Abstract In order to study the edible coating packaging and its preservation effect to cherry tomatoes, three edible coating materials including carrageenan, carboxymethyl cellulose, sodium alginate were respectively made into coating solution, and coating packaging for cherry tomatoes were performed by the dipping way, and then they were put in the photosynthetic gas preservation box for preservation experiment. The performance of coating packaging cherry tomatoes in different experimental group were tested and analyzed. The results showed that carrageenan coating packaging significantly can reduce the water loss rate of cherry tomatoes, decay rate and MDA during storage, and delay cherry tomatoes hardness, soluble solids content, vitamin C content and organic acid content decline, and also has a better sensory evaluation. Therefore, carrageenan coating material has better effects in the preservation of cherry tomatoes.

1 Introduction The coating packaging technology and modified atmosphere preservation technology are new technology in the applicant of modern preservation packaging field, they will be a better preservation effect when both methods combined in packaging of fruit and vegetable. Three edible coating materials such as carrageenan, carboxymethyl cellulose and sodium alginate were prepared respectively coating L. Zhou J. Huang (&) H. Xing Q. Gao Y. Li X.

solution [1], coated on cherry tomatoes and performed preservation packaging experiment combined with modified atmosphere preservation technology [2]. The sensory index and physiological index of cherry tomatoes were tested, and the preservation impact of edible coating packaging on cherry tomatoes was contrastively analyzed [3]. The aim is to provide useful refer to the research and application of edible coating for fruits and vegetables [4].
