High pressure homogenisation at 50 MPa or higher could double the amount of bioaccessible b-carotene by disintegrating cell clusters and disrupting cells which facilitates the release of b-carotene during digestion. Fortunately, this increase in in vitro bioaccessibility was not accompanied by an increase in b-carotene degradation or isomerisation. When high pressure homogenisation was followed by a thermal pasteurisation process, the in vitro b-carotene bioaccessibility wasimproved further. The high temperature could weaken the physical barriers that enclose b-carotene, which results in a facilitated
