Abstract:
<p>The objective of the present research was to study the post-harvest changes in quality attributes of fully ripened strawberry fruit during cold storage. The research trial was conducted using three different temperatures i.e. (0&ordm;C, 5&ordm;C and 10&ordm;C) with 90-95% relative humidity. Quality attributes studied include firmness; weight loss, total soluble solids, pH and acidity during 2 weeks of storage after three days interval. The results indicated that titratable acidity and pH were affected non-significantly as a function of storage conditions. Whereas, weight loss was rapid in the samples stored at room temperature and 10&deg;C than those stored at 0&deg;C. It was further observed that at 0&deg; C strawberry fruit showed maximum shelf life. Additionally, quality attributes remained stable as compared to 5&deg;C and 10&deg;C. The results indicated that fully ripened strawberry fruits should be stored at 0&deg;C to retain best quality under climatic conditions prevailing in Pakistan.</p>
