ABSTRACT

Meatsticks (MS; beef, pork) or stewsticks (SS; beef, pork, vegetables) were formulated to pH 5.2 or 4.6 with encapsulated lactic or citric acid. Stewsticks had 18% less fat and calories/serving than MS, and substantially more carbohydrate and vitamins A and C, but were much drier after cooking. Meatsticks were preferred, although 25% of consumer panelists rated SS as moderately acceptable or higher on a 9-point hedonic scale. Acid type (citric or lactic) did not affect consumer panel flavor scores, but samples at pH 4.6 were only marginally acceptable. Acidification to pH 4.6, as might be required according to regulations for hermetically sealed, low acid foods, would greatly decrease commercial appeal of these products.
