摘要


本研究探討添加不同比例葡萄糖、蔗糖或奶粉等成分之燕麥產品,對以AOAC 995.16方法檢測其β-葡聚醣含量的影響,及其改善處理情形。檢體之β-葡聚醣檢測值依葡萄糖添加量增加隨之提高,添加5%以上葡萄糖者,其β-葡聚醣含量檢測值較未添加者高且有顯著差異。當添加葡萄糖於燕麥檢體之比例大於5%時,宜進行50%乙醇前處理後再測定β-葡聚醣含量,其檢測值相較於同添加量未經乙醇前處理者穩定且與原燕麥對照組相近。添加奶粉或蔗糖之燕麥檢體,其β-葡聚醣檢測值與未添加者均無統計差異。

The individual influence of glucose, sucrose and milk powder on the determination of β-glucan in oat products by the AOAC 995.16 method was studied. The absorption response increased as the glucose amount increased. The detected amounts of β-glucan in oat products had significant differences when more than 5% glucose was added. In this situation, pretreatment with 50% ethanol resulted in steadier data. Added sucrose or milk powder in oat products did not influence the determination of β-glucan.
