Eggs were immersed in the above extracts for 5 min , dried, sealed in bags and stored at 25 ℃and relativ e humidity 50% －70% . Th e qu ality of th e egg s was p eriodically ev alu ated by sen sory ev aluation and th e determination of some phy sicochemical indexes during storage. The results showed that honey suckle extract had th e b est fresh -k eep in g effect an d th e p ercen tage of fresh egg w as 100% after 35 d ay s o f st orage , w ith w eight losin g rate 2 .67%, yolk in dex 0 .358, th e content of den se album en 55.65%, Hau gh unit 50 .24 7 , and th e height of air chamber 2 .13 mm .
