However, the postharvest transportation preservation of <em>A. arguta</em> 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 <em>A. arguta</em>. 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 <em>A. arguta</em> 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 <em>A. arguta</em>.

In spite of effectiveness of the conventional fumigants, huge concerns raised for adverse effect on environmental and human health, thereby prompting interest in exploitation of plant-derived volatile oils (VOs) as eco-friendly alternatives. The present study aimed to evaluate fumigant toxicity of nine VOs of &lt;em&gt;Myrtus communis&lt;/em&gt; (McEO), &lt;em&gt;Citrus sinensis&lt;/em&gt; (CsEo), &lt;em&gt;Melaleuca alternifolia&lt;/em&gt; (MaEO), &lt;em&gt;Eucalyptus globulus&lt;/em&gt; (EgEO), &lt;em&gt;Alllium sativum&lt;/em&gt; (GEO), and &lt;em&gt;Brassica juncea&lt;/em&gt; (MEO) (four varieties individually) against &lt;em&gt;T. castaneum&lt;/em&gt; and &lt;em&gt;C. cephalonica&lt;/em&gt;. The fumigant toxicity of VOs varied in the order of GEO &gt; MEO &gt; CsEO &gt; McEO &gt; EgEO &gt; MaEO.

However, past estimations of how much grain the SGR is supposed to hold employed static models that did not consider the dynamic nature of food requirements presented by climate change and volatile food prices, let alone the duo objectives of achieving food security whilst minimizing storage costs.
