Both of these are usually listed as a duo and are responsible for that bitter yucky taste that comes about when biting an orange after tooth brushing. Oranges contain a fair bit of citric acid, which has both a bitter and sour taste. For some reason, these compounds enhance the bitter taste and leaves the sour taste unaffected.</p> Thu, 06 Jun 2019 16:00:00 +0000 Joe Schwarcz PhD 7788 at /oss
