Amylopectin potato flakes or granules and their use in snack foods
View Patent ↗Snack foods are prepared, at least in part, from potato flakes and/or potato granules which are derivable from potatoes in which the starch has a higher than normal amylopectin content, for example, waxy potatoes. The snack foods have improved texture and appearance.
1. A snack food having a high amylopectin content comprising potato flakes and/or potato granules, wherein 100% of the flakes and/or granules are prepared from potato of which the starch has an amylopectin content of at least 95 wt %,
wherein at least 50% by weight of the snack food is the flakes and/or granules prepared from potato of which the starch has an amylopectin content of at least 95 wt %, wherein dough of the snack food comprises the flakes and/or granules,
and wherein the snack food comprising flakes and/or granules prepared from potato of which the starch has an amylopectin content of at least 95 wt % becomes more expanded upon cooking than a snack food comprising potato flakes and/or granules prepared from potato of which the starch has a normal amylopectin content of about 80±3 wt %.
2. A snack food according to claim 1 , wherein the high amylopectin potato content is substantially all in the form of potato flakes.
3. A snack food according to claim 1 , further comprising potato flakes and/or other potato dehydrates prepared from potato of which the starch has a normal amylopectin content of about 80±3 wt %.
4. A snack food according to claim 1 , further comprising one or more cereal flours.
5. A snack food according to claim 1 , further comprising one or more additives typically used in snack food manufacture.
6. A snack food according to claim 1 , wherein the snack food is a fried snack food.

8. A snack food according to claim 1 , wherein the snack food is an extruded snack food.
9. A snack food according to claim 1 , further comprising an isolated starch.
10. A snack food according to claim 9 , wherein the isolated starch is a waxy starch.
11. A snack food according to claim 10 , wherein the waxy starch is a pregelatinised waxy starch.
12. A snack food according to claim 11 , wherein not more than 25% by weight of the snack food is pregelatinised waxy potato starch.
13. A snack food according to claim 12 , wherein not more than 10% by weight of the snack food is pregelatinised waxy potato starch.
14. A snack food according to claim 1 , wherein the potato flakes and/or granules, prepared from potato of which the starch has a amylopectin content of at least 95 wt %, are from a genetically modified potato plant.
15. A snack food according to claim 14 , wherein the modified potato plant is derived from a Saturna variety.
16. A snack food according to claim 1 , wherein the potato flakes and/or granules, comprising starch with a high amylopectin content, are from potatoes having not more than 5% by dry weight of reducing sugars.
17. A snack food according to claim 1 , further comprising an oil and/or an emulsifier.
