Abstract:

A new way with compressed nata de coco to concentrate coconut milk was studied in this article. The experiment indicated that the optimal technology is as follows: the standard size of nata de coco is 1.5 cm × 1.5 cm × 1.5 cm, the compression ratio of nata de coco is 0.3, the ratio of compressed nata de coco and coconut milk is 1:3 (W/W), low speed mixing at normal temperature for 30 min. Under the above conditions, when the initial dry material content of coconut milk is 39.03%, after concentration its dry material content reaches 72.81%, the fat content is 66.88%, and the recovery of concentration coconut milk is 84.03%. Moreover, emulsified coconut milk to be concentrated by compressed nata de coco has better concentration effect than non-emulsified coconut milk, and the compressed nata de coco can be reused. After concentration, the by-product of coconut whey can be used as raw material in food industry.
