Compiled By Deborah Austin Consumers wield unprecedented clout in the food industry, and manufacturers and retailers rushing to deliver powerful brands will face increased consolidation/internationalization over the next half-decade -- suggests a report by global management/information-technology consulting firm Cap Gemini Ernst & Young. Twenty to 25 global consumer-goods brands owned by about 10 brand manufacturers will take leadership in more than 100 nations, says the report, "State of the Art in Food: The Changing Face of the Food Industry." Manufacturers also will "marry" global brands with "local jewels" to meet consumers' burgeoning local-product demand. With better supply-chain integration, retailers and manufacturers in Europe could see cost savings of 8 billion euro by 2010; in the U.S., up to $7 billion. But current lack of collaboration will hamper such cost savings.
