Orthogonal Array Design for Optimizing the Use of Neutral Alumina Adsorbent to Reduce Cholesterol in Butte

doi:10.7506/spkx1002-6630-201224035

Abstract

Abstract:

This study aimed at establishing a physical adsorption method for removing cholesterol from butter. An orthogonal array design was used to determine optimum conditions for the adsorption of butter by neutral alumina. The results showed that 40% of the cholesterol in butter was removed when it was treated with 15% added neutral alumina at 65 ℃ for 1 h. Neutral alumina was found to be the best adsorbent for the removal of cholesterol from butter followed by acidic alumina, Si-Mg adsorbent, diatomite, arabic gum, xanthan gum, cyclodextrin and active alumina. Furthermore, neutral alumina had little impact on the quality of butter.

Key words: butter, cholesterol, adsorbent, removal rate
