The roles of oil, hexanal and sucrose were investigated in colour development and HMF formation during roasting of hazelnuts.The highest HMF levels and the deepest browning extension were in crushed hazelnuts and the lowest HMF and browning were indefatted or partially defatted samples. The addition of hexanal, at 175 C, increased the HMF level. This was particularly evident insamples with sucrose. Moreover samples totally reintegrated in oil did not reach (after roasting) the same HMF level and colour asthe corresponding crushed samples.

Abstract
The roles of oil, hexanal and sucrose were investigated in colour development and HMF formation during roasting of hazelnuts.The highest HMF levels and the deepest browning extension were in crushed hazelnuts and the lowest HMF and browning were indefatted or partially defatted samples. The addition of hexanal, at 175 C, increased the HMF level. This was particularly evident insamples with sucrose. Moreover samples totally reintegrated in oil did not reach (after roasting) the same HMF level and colour asthe corresponding crushed samples.File in questo prodotto:
