Kiwifruit (Actinidia deliciosa var. Hayward) was purchased in a local supermarket. Fruit pieces were peeled and triturated in a Thermomix (TM 21, Vorwerk, Spain), using the fourth power level for 1 min. The physicochemical characteristics of kiwifruit puree
(water content, soluble solids, water activity, and pH) were determined in order to control the fruit which was used as raw material (data not shown).
