文摘
- •
Blends of soybean oil and fully hydrogenated soybean oil were interesterified by means of two sn-1,3 specific lipases.
- •
The effect of different reaction variables over acyl migration was studied.
- •
Lipozyme TL IM was proven to enhance acyl migration compared to Lipozyme RM IM.
- •
An increase in immobilized enzyme concentration promoted the acyl migration reaction.
- •
Unsaturated acyl moieties migrated faster defining a higher [1,3-DAG] at equilibrium.
