Optimization of Formula and Antioxidant Research on Throat-clearing Candy
Intended to used exocarpium citri grandis,apricot kernel,platycodon grandiflorum,job's tears,liquorice,rock sugar and maltose as raw materials to prepare throat-clearing candy.The best proportion of five herbs was obtained by antimi-crobial and response surface test.Using sensory scores as evaluation indicators,obtained the optimal formula through mixed design experiments.The results showed that the best antibacterial effect was achieved when exocarpium citri grandis 25 g,se-men coicis 40 g,almond 5 g,platycodon grandiflorum 7 g,liquorice 5 g were used together.The optimal formula was herbal extract 22.7％,maltose 19.9％,rock sugar 57.4％.The total flavonoid content was(0.657±0.010)mg/g,it had a good scavenging effect on DPPH and ABTS+radicals.The reducing sugar content was(18.75±0.07)g/100 g.The drying loss rate was(3.72±0.08)g/100 g.The throat-clearing candy was rich in flavonoid active ingredients and had good antioxidant activi-ty.It met the requirements of relevant national standards.
