Process for making microwavable French fries
View Patent ↗A microwavable crinkle-cut French fry potato includes deep groves and coatings of oil and encapsulated salt. Crinkle-cut potato pieces are prepared with a solids content of 40–50% by weight, frozen, sprayed with oil and coated with encapsulated salt. A carton for the potato pieces is formed from a single-piece blank provided with a pair of microwave susceptor surfaces and reinforced corners. A removable lid contacts the potato pieces during microwave reconstitution.
1. A process for making elongated potato pieces adapted for microwave reconstitution comprising the steps of:
processing elongated potato pieces to a total solids in the range of 40 to 50% by weight;
freezing the elongated potato pieces;
applying oil to the frozen potato pieces, where the oil is solid at temperatures at and below 32° F. and is liquid at temperatures at and above 50° F.; and then
coating the frozen potato pieces with encapsulated salt so that the oil adheres the encapsulated salt to the potato pieces, where the encapsulated salt comprises 0.8 to 1.5% by weight of the potato pieces.
2. The process of claim 1 wherein the elongated potato pieces are processed to a total solids of 42.5% by weight.
3. The process of claim 1 further including the step of packaging the elongated potato pieces in a carton having two microwave susceptor surfaces.
4. The process of claim 1 wherein the step of applying oil to the frozen potato pieces applies a coating of about 1% by weight of oil.
5. The process of claim 4 wherein the step of applying oil includes the steps of:
tumbling frozen potato pieces; and
spraying the tumbling potato pieces with soybean oil.
6. The process of claim 1 wherein the processing to a solids content in the range of 40 to 50% by weight includes the steps of:
blanching the potato pieces;
drying the potato pieces to reduce the solids content by 10 to 15 weight percent;
parfrying the dried potato pieces at a temperature in the range of 330 to 360° F.;
equilibrating the parfried potato pieces; and
parfrying the equilibrated potato pieces at a temperature in the range of 375 to 395° F.
7. The process of claim 6 wherein the parfry steps are oil parfry steps.
8. The process of claim 1 including the step of providing elongated potato pieces having crinkle-cut longitudinal surfaces.
