Abstract:

The aim of the present study was to investigate the optimal spray-drying microencapsulation procedure of tilapia oil in a matrix composed of laboratory-made microporous cassava starch and collagen protein from tilapia skin using orthogonal array design. Results showed that the optimal emulsifying conditions of tilapia oil for achieving a minimum HLB value were as follows: emulsifying temperature 55℃, pH 6.0, and homogenization duration 6 min, and a maximum embedding efficiency of 92.1% could be obtained under the following optimal conditions: ratio of core material to wall material 1: 1.5, emulsifier amount 0.15%, solid substance content 20%, and air inlet temperature 180 ℃.

Key words: tilapia oil, microporous cassava starch, microencapsulation, spray drying
