摘　　要：在实验室小试的基础上,进行了水酶法提取花生油与水解蛋白的中试研究。采用三相分离机分离酶解产物的游离油、油水混合物和不溶残渣,再使用碟片分离机进一步将油水混合物分离为游离油、乳状液和水解液。采用冷冻解冻法对乳状液进行破乳,破乳率为81.18%。水解液经喷雾干燥后得到花生水解蛋白粉。最终总游离油得率为73.77%,水解蛋白得率为55.10%,为工业化生产提供了可靠的工艺参数。The pilot-scale study on aqueous enzymatic extraction of oil and protein hydrolysates from peanut was introduced in this article. The three-phase separator was chosen to separate oil, oil-water mixture and insoluble residue simultaneously. Then oil-water mixture was treated by the disk separator. We chose the freeze thawing method to demulsify the emulsion, and the demulsification efficiency was 81.18%. The peanut protein hydrolysates powder was obtained after the hydrolysates solution being spray dried. The total yields of free oil and protein hydrolysates were 73.77% and 55.10% respectively. After the pilot test, the reliable parameters suitable for the industrialization were provided .
