Development of new rose petal jam

In this paper,rose petals and rose essence were used as additive to develop a new type rose petal jam.The optimum levels of process conditions were determined by using single factor method and orthogonal array desing,and the best dilution proportion of alcohol adding to rose essence was researched.Results showed that the optimum formula included rose petals(dry) 3%,sugar 54%,xanthan gum 0.2%,rose essence 0.17%,finally heating time 30 min.The rose jam followed this formula tastes very good.
