【摘要】 本文对猪油与菜油、棕榈油与菜油、乌桕油与菜油以及猪油为原料的定向酯交换法生产人造奶油、起酥油中间试验产品,交酯油的稠度进行了研究.作者按照IUPAC中熔化膨胀法,测定了55个试样的熔化膨胀度;然后把必要的值换算成SFC,并做出了SFC曲线.结果表明:经酯交换反应的油脂——交酯油,普遍加宽了塑性范围,同时说明了根据配方要求,可与其它油脂进行不同比例配合,制成令人满意的油脂产品.该法准确可行,有一定的工业应用价值.更多还原

【Abstract】 This paper describes the studies on consistency of directed interesterified oil in medium scale production test for producing margarine and shortening by directed interesterification method with lard and rapeseed oil, palm oil and rapeseed oil, chinese vegetable tallow and rapeseed oil, as well as lard itself. According to the melting dilatometric method in IUPAC method the author determined the melting dilateney of 55 samples. Then the necessary values were conversted into SFC, and are drawn into solid fat curves (SFC). The results indicated that the interesterified oil has a wide range of plasticity and can be blended with other oils to produce a kind of oil with satisfactory consistency. This method is workable and can be used in industry.更多还原
