New York — Specialty food retailers have had greater growth in store brand product sales between 2005 and 2009 than other channels, according to a report.

Compound annual growth of the items in traditional grocers was reported at four percent from 2005 to 2009, according to researcher Packaged Facts. Comparatively, sales of store brands through specialty grocers Whole Foods Market and Trader Joe’s grew 14 percent during the same period, the company finds. Supercenters posted annual growth of nine percent while club stores registered six percent growth and discount supermarkets sales of store brands grew two percent through the five-year period.

Packaged Facts estimates private label food and beverage dollar sales totaled $89 billion in 2009, some 17 percent of total food and beverage retail sales in the U.S., and a six percent increase from the year prior.
