摘　　要：对粗制鹅油进行精炼加工,探讨鹅油精炼的最优方法和条件,为生产出符合国家标准要求的鹅油提供参考。该文对粗制鹅油进行精炼,采用单因素结合响应面优化精炼工艺条件,并对所得精炼鹅油进行理化指标的测定。结果表明:以100 g粗鹅油为基准,磷酸浓度55%、活性白土用量1.2 g、脱胶温度65℃、脱臭时间10 min,在此条件下,获得的鹅油提取率为93.11%,鹅油酸价为(1.45±0.23)mg/g,过氧化值为(0.093±0.036)g/100 g,皂化值为(144.56±0.68)mg/g,水分含量为(3.92±0.089)%,相对密度为0.98±0.01。通过响应面法优化鹅油精炼工艺后所得的鹅油不仅提取率高,且理化指标符合国家标准要求。Refining and processing crude goose oil,exploring the optimal method and conditions for refining goose oil to provide a reference for the production of goose oil that meets the requirements of national standards.In this paper,the crude goose oil was refined,the single-factor method combined with the response surface method were used to optimize the refining process conditions,and the physical and chemical indexes of the obtained refined goose oil were determined.Results showed:based on 100 g crude goose oil,the concentration of phosphoric acid 55%,the amount of active bleaching clay 1.2 g,the degumming temperature 65℃,and the deodorization time 10 min,under these conditions,the extraction rate of goose oil was 93.11%,the acid value of goose oil was(1.45±0.23)mg/g,the peroxide value was(0.093±0.036)g/100 g,the saponification value was(144.56±0.68)mg/g,the moisture content was(3.92±0.089)%,and the relative density was 0.98±0.01.Through optimizing the refining process of goose oil by the response surface method,the obtained goose fat not only had a high extraction rate,but also its physical and chemical indexes all met the requirements of national standards.
