Many food items have been shrinking as companies try to make up for higher ingredient costs. The companies are also raising prices, but making products smaller gives them another way to make up the difference. At the same time, though, customers are getting less food – and they’re not paying any less.

Here’s a look at how some big-name products are shrinking:

Cereals: In June, Kellogg Co. said it was shrinking, by an average of 2.4 ounces, the packages of 14 items sold under the brands Apple Jacks, Cocoa Krispies, Corn Pops, Froot Loops and Honey Smacks. Rival General Mills Inc. more than a year ago shrank some of its boxes, including Cinnamon Toast Crunch and Trix.

Orange juice: Large jugs by Tropicana are now 89 ounces, down from 96 ounces. The company is part of the PepsiCo Inc. family of products.

Peanut Butter: The Skippy brand, made by Unilever, now sells in packages of 16.3 ounces, down from 18 ounces.

Deli Meats: Some packages of Hillshire Farms deli meats, made by Sara Lee Corp. are now in 9-ounce tubs, down from 10 ounces.

Mayonnaise: Certain Jars of Hellmann’s, also by Unilever, are now 30 ounces rather than 32 ounces.

Margarine: Some Country Crock tubs, by Unilever as well, are now 45 ounces, down from 48.

Ice Cream: Certain packages of Breyers, also made by Unilever, and Edy’s, by Dreyer’s Grand Ice Cream Holdings Inc., are now selling in 48 ounce cartons, down from 56 ounces.

Chocolate: Mars Inc. plans to decrease the volume of some of its package types. It makes Snickers bars and M&M; candies, among other brands, and hasn’t announced specifics.

Gum: Wm. Wrigley Jr. Co. now sells brands like Juicy Fruit, Big Red, Doublemint and Winterfresh in 15-stick packages, down from 17.
