性质描述: 白色针状结晶。熔点为161-162℃。易溶于热水、氯仿，溶于乙醇，微溶于乙醚和苯，不溶于石油醚。在碱溶液中呈黄色，与氧化铁作用成红紫色，对石蕊呈酸性反应。在93℃时升华成柱状体。
生产方法: 麦芽醇有三种主要制法1.从天然产物中提取 麦芽醇存在于小麦、大豆的分解液中和大麦焙烧凝缩物中，也存在于某些枞树和落叶松树皮层中。1986年美国就用萃取结晶法从木醋中提取麦芽醇。1970年美国又从落叶松树皮中用氯仿提取麦芽醇。日本从连香树（cercidiphyllumjaponicum）叶中用氯仿直接浸提或从其水蒸气蒸馏液中提取。从木材干馏所得的木焦油进行减压蒸馏也可分离到麦芽醇。2.半合成法（以曲酸为原料）曲酸（Kojic acid）的母体是葡萄糖，相当于3-酮-葡萄糖的脱水产物。将淀粉用黄曲霉菌发酵，在发酵液中产生的曲酸，经转变成曲酸把催化下用空气（或氧气）氧化成靠闷酸，然后在225℃下脱羧成焦袂康酸。在碱性条件下将焦袂康酸与甲醛反应，生成羟基麦芽醇。然后用盐酸和锌粉进行还原得麦芽醇。经蒸馏或升华，在氯仿中重结晶，即得麦芽醇成品。从曲酸制成靠闷酸，也可通过曲酸与氯化苄经醚化生成曲酸苄醚，再用二氧化锰氧化成靠闷酸醚，然后脱苄基生成靠闷酸。3.用糖醛为原料合成麦芽醇。
用途: 该品具有焦糖香，在稀溶液中有草莓香。麦芽醇是γ-吡喃酮的衍生物，主要作食品增香剂、日用品和烟用香料、感光材料、防腐剂和护肤药物。用微量麦芽醇加入食品中，不仅使香味有了改善和增浓，还能延长食品储存期而不发霉。用来调制日用品的香精，也能发挥出良好的调香效果。麦芽醇也是感光胶片涂布均匀防止斑点和条纹的极好物质。用其配制的护肤化妆品，有抑制黑色素生长，美白皮肤的良好效能。用于生产各种食品，如巧克力、糖果、罐头、果酒、果汁、冰激凌、饼干、面包、糕点、咖啡、汽水和冰糕等，一般用量为万分之一左右。它对食品的香味改善和增强具有显著的效果，对甜食起着增甜作用。一份麦芽醇可代替四份香豆素使用。每吨饲料中加入5-200g麦芽醇，有促进仔猪快速生长的作用。
