摘要
对核桃渣中油脂和蛋白质进行了水剂法同步提取分离工艺研究。经单因素实验,获得了适宜的工艺条件为:兑水pH 11.5,料液比(g∶ml)1∶8,浸提温度50℃和浸提时间5 h。在此条件下,油脂得率为26.05%,蛋白质得率为10.72%。工艺过程中采用冻融法破乳增加油脂得率,破乳后的清油Ⅱ平均得率为43.05%以上。
Aqueous synchronous extraction of oil and protein from walnut milk residues was investigated.Through single factor experiment,the best process conditions was: pH 11.5,ratio of solid to liquid 1∶8,lixiviated at 50℃ for 5h.Under the above conditions,the oil yield was 26.05%,the protein yield was 10.72%.Freezing and thawing demulsification was used to increased oil yield.The average yield of the free oilⅡ after demulsification was 43.05%.
