<p>Guava (<italic>Psidium guajava</italic> L.) is a Vitamin C (ascorbic acid) rich fruit. Its production is quite high in Bangladesh but post-harvest life is very short.

The mean ascorbic acid content in guava juice (29.23 mg/100ml) and jelly (17.65 mg/100gm) were significantly lower compared to the fresh guava (192.77 mg/100gm) and also the ascorbic acid loss during storage was significant. The average score of different sensory parameters for fresh guava and guava Jelly were within the standard range. From the results, it can be concluded that guava is a good source of nutrients and quality jelly could be prepared from it.</p>
