Abstract:

In this paper, the 6 main varieties of Chinese chestnut were used as test materials to comparing gelatinization characteristics of chestnut powder of different waxy varieties and the influence of de-fat, de-proteins on pasting properties of the chestnut powder. The results showed that: 1) The paste viscosity of high-waxy varieties was significantly lower than Low-waxy varieties (P<0.05). 2) After de-fat, chestnut powder RVA spectrum characteristics value did not apparently change, however after de-protein, chestnut powder pasting viscosity significantly increased, pasting temperature reduced. 3) A correlation analysis showed that: there were significant negative correlation(P<0.05) between the protein content and peak viscosity, through viscosity, breakdown, final viscosity as well as setback, no correlation was found between the fat content and chestnut powder gelatinization characteristics.

Key words: de-fat chestnut powder, de-protein chestnut powder, RVA characteristics
