the hydrolysis method by using enzyme was developed to degrade corn starch into fine particles suitable for using as fat mimetics. Dextrozyme was identified from four possible hydrolytic enzymes as the most effective enzyme for this purpose. The particle sizes of the starches produced were significantly smaller than those without treatment, with size distribution mainly being around 2–4 μm. The hydrolysed starch was then added to produce low fat mayonnaise and the result indicated that the 60% fat-reduced mayonnaise with fat mimetics had similar sensory quality as compared with the high fat one.
