摘要
通过近2年的跟踪试验,研究葵花籽原料及不同月份生产的成品随常温贮存过程的过氧化值变化状况。试验结果表明:GB19300规定的熟制葵花籽产品过氧化值≤0.50(g/100g脂肪),在产品货架期内极易超标。而当过氧化值达1.1(g/100g脂肪)时,产品仍符合酸价和感官质量指标的要求,并能被消费者接受。根据过氧化值试验结果分析,建议将熟制葵花籽产品过氧化值指标修订为≤1.0(g/100g脂肪)。
In two years,the variations of peroxide values for the raw materials and the different month produced products of roasted sunflower seed,stored at room temperature,were investigated.The results showed that during the shelf life,a large percentage of products had levels exceeding GB19300＇s standard for the peroxide value（≤ 0.50 g/100 g fat）.Both sensory qualities and acid values still met the requirements of the products,and the products were acceptable to consumers when peroxide value reached 1.1.According to the analyses of peroxide value,it is recommended that the standard for peroxide value of roasted sunflower seed products should be revised to not more than 1.0（g/100 g fat）.
