摘　　要：以四层米糠、大豆粉、紫米粉、香菇粉、玉米粉、红薯粉、红枣粉为主要原料,利用线性规划法设计分层米糠代餐粉,以膳食纤维含量不低于总质量13%,且价格不得高于6元/份为主要约束条件,获得五种分层米糠代餐粉配方。通过对分层米糠代餐粉进行感官评价、水合特性以及自由基清除率比较,进一步确定了最优配方。结果表明,最优配方各成分含量为米糠1#30 g、米糠2#30 g、米糠3#98.68 g、米糠4#34 g、大豆粉22 g、紫米粉26 g、香菇粉14 g、玉米粉10 g、红薯粉18 g、红枣粉30 g,分层米糠代餐粉膳食纤维含量为16.03%,感官评分80分。在25和100℃时,代餐粉吸水指数为:1.07和1.19;水溶性为:68.46%和71.22%;膨胀势为:3.38和4.15;DPPH和ABTS+的自由基清除率为42.59%和57.52%。该分层米糠代餐粉具有较高的膳食纤维含量和较强的抗氧化活性。With four layers of rice bran, soybean powder, purple rice powder, mushroom powder, corn powder, sweet potato powder and red date powder as the main raw materials, the linear programming method was used to design the layered rice bran meal replacement powder. Five kinds of layered rice bran meal replacement powder formulations were obtained under the main constraint that the dietary fiber content was not less than 13% of the total quality, and the price was not higher than six yuan/share. The optimal formulation was further determined by sensory evaluation, hydration characteristics and comparison of free radical clearance. Results showed that: The optimal formula contained rice bran 1# 30 g, rice bran 2# 30 g,rice bran 3# 98.68 g, rice bran 4# 34 g, soybean powder 22 g, purple rice powder 26 g, mushroom powder 14 g, corn powder 10 g, sweet potato powder 18 g, red jujube powder 30 g. The optimal formula had 16.03% dietary fiber content and sensory score of 80 points. At 25 and 100 ℃, the water absorption indexes of meal replacement powder were 1.07 and 1.19,water solubility were 68.46% and 71.22%, the expansion potential were 3.38 and 4.15. The free radical scavenging rates of DPPH and ABTS+ were 42.59% and 57.52%. The layered rice bran meal replacement powder had high dietary fiber content and strong antioxidant activity.
