Properties and Food Uses of Chestnut Flour and Starch

Abstract

This review summarised the compositional, thermal, and rheological properties and food applications of chestnut (Castanea spp.) flour systems. The compositional, structural, and physicochemical properties of chestnut starch, which is a major determinant for product quality, were also reviewed. Future research directions on how to better utilise chestnut flour and starch for food product developments were suggested. Chestnuts are important food items for many people around the world. The world production of chestnuts has kept increasing during the last decade. There has been growing interest to utilise chestnut flour for various food applications (e.g. gluten-free food products). The major component of chestnut is starch which amounts to over 50% of the dry weight of the fruit. Chestnut starch may as well have potential for food and non-food applications. Overall, this review provides a scientific basis to develop chestnuts as sustainable and cash crops.
