PROBLEM TO BE SOLVED: To efficiently prevent the dehardening of vegetables without impairing natural palate feeling and gustatoriness inherent therein by impregnating them with a highly concentrated saccharide (alcohol) solution followed by heating or freezing treatment. SOLUTION: Vegetables such as carrot, tomatoes or onions are impregnated with a saccharide (alcohol) solution (such as of glucose or sorbitol) of >=50wt.% in concentration e.g. at <=40 deg.C followed by conducting a heating or freezing treatment, thus preventing the vegetables from dehardening. It is preferable that the above solution be an aqueous solution containing the saccharide (alcohol) and an organic acid such as acetic acid and has a pH of 1.8-3.5). |
