抄録

This work was undertaken to lock β-carotene into carbohydrate matrix, and the preservation stability of β-carotene in the matrix was also described.<BR>The mixture of 80% sucrose and 20% corn syrup solids (DE. 12) was dissolved into water by heating and the concentration of total soluble solid was adjusted from 80% to 90%. To the carbohydrate solution, 2% sugar ester (HLB. 15) and vegetable oil solution of β-carotene were added respectively, and then the mixture was stirred vigorously at 80-90°C. The mixture was dried in a vacuum drier at room temperature until 4% moisture level. The dried mixture was then ground and dried again in a vacuum drier at 60°C until below 1% moisture content. β-Carotene locked into carbohydrate matrix by this method was not transformed at room temperature for 6 months and for a month under 40°C incubation. Also β-carotene in the carbohydrate matrix was not extracted with such non-polar solvent as cyclohexane. By this procedure, β-carotene can be locked into carbohydrate matrix and also can be stabilized perfectly. The powdered β-carotene described here is apparently water-soluble and has long shelf-life.
