My husband worked in the food industry for over 20 years. He said many of the generics are the same food stock, just put in private labels. Not all is that way - many are a second cut of product - not top quality. He knows when the fresh peaches are fresh and when they have been frozen. He knows which brands are first quality and which are second cut. He saves us a ton of money buying groceries because he knows the quality of the products. Sorry I can't give specifics - he has all that knowledge in his head!
