摘要

本研究旨在评估小麦麸皮(WB)粒度分布的质量特征,并评估农民的排名与实验室结果的一致性。30名小奶农从埃塞俄比亚提格雷的5家主要小麦粉加工厂对5种WB类型进行了定性评分,其持水能力(WHC)和营养价值(1 =差至4 =优)以及消化系统紊乱风险(1 =高至4 =极低)的评分范围为1至4。实验室分析包括物理参数、化学分析和体外消化率。WB的几何平均粒径(D50)在908 ~ 1103 μm之间,WHC在2.15 ~ 2.90 ml/g之间。农民营养价值评分与粗蛋白质呈正相关(rspearman’s = 0.347;p

Bridging farmers' perceptions and laboratory science: wheat bran quality assessment in smallholder dairy systems: technical note.

This study was conducted to evaluate wheat bran (WB) quality characteristics based on particle size distribution and to assess how farmers' rankings align with laboratory results. Thirty smallholder dairy farmers qualitatively scored five WB types from five major wheat flour processing factories in Tigray, Ethiopia, on a scale of 1 to 4 for water holding capacity (WHC) and nutritive value (1 = poor to 4 = excellent), as well as the risk of digestive disorders (1 = high to 4 = very low). Laboratory analyses included physical parameters, chemical analysis, and in vitro digestibility. The geometric mean particle size of WB ranged between 908 to 1,103 μm, and the WHC between 2.15 to 2.90 mL/g. Farmers' scores for nutritive value correlated positively with crude protein (rspearman's = 0.347; p<0.05) and effective rumen degradability of crude protein (rspearman's = 0.291; p<0.05), and negatively with particle size (rspearman's = -0.553; p<0.05). Scores for WHC positively correlated with particle size (rspearman's = 0.526; p<0.05). The present findings revealed that particle size distribution is the predominant qualitative selection criteria for farmers (e.g., on the market) to assess WB quality, and this qualitative appreciation is to some extent related to chemical characteristics and rumen degradability.
