Abstract: We measured the POV and TBA values of ground ordinary muscles of horse mackerel and mackerel which had been stored at about 10℃ or 0℃ with or without mixing powdered antioxidant, i. e., BHA, Na-Erythorbate or mixture of BHA, BHT and Na-Erythorbate. The results as follows: With the samples stored at about 10℃, lipid Changes were rapid and variations of the TBA values were somewhat complicated. With the samples stored at about 0℃, lipid Changes were also rapid and the POV displayed rise and fall on the 7th day of storage but the TBA values hardly displayed any decrease throughout 10 days of storage. The antioxidants used in these experiments were all effective. It appeared that BHA was superior followed by the mixture and Na-Erythorbate, in that order. The addition of Na-Erythorbate both by itself and in mixture to the sample stored at about 0℃ accompanied decomposition of peroxides like in the case of non-addition of antioxidants. However, the addition of BHA by itself appeared not to accompany decomposition of peroxides. / マアジおよびマサバの普通肉を擂潰したもの,およびこれらに,BHA, Na-Erythorbateまたは混合抗酸化剤(BHA, BHTおよびNa-Erythorbate)をそれぞれ粉末のまま混和したものを,0℃または10℃付近に貯蔵して,その間におけるPOVおよびTBA値を測定した.その結果: 10℃付近で貯蔵した場合の脂質の変化は急速で,TBA値の変化は複雑であった. 0℃付近で貯蔵した場合の脂質の変化もかなり急速であるが,約10日間の貯蔵においては,POVは貯蔵後7日目を境として増減を示し,その間において,TBA値の変化には途中で減少することがほぼ見られなかった.使用した抗酸化剤はいずれも効果を示したが,これら実験の範囲ではBHAが最も効果的で,混合抗酸化剤がこれにつぎ,Na-Erythorbateは劣っている.0℃付近の貯蔵においてはNa-Erythorbateを単独あるいは混合抗酸化剤として使用したいずれの場合もperoxideの分解を伴なう.これらの点は抗酸化剤を使用しない場合と同様であった.しかしBHAを単独に使用した場合には,peroxideの分解は,ほぼ見られなかった.
