Notes:
In the development of an intermediate moisture banana product, it was found that ripe banana halves dehydrated to a moisture content of about 30%, following blanching and/or sulfiting, are remarkably astringent. In order to understand the cause of this phenomenon, total phenolics, leucoanthocyanins and vanillin-reacting compounds were determined and found to be more extractable in astringent semidried bananas. Light microscopy observations showed that both blanching and sulfiting contribute to the leakage of tannin-like compounds from the latex cells. Overall results conform with a mechanism by which appearance of astringency in semidried banana is due to diffusion of the astringency-causing agents from the latex cells to the surrounding tissue.
