Rec-assay of food additives

Rec-assay of food additives. Kuroda, Koichi; Tanaka, Setsuko; Yu, Young Sik; Ishibashi, Takeji (Osaka Shiritsu Kankyo Kagaku Keukyusho, Japan). Nippon Koshu Eisei Zasshi, 31(6), 277-81 (Japanese) 1984. CODEN: NKEZA4. DOCUMENT TYPE: Journal CA Section: 17 (Food and Feed Chemistry) Food additives that inhibited growth in the spore-plate rec-assay method were g-undecalactone [104-67-6], cinnamaldehyde [104-55-2], and benzyl alc. [100-51-6]; oxalic acid [144-62-7] showed a weakly pos. reaction. Iso-amyl isovalerate [659-70-1], Et isovalerate [108-64-5], and Et acetoacetate [141-97-9] were neg. in spore-plate rec-assay, but showed weakly pos. reaction in test tube rec-assay. Citral [5392-40-5], decyl aldehyde [112-31-2], linalool [78-70-6], and perillaldehyde [2111-75-3] were neg. at a low concn. (<0.63 mL) and pos. at a high concn. (>1.25 mL) in spore-plate rec-assays.
