The present invention includes a process for producing substantially stable produce, typically vegetables and fruit that can be stored in a refrigerated environment for at least about five weeks without preservatives and at least about three months with preservatives. The process involves holding the produce in an aqueous immersion solution that includes a cellular stabilizing agent for a time sufficient to convert the produce into a heat durable piece and thermally processing the heat durable produce in the immersion solution. The use of additional ingredients as components of the immersion solution such as sweeteners, acids, salt, and preservatives are optional.
