Effects of sorbic acid and its salts on chromosome aberrations, sister chromatid exchanges and gene mutations in cultured Chinese hamster cells

Effects of sorbic acid and its salts on chromosome aberrations, sister chromatid exchanges and gene mutations in cultured Chinese hamster cells. Hasegawa, M. M.; Nishi, Y.; Ohkawa, Y.; Inui, N. (Cent. Res. Inst., Japan Tob. and Salt Public Corp., Kanagawa 257, Japan). Food Chem. Toxicol., 22(7), 501-7 (English) 1984. CODEN: FCTOD7. ISSN: 0278-6915. DOCUMENT TYPE: Journal CA Section: 17 (Food and Feed Chemistry) Section cross-reference(s): 4, 6 The ability of sorbic acid [110-44-1] and its K [24634-61-5] and Na [7757-81-5] salts to induce chromosome aberrations, sister chromatid exchanges (SCE), and gene mutations in cultured Chinese hamster V79 cells was examd. Na sorbate caused significant induction of chromosome aberrations and SCE, and also induced 6-thioguanine-resistant mutations in a dose-dependent manner. The clastogenic potency of Na sorbate was <1/100 of that of the potent clastogen N-methyl-N'-nitro-N-nitrosoguanidine. The induction of SCE by Na sorbate was twice the control level, whereas that by Me methanesulfonate, a potent inducer of SCE, was 14 times the control level. The mutagenic potency of Na sorbate was <1/10 that of Et methanesulfonate, a potent inducer of mutation, when compared at an equitoxic level. Sorbic acid and its K salt induced chromosome aberrations, but only at the highest doses tested. These compds. also induced 1.2 times the control level of SCE, but neither compd. induced 6-thioguanaine-resistant mutations. The cytogenetic activity of Na sorbate was concluded not to be due to the effect of osmotic pressure or an impurity. Thus, Na sorbate is a genotoxic agent, although its potency seems to be weak, and sorbic acid and K sorbate are less genotoxic than the Na salt.

DOCUMENT TYPE: Patent CA Section: 17 (Food and Feed Chemistry) Meat products are dipped in or sprayed with a 5-18% soln. of Na [7757-81-5], K [24634-61-5], NH4 [62857-78-7], or Ca sorbate [90550-09-7] in water or in an aq. soln. of gelatin, starch [9005-25-8], or cellulose derivs. The treated products resist microbial contamination for 5 wk at 10° and relative humidity 90%. Thus, raw or cooked salami sausage products were dipped before drying into an aq. 18% soln. of K sorbate at 25° for 1 min and then transferred to a drying chamber (10° and 90% relative humidity). No microbial or fungal contamination on the surface of salami was obsd. after 5-wk ripening and drying. .
