Reducing food waste is the important way to ensure food security.Household is the basic unit of society.Household is not only the main scene of food waste,but also an important place to carry out anti-food waste education.This study takes Zhengzhou city,Henan province as an example,based on 1315 first-hand survey data of urban household food waste,and di-vides such waste into two parts:food waste inside three meals and outside three meals during a day.It studies the overall situation of urban household food waste,household food waste behav-ior and its influencing factors,and proposes targeted reduction strategies on this basis.The re-sults show that:(1)The per capita per day food waste of urban households was 15.47 g/d,of which vegetables account for 47.45％of the total,followed by staple foods(20.51％),and meat(13.41％).(2)There were significant differences in the amount and composition of per capita per day food waste inside and outside the three meals.The per capita per day food waste inside the three meals was 10.70 g/d,2.24 times of that outside the three meals;vegetables(55.39％),staple foods(20.80％),and meat(18.72％)account for the largest proportion of waste inside the three meals,while vegetables(29.65％),milk(25.68％),and fruits(21.67％)account for the largest proportion of waste outside the three meals.(3)Reducing household food waste should focus on modifiable factors.Controlling the frequency of ordering takeout,increasing informa-tion intervention,and improving level of food waste awareness and household food manage-ment ability are the main strategies to reduce food waste in urban households.
