Thermally processed fruits and vegetables are softer in texture than fresh. It is challenging to obtain acceptable texture from thermally processed IQF fruits and vegetables. The soaking method of the invention enhances the texture of high quality IQF fruits and vegetables before thermal processing resulting in a processed, shelf-stable fruit or vegetable product with significantly improved texture. When compared to other traditional firming methods using calcium salts added directly to the pack medium or finished product, or using a food enzyme, such as pectinmethylesterase (PME), the soaking method yields fruit and vegetable products with significantly better post-cook textures. Using this method will also enable manufacturers of shelf-stable fruit and vegetable products to use IQF ingredients in continuous year-round production.
