摘要：Today, "conscious consumers" pay attention not only to the quality characteristics of the fruits they buy, but also absence of chemical remnants on them. In this study, the effect of ^bagging'" treatment which prevents drugs from touching fruits on some properties of apple fruit was investigated. For this purpose, The fruits on the Red Chief apple fruit grafted to MM.106 rootstock were covered one by one by lock ziplock bags and paper bags. In the scope of the study, the effect of bagging treatment on the pomological properties, sugar composition, antioxidant activity and residue level of the fruits was determined. Within the scope of the experiment, the effect of the treatments of the ziplock bag and paper bag on the pomological properties such as fruit weight, width, length, number of seeds and weight, fruit petiole length and thickness was found to be insignificant. However, the effect of bagged fruits on soluble solids content (SSC), fruit flesh firmness, pH, color L*, b*, hue and chroma was different compared to the control fruits. In both bagging treatments, the soluble solids content value of fruit juice was found higher than control fruits. The L*, b* and chroma values of the fruits were found higher than the fruits covered with ziplock bag and paper bag. However, Hue value was found higher in the fruits covered with ziplock bag and paper bag. The amount of malic acid is high in control fruits covered with a paper bag, while it was found to be lower in fruits covered with a ziplock bag. It was determined that fructose, glucose and sucrose contents of fruits were higher than those of control fruits in both fruit bagging treatments. In this study, the antioxidant content of the fruits was significantly higher than that of the control fruits growing in the ziplock bag and paper bag. Pesticide residue analyzes indicate that there are no drug residues on the fruits bagging treatment performed, while, there was a residual chemical level of 0.1 ppb in control treatment, even though it is below the reference value. As a result of this study, the practicability of "fruit bagging treatment" which can appeal to consumers who want to buy "apples that no drug touched" is discussed and recommendations made.
