Effects of Popping on Nutrient Contents of Amaranth Seed

Plant Foods for Human Nutrition volume 69, pages 25–29 (2014)Cite this article

Abstract

Amaranth seeds can be popped by heating. The traditional method of popping in a skillet is simple, but it is difficult to control the heating time and temperature. To overcome these disadvantages, we developed a fluidized bed continuous processing system based on hot air heating for producing popped amaranth seeds in bulk. Using this system, we evaluated the effects of heat treatment at 260 °C for 15 s on the contents of B-group vitamins and essential and trace elements in amaranth seeds. The results showed that the treatment did not affect the content of B-group vitamins, and the recovery for essential and trace elements was 97–196 %. This popping system is useful for processing amaranth seeds in terms of the product quality and nutrition.
