<p>PURPOSE:To preserve a potato in an immediately cookable state without deteriorating the taste, flavor and quality of potato by sterilizing a skinned and washed potato with a hot organic acid and packaging in vacuum. CONSTITUTION:Skinned, trimmed and washed potato is sterilized for a short time (about 3-10sec) in an aqueous solution of an organic acid and/or organic acid salt heated at 80-98 deg.C. The solution is e.g. 0.5-5wt.% aqueous solution of one or more components such as ascorbic acid, sodium ascorbate and sodium citrate. The sterilized potato is packed with a film having an oxygen- permeability of <=100cc/m<2>.24hrs.atm (at 23 deg.C) in vacuum of 100mmHg and preserved at 0-10 deg.C.</p> |
