Optimization on Technology of Peony Seed Oil-Loquat Juice Hydrogel Bursting Beads
In order to effectively utilize peony seed oil and loquat,peony seed oil and loquat juice were used as core materials,and the cross-linking reaction of sodium alginate and calcium lactate was used to prepare peony seed oil-loquat juice bursting beads.Single factor experiments were conducted to study the effects of five main factors on the texture of bursting beads:the concentration of sodium alginate-low ester pectin complex solution,the addition of calcium lactate,the addition of xanthan gum,pellet forming reaction time and the concentration of chitosan curing solution.On this basis,an orthogonal experiment was used to optimize the pellet forming process formula of bursting beads.The amount of peony seed oil and peppermint flavor was determined by sensory score,so as to optimize the best flavor formula of peony seed oil-loquat juice bursting beads.The results showed that the best technology and formula for preparing bursting beads were:the concentration of sodium alginate and low ester pectin composite solution was 1.2％(w/w),calcium lactate was 1.9％(w/w),xanthan gum was 0.8％(w/w),pelleting reaction time was 10 min,the concentration of chitosan curing solution was 0.1％(w/w),and the amount of peony seed oil was 1.0％(w/w),the content of peppermint flavor was 1.1％(w/w)and loquat juice was 95.2％(w/w).The peony seed oil-loquat juice bursting beads made under these conditions has good texture,light yellow appearance,round and full,and bursting sensation during chewing.
