Ingredient, in-process, environmental, shelf life and end product tests vary in relative importance for the different product types considered. This chapter covers mayonnaise, dressings, mayonnaise-based salads, margarine, butter, reduced-fat spreads, water-continuous spreads and miscellaneous products. Specific recommendations and sampling plans are provided, where appropriate.
