The caloric value of the LF mayonnaise wassignificantly (P≤0.05) reduced by increasing thelevel of fat substitution. The LF mayonnaiseprepared with sunflower oil or soybean oil at 45%level showed the lowest (P≤0.05) caloric valuesamong all mayonnaise formulations. The reductionin caloric values could be attributed to thesubstitution of oil in FF mayonnaise with waterand hydrocolloid gums (non-caloric ingredientsbecause they are not digested or absorbed in thehuman digestive tract) in LF mayonnaise. Water isconsidered a key component when replacing fatusing a carbohydrate based fat replacer. Waterforms a gel like structure with the hydrocolloid
gum, which enhances the texture of the LF
mayonnaise.
