Abstract: A study was made on the products of degradation of Furylfuramide (FF) in food preservative and the following results were obtained. 1. Eight kinds of products were isolated by thin-layer chromatography (TLC) from FF which was dissolved in neutral or alkaline phosphate buffer and heated in water bath (90℃). 2. It was clarified by the TLC that FF added in food or phosphate buffer is degraded after becoming cis-FF during the process of heating (90℃). This cis-FF showed Rf 0.62 (WAKOGEL B-5, solvent: ethyl ether) and maximum absorption at 300mμ and 420mμ. Those products of degradation produced following the status of cis-FF which were constantly verified by the TLC were two yellow spots with Rf 0.16 and 0.18 both of which showed maximum absorption near 280mμ and 415mμ. 3. Most of the FF added to food remained as cis-FF. 4. Those degraded products of heated FF in phosphate buffer were two kinds of yellow materials in which nitro radical is believed to have been reduced to amino acid. Both of these materials showed maximum absorption at 345mμ and Rf 0.8 or more at the TLC. / 1. FFを中性,アルカリ性溶液中で加熱分解し,TLCで8種の分解生成物を確認した. 2. 食品中,水溶液中に添加されたFFは加熱分解時に異性化しシス型を経て分解することがTLCでわかった.この物質はRf 0.62,極大吸収300, 420mμを示す.シス型以後の分解物として常に現れるものはRf 0.16, 0.18で280, 415mμ付近に極大吸収を持つ2種の黄色物質確認された. 3. 食品中のFFの残存量として定量されているものは大部分がシス型である. 4. リン酸緩衡液(pH 7.0以上)中でのFFの加熱分解物中には,ニトロ基が還元されてアミノ基に変化したと思われる345mμに極大吸収を持つRf 0.8以上の2種の黄色物質が生成されることを確認した. 本報告は昭和42年7月29日,日本水産学会九州支部第三回例会で発表した.
