1. A process for treating fruit or vegetable material to minimize loss of texture which comprises contacting said material for a period of time sufficient to stabilize the texture of said material at a temperature of about 0°
- C. to 75°
C. with at least 0.1 percent by weight based on the weight of said materials being treated of an organic compound selected from the group consisting of;
(a) alcohols,(b) aldehydes,(c) amides,(d) esters,(e) hydrocarbons,(f) halogenated hydrocarbons,(g) ketones,(h) lactones and(i) nitriles,rinsing the fruit or vegetable material with water or a water-based medium to remove the major portion of said organic compound and heating the rinsed material at temperatures of at least 80°
C. for a sufficient period of time to effect sterilization of the material.

Abstract
Loss of texture in vegetable and fruit material caused by heating such material in connection with the preservation thereof can be minimized by contacting the fresh vegetable and fruit material with certain organic compounds for a short period of time and then removing the organic compound by rinsing the material with water or a water-based medium prior to heating the vegetable and fruit material.
