| 为了明确花生品种对水酶法制油的影响，测定了不同品种花生（豫花23、豫花37、豫花9326）的基本成分，并研究了水酶法制油工艺条件对不同品种花生水相体系中油脂和蛋白质分布的影响。结果表明：3个花生品种中，豫花37的油脂、水分、灰分、可溶性糖、可溶性总酚含量均最高，豫花23的蛋白质含量最高（25.36%），豫花9326的粗纤维含量最高（6.59%）；花生品种对水相体系中油脂和蛋白质的分布有显著影响；以水相体系中低油脂和高蛋白质分布为准则得到水酶法制油的最佳工艺条件为豫花37的粉碎时间90 s、豫花23和豫花9326的粉碎时间120 s，酶用量1.0%，酶解时间2 h，酶解温度50 ℃，此时豫花23、豫花37、豫花9326在水相体系中油脂分布分别为6.21%、4.19%、4.19%，蛋白质分布分别为50.99%、75.68%、63.84%。综上，豫花37能在更短的粉碎时间内使水酶法制油过程中花生水相体系中的油脂分布少，蛋白质分布多，更适用于水酶法制油。 |
