some authors compared the genotoxic effect of sorbic acid and its sodium and potassium salts.…”

“…Though food preservatives play an important role in the safety of food supply, many studies revealed the potential genotoxic and mutagenic effects of the additives (Hasegawa et al 1984;Schlatter et al 1992;Schiffmann and Schlatter 1992;Yılmaz et al 2008Yılmaz et al , 2009Mamur et al 2010;Zengin et al 2011). Hasegawa et al (1984) reported that SS showed genotoxic effects in Chinese Hamster V79 cells at 200-800 lg/ml concentrations in CAs, SCEs and gene mutation tests.…”

“…For these reasons, the aim of this study was to investigate the genotoxic and cytotoxic effects of SS by using CAs, SCEs, MN and comet assays in human lymphocytes in vitro. The analyses of CAs, SCEs and MN in human peripheral blood lymphocytes as well as comet assay are popular biomarkers for genotoxic, carcinogenic, and mutagenic effects (Garaj-Vrhovac and Zeljezic 2000; Yüzbaşıoglu et al 2006;Blaszczyk 2006;Yılmaz et al 2009;Mamur et al 2010;Zengin et al 2011).…”

“…Other studies have reported the lack of mutagenic andcarcinogenic potential in both in vitro and in vivo models (Ishidate et al, 1984;Münzner et al, 1990;Walker, 1990;Schiffmann and Schlatter, 1992;Mamur et al, 2010). However, prolonged storage of sodium sorbate has reportedly yielded an oxidative degradation product, 4, 5-oxohexanoate which is mutagenic in the Ames test (Jung et al, 1992;Schiffmann and Schlatter, 1992) and may be partly responsible for the weak genotoxic results reported in cultured Chinese hamster V79 cells and wing spot test of Drosophila (Hasegawa et al, 1984;Schlatter et al, 1992).…”

Majority of consumer goods are required to be presented with good aesthetics in order to improve acceptability in terms of colours and in some instances taste. When related to food, beverages and drug products, additives are usually added to mask un-inviting colours, obscure offensive odours and increase taste. Food additives therefore include colourants, sweeteners, preservatives and anti-caking agents. Admissible daily intake limits are often recommended for these additives. Being food products, the amount consumed over time may be subject to individual preferences and thus negating the desire to regulate and control the amount consumed cumulatively. There have been several concerns about the safety of food additives and several batteries of tests, and reports are available in literature. This review attempted to give an update on reports that have surfaced in literature over recent past on the use and safety of food colours and other additives. Some safety concerns have been related to three determinations; cytotoxicity, genotoxicity and induction or potential of inducing mutagenicity. In order to accomplish these targeted evaluations, several tests have been prescribed by International conference on harmonization (ICH), organization for economic co-operation and development (OECD) and European food safety authority (EFSA). It is observed that no single test can give a full proof of safety of these food colours and additives, hence minimal tests are recommended to be carried out in order to guarantee safety of these products. Survey of literature, revealed that once some approved additives or colours become a subject of safety concerns, comprehensive evaluations are carried out by researchers and these have often led to the de-classification of some hitherto reported agents as being non-genotoxic or non-carcinogenic. The declassifications of some food colors and additives as human carcinogens are regularly done following the comprehensive evaluation of results of mutagenicity and genotoxicity tests in vitro and some in vivo tests in mammalian tissues and whole animals. However, such declassifications are often done with caution and the implication is that regular and more comprehensive tests must be carried out. In addition, the requirements of testing for chronic exposures to this and other agents must be emphasized to prevent occurrence of subtle yet terrible side effects resulting from consuming sub-toxic doses of the additives over time.

“…It was reported that sorbic acid and its salts have a potential genotoxin hazard (Abe and Sasaki, 1977, Hasegawa et al, 1984, Ishidate and Odashima, 1977). Mamur's et al (2010) results also showed that potassium sorbate is genotoxic to the human peripheral blood lymphocytes in vitro.…”

Isolation of Antifungal Lactic Acid Bacteria from Food Sources and Their Use to Inhibit Mold Growth in Cheese

A large amount of cheese is lost every year due to mold contamination.Biopreservation, which is the use of biological entities (microbes) and their metabolites to suppress microbial spoilage instead of chemical preservatives has lately gained increasing interest. Lactic acid bacteria (LAB) have the potential for use in biopreservation, because they are safe to consume and naturally exist in many foods. In this study, fifteen strains of lactobacilli isolated from dairy products, vegetables, and fermented pickles were tested by agar overlay assay for their anti--mold activity. Six strains grown on MRS agar showed strong inhibitory activity against a target mold (Penicillium sp. at 10 5 spores/ml) isolated from the surface of Cheddar cheese. The isolates were identified by biochemical tests using API CHL50 strips. Five strains were identified as Lactobacillus plantarum, and one strain as Pediococcus pentasaceus. Well--diffusion method was used to demonstrate anti--mold activity in concentrated cell--free supernatants. Supernatants from all strains showed inhibition of the target mold (indicator). The anti--mold compound(s) produced by all the strains was heat--resistant (100 o C for 15 min). Supernatants from 5 strains retained the anti--mold activity when the pH was adjusted to 6.8 ± 0.2, while one v strain DC2 isolated from cheese lost its anti--mold activity at that pH. Temperature of incubation of cultures affected anti--mold activity. The optimum was 37 o C. Very little or no inhibition was noted when cultures were incubated at either 10 or 55 °C.A preliminary study of applying anti--mold lactobacilli in Cheddar cheese was completed. Anti--mold LAB was added to the cheese milk as an adjunct to give 10 5 cfu/ml. After 1--week and 1--month ripening, mold (10~20 spores) was added on to the surface, and the cheese was wrapped loosely. The appearance of the mold on cheese surface was monitored. Mold was not present on the 1--week old cheese "NB in milk" until the 6 th day after the control cheese (made without strain NB) showed signs of mold. The 1--month old cheese "NB in milk " extended the shelf life 17 days longer than the control cheese.
