Abstract: The present invention relates generally to processing of viscous food products such as full-fat, reduced-fat, light or fat-free viscous salad dressings, and reduced-fat, light or fat-free mayonnaise. More particularly, the present invention relates to viscous salad dressings and reduced-fat mayonnaise and methods of making the viscous salad dressings or reduced-fat mayonnaise which are streamlined and are limited to addition of the ingredients to a single mixing apparatus (i.e., a one-pot preparation). Furthermore, the present invention relates to simplified methods of making such viscous dressing products. The present methods are streamlined and do not require the preparation of a separate cooked starch base. This invention also relates to viscous dressing products prepared by the methods provided herein. The organoleptic and sensory properties of the present viscous dressings are similar to those found in conventionally prepared viscous dressings.
