1,190,624. Dehydrated potatoes. AMERICAN POTATO CO. 3 May, 1967 [3 May, 1966], No. 18254/67. Heading A2D. A process for producing a permeable dehydrated potato piece rapidly reconstitutable without loss of piece identity comprises (a) producing an aqueous dough having a 17-30% by wt. solids content, the solids content comprising not less than 80% by wt. undamaged separated potato cells, extra cellular starch including some gelatinised starch and comprising added raw starch (e.g. corn starch) in an amount not less than 6% by wt. of the total solids, and any desired additives (b) heating the dough to above 170‹F. to gelantinise the raw starch, (c) forming the dough into pieces (e.g. by extrusion) before or after step (b), (d) predrying said pieces substantially out of contact with one another to remove surface moisture to prevent them adhering to one another, and (e) finally drying at a rate to prevent case hardening, to a moisture content of about 7% by wt. The dough may comprise potato granules or flakes. The gelatinised starch may be produced in the production of the separated potato cells as a result of some of the cells breaking during a cooking step to give gelatinised starch. The additives may be antioxidants, sulphite salts, calcium salts and sugar. The starch may be gelatinised using steam. The pieces may be air dried. |
