Probably the same people who choose filtered orange juice over the pulpy variety. Too bad, because both the albedo and the pulp are good sources of pectin, a type of fiber that shows great nutritional promise.</p> Wed, 04 Jan 2023 11:00:00 +0000 Joe Schwarcz PhD 9348 at /oss /oss/article/nutrition-you-asked/can-one-rotten-apple-really-spoil-whole-barrel <p>Is there any truth to the expression, "one rotten apple spoils the whole barrel"? You bet. Because once an apple is rotten or has physical damage, (ie a bruise), it produces ethylene, which in turn leads to a slightly increased internal temperature causing a breakdown of chlorophyll and the synthesis of other pigments. The starch in the fruit is converted to simple sugars and at the same time, pectin, a component of fiber that cements the cell walls together, begins to disintegrate thereby softening the tissue.</p> Tue, 03 Dec 2019 20:49:43 +0000 Joe Schwarcz PhD 8026 at /oss
