Abstract

Candida rugosa lipase (LCR) was immobilized on low-cost supports (byproducts) and dried using a spouted-bed system. The yields of immobilized derivatives were in the range 61.5-78.7%. Lipase immobilized on rice husk showed the best results, presenting 94.1% of the original activity, followed by sugarcane bagasse (90.3%) and green coconut fiber (87.3%). Moisture content in the obtained powders varied between 4.7 and 5.6% and the water activities were in the range 0.21-0.35. Among all the tested biocatalysts for aroma production the lipase immobilized on rice husk showed the highest activity towards the formation of isoamyl caprylate (62.40 g.L-1). (AU)
