A shelf life extender composition will decrease the staling rate of yeast leavened baked goods by at least 10%, and generally up to 40%, when the baked goods are shelf stored at temperatures ranging from about 4°C up to 22°C. The shelf life extender composition comprises a mixture of fruit pectin and fruit fibre, in the range of 20% up to 60% by weight of fruit pectin, with the balance of the mixture being fruit fibre. The shelf life extender is incorporated into the dough formulations for yeast leavened baked goods as an initial constituent, in an amount of 1% up to 5% by weight of the flour constituent of the dough formulation. After baking and cooling, considerably improved softness of the baked goods can be noted for periods of up to 12 to 14 days. By reducing the rate of staling, which is determined by measuring the softness of the stored baked goods over time, and noting that baked goods incorporating the shelf life extender composition are softer than those which do not, over time, the shelf life of those baked goods has therefore been increased. Since the shelf life extender composition is derived from fruits, particularly citrus fruits but also apples, the shelf life of the baked goods incorporating the shelf life extender is improved without the use of chemical or non-naturally occurring additives.

Composition prolongeant d'au moins 10 % et généralement jusqu'à 40 % la durée de conservation à l'étalage de produits de boulangerie fermentés en réduisant le taux de rassissement des produits conservés à des températures pouvant varier entre 4 et 22 degrés Celsius. La composition prolongeant la durée de conservation à l'étalage comprend un mélange de pectine et de fibres de fruits, dans une proportion de 20 à 60 % en poids de pectine, le reste du mélange consistant en des fibres de fruits. La composition est intégrée à la pâte pour produits de boulangerie fermentés, en tant que composant initial, dans une proportion de 1 à 5 % en poids de la farine constituant la pâte. La souplesse grandement améliorée des produits de boulangerie cuits et refroidis est observable pendant une période allant jusqu'à 12 à 14 jours. En réduisant le taux de rassissement, déterminé en mesurant la souplesse des produits de boulangerie en présentoir sur une période donnée, on constate que les produits de boulangerie contenant la composition permettant d'en prolonger la durée de conservation à l'étalage sont plus souples que ceux qui n'en contiennent pas. Cette composition permet donc de prolonger la conservabilité en présentoir de ces produits. Puisque cette composition est dérivée de fruits, en particulier d'agrumes mais aussi de pommes, la durée de conservation à l'étalage des produits de boulangerie contenant la composition s'en trouve accrue sans additifs chimiques ni artificiels.
