  Compositions and consumables comprising certain sweeteners and at least one dihydrochalcone of Formula I are provided herein, wherein the at least one sweetener is selected from certain steviol glycoside and/or mogroside sweeteners in sweetening amounts. The at least one dihydrochalcone enhances the sweetness of the consumable and optionally modulates one or more taste attributes to make the consumable taste more like a sucrose-sweetened consumable. Methods of enhancing the sweetness of a consumable, methods of making a consumable taste more like a sucrose-sweetened consumable and methods of preparing consumables are also detailed herein.

  本文提供了包含某些甜味剂和至少一种式I的二氢黄酮的组合物和消耗品，其中至少一种甜味剂选自某些甜菊苷和/或蒙果甙甜味剂，用于调味。至少一种二氢黄酮增强了消耗品的甜味，并可选择性地调节一个或多个口味属性，使消耗品的口感更像蔗糖甜味的消耗品。本文还详细介绍了增强消耗品甜味的方法，使消耗品口感更像蔗糖甜味的方法以及制备消耗品的方法。

  The invention relates to a process for the biosynthetic production and recovery of [5S,6S]-6-amino-5-hydroxycyclohexa-1,3-diene-1-carboxylic acid) catalyzed, at increased enzyme activity, at least by an enzyme belonging to the class of aminodeoxyisochorismate (ADIC) synthases and an enzyme belonging to the class of isochorismatases, wherein (a) the production is carried out fermentatively with a suitable carbon source as starting material in a chorismate overproducing host microorganism, and with an aminodeoxyisochorismate (ADIC) synthase enzyme selected from the group of such ADIC synthase enzymes that are lacking ADIC lyase activity, and (b) the recovery is carried out by means of concentrating the supernatant of the fermentation to a 2,3-CHA concentration of at least 25 g/l, followed by crystallisation from the said concentrated supernatant. In a second embodiment, the present invention relates to the use of [5S,6S]-6-amino-5-hydroxycyclohexa-1,3-diene-1-carboxylic acid (2,3-CHA) as a catalytically active product, in particular as a chiral catalyst. Finally, the invention relates to the novel zinc complex of 2,3-CHA.
