摘　　要：旨在为不同传统米面食品煎炸加工提供参考,以大豆油为煎炸油,糯米糍粑、小麦油糕和黄米年糕为煎炸食材,探究煎炸过程中大豆油酸值、过氧化值、p-茴香胺值、全氧化值、极性化合物含量和脂肪酸组成的变化情况。结果表明:由于不同煎炸食材的水分、脂肪及抗氧化物质等的含量和组成存在差异,煎炸糯米糍粑的大豆油酸值显著低于煎炸其他两种食材大豆油的(p<0.05);在煎炸过程中,各体系过氧化值呈上下波动趋势;在煎炸2~24 h时,煎炸3种食材大豆油的p-茴香胺值大小顺序为煎炸糯米糍粑大豆油>煎炸小麦油糕大豆油>煎炸黄米年糕大豆油;全氧化值的变化趋势与p-茴香胺值基本一致;煎炸糯米糍粑、小麦油糕和黄米年糕大豆油的极性化合物含量分别在煎炸20、18、18 h时已超过国标限量(≤27%),其中煎炸黄米年糕大豆油极性化合物含量增加幅度最大;在煎炸24 h时,煎炸3种食材大豆油的反式脂肪酸含量大小顺序为煎炸黄米年糕大豆油>煎炸小麦油糕大豆油>煎炸糯米糍粑大豆油,且存在显著差异(p<0.05)。综上,由糯米、小麦和黄米制作的传统米面食品会对煎炸油的品质产生不同影响,在煎炸期间应以食材对煎炸油品质的具体影响为依据做出生产调整。Aiming to provide a reference for the frying processing of different traditional rice and flour foods, soybean oil was used as the frying oil, and glutinous rice cake, wheat oil cake and yellow rice cake as the frying ingredients to investigate the changes in the acid value, peroxide value, p-anisidine value, total oxidation value, polar compounds content and fatty acid composition of the soybean oil during frying. The results showed that due to the differences in the contents and compositions of moisture, fat and antioxidants of different fried ingredients, the acid value of soybean oil frying glutinous rice cake was significantly lower than that of soybean oils frying the other two ingredients (p<0.05). During the frying process, the peroxide value of each system showed an up-and-down trend;in the 2-24 h of frying, the p-anisidine value of soybean oil frying glutinous rice cake was the highest, followed by that frying wheat oil cake and yellow rice cake;the trend of the total oxidation value was basically the same as that of the p-anisidine value. The content of polar compounds in soybean oil of the three groups of glutinous rice cake, wheat oil cake and yellow rice cake exceeded national standard limit (≤27%) at 20, 18 h and 18 h, respectively, and the content of polar compounds in soybean oil frying yellow rice cake increased the most. The trans fatty acid content in soybean oil frying yellow rice cake was the highest, followed by that frying wheat oil cake and frying glutinous rice cake, which showed significant differences(p<0.05). In conclusion, traditional rice and flour foods made from glutinous rice, wheat and yellow rice have different effects on the quality of frying oil, and production adjustments should be made based on the specific effects of ingredients on the quality of oil during frying.
