    摘要:

    将燕麦以不同比例添加到半干面中,测定半干面的菌落总数、脂肪酸值和质构特性,研究了燕麦对半干面储藏稳定性的影响。结果表明,随着储藏时间增加,半干面的菌落总数和脂肪酸值不断上升.随着燕麦添加量(质量分数)增加(10%,30%,50%,70%和100%),半干面菌落总数显著下降(P<0.05),初始脂肪酸值显著增加(P<0.05)。50%添加量时,货架期比对照组延长了29.4%;质构结果显示,30%以上添加量时,硬度和咀嚼性显著下降(P<0.05)。对燕麦籽粒进行真空微波处理,籽粒脂肪酸值和菌落总数分别降低44.9%和82.5%.与对照组相比,微波处理后,50%燕麦添加量制作的半干面,在储藏中脂肪酸值和菌落总数都显著降低(P<0.05),储藏48 h时,菌落总数降低了0.23 lg(CFU/g),脂肪酸值降低了57.7%,并且硬度和咀嚼性极显著增大(P<0.01),改善了燕麦半干面的储藏稳定性。

    Abstract:

    The text added different percentage of oats into semi-dried noodles.Our study focused on measuring its total plate count\free fat acids and textural property.and the effect of incorporation of oats on storage stability of semi-dried noodles. The results showed that the total plate count and free fat acids of oat semi-dried noodles increased during storage. With the increased percentage of oats(10%,30%,50%,70% and 100%),the total plate count of semi-dried noodles decreased significantly(P<0.05) and initial free fatty acids increased significantly(P<0.05). Compared with the control group,the shelf life was prolonged by 29.4% with 50% oat percentage. The textural property showed that hardness and chewiness decreased obviously(P<0.05) with higher oat percentage than 30%. The free fatty acids and total plate count of oat kernels decreased by 44.9% and 82.5% respectively after vacuum microwave treatment. Compared with the control group,the free fatty acids and total plate count of semi-dried noodles with 50% oat flour decreased significantly(P<0.05). The total plate count decreased by 0.23 lg CFU/g and free fatty acids decreased by 57.7%. The hardness and chewiness increased significantly(P<0.01),which indicated that treatment improved the storage stability of oat semi-dried noodles.
