Effects of simulated transport vibration on storage quality and cell wall metabolism of Actinidia arguta

Actinidia arguta is rich in nutritional value and has a sweet and sour flavor. However, the postharvest transportation preservation of A. arguta still needs further improvement. Vibration damage to fresh fruit caused by post-harvest transport can significantly affect storage quality and result in quality loss. This study investigated the effects of vibration during transportation on storage quality (sensory, physicochemical, nutritional quality) and cell wall metabolism of A. arguta. The results indicated that simulated transport vibration facilitated the wrinkling of the fruit and the decline in firmness during storage, leading to a reduction in sensory scores at the end of storage. It also intensified decay and weight loss, while accelerating the degradation of vitamin C (Vc) due to vibration stress and mechanical damage. Additionally, the breakdown of original pectin and the generation of soluble pectin were promoted, accompanied by increased activity of PG, PME, and PL enzymes during storage. In conclusion, simulated transport vibration significantly expedited the quality deterioration of A. arguta during storage, resulting in a marked reduction in fruit quality. Therefore, minimizing transportation vibrations plays a crucial role in maintaining product quality during storage and transit in the supply chain logistics of A. arguta. This study provides a theoretical basis for the subsequent solution of the problems of the A. arguta after transport and promotes the sustainable development of A. arguta industry.
