摘  要:
热处理大豆是加工饲用全脂大豆的新技术。该文以生大豆及传统的膨化大豆作对照,探讨不同加工方法全脂大豆脲酶活力、KOH氮溶指数、油脂稳定性以及产品贮藏过程中过氧化值(POV)的变化。结果表明同膨化工艺相比,热处理大豆的贮藏稳定性好于膨化大豆,KOH氮溶指数和脲酶活性均达到饲用要求。肉鸡饲养试验表明,在相同的营养水平下,热处理全脂大豆,膨化大豆与豆粕+油脂3种日粮配方对0~21日龄肉仔鸡的生长速率、饲料转化率无显著性差异。

摘  要:
Steam processing is one kind of new technology to process full fat soybean. The Urea activity, index of KOH protein solubility, oil stability, and Peroxide Value of the processed soy products with different process technology were determined. It was indicated Urea activity and Index of KOH protein solubility for steam processed full fat soy bean( SPFFSB)were qualified as feed ingredient. Compared with extruded full fat soy bean (EFFSB), the oil of SPFFSB was more stable during storage. Feeding trial with 0-21 days broiler indicated that the growth rate and feed conversion were no significantly different between EFFSB, SPFFSB, and soy bean meal with soy oil feed separately.
