摘要
目的 GB 2760—2014《食品安全国家标准食品添加剂使用标准》中明确二丁基羟基甲苯(BHT)、叔丁基羟基茴香醚(BHA)及特丁基对苯二酚(TBHQ)等抗氧化剂的限量值以油脂计,但GB 5009.32—2016《食品安全国家标准食品中9种抗氧化剂的测定》方法中没有给出熟制坚果与籽类食品提取油脂的前处理过程和步骤。因此,考察样品粉碎和去壳与否对抗氧化剂测定结果的影响,并调查熟制坚果和籽类食品中抗氧化剂添加现状。方法以GB 5009.229—2016《食品安全国家标准食品中酸价的测定》中规定的油脂提取方式对葵花籽和花生进行油脂提取,考察样品去壳、带壳以及粉碎与否对TBHQ测定结果的影响。结果葵花籽和花生中TBHQ的检出率分别高达67.6%和30.6%,样品粉碎对TBHQ的提取效果更好,且带壳提取与去壳提取测定结果一致。结论测定熟制坚果与籽类食品时,采用GB 5009.229—2016中的方法提取油脂,其TBHQ的测定结果与样品是否粉碎有关,与样品是否带皮提取无关。
Objective The national standard,GB 2760—2014 Standard for the Use of Food Additives in National Standards for Food Safety,specifies that the limit values of antioxidants such as dibutylhydroxytoluene( BHT),tert-butyl hydroxyanisole( BHA) and tert-butyl hydroquinone( TBHQ) are calculated as oils and fats,but no pretreatment process and steps of oil extraction of cooked nuts and seed foods are available in the national standard GB 5009. 32—2016 National Standards for Food Safety Determination of 9 Antioxidants in Foods. Therefore,the influence of sample crushing and shelling on the results of antioxidant determination was investigated,and the current situation of antioxidant addition in cooked nuts and seed foods was investigated. Methods Sunflower seeds and peanuts were extracted by oil extraction method specified in GB 5009. 229—2016 Determination of Acid Value in Food Safety National Standard,and the effects of shelling,shelling and crushing on TBHQ determination results were investigated. Results The detection rates of TBHQ in sunflower seeds and peanuts were as high as67. 6% and 30. 6%,respectively. The extraction effect of TBHQ by crushing samples was better,and the results of extraction with shell and extraction without shell were consistent. Conclusion When determining cooked nuts and seeds,the method of GB 5009. 229—2016 is used to extract oil,and the TBHQ determination results are related to whether the samples are crushed or not,and have nothing to do with whether the samples are extracted with skin.
