Application of edible coatings to improve global quality of fortified pumpkin
A refrigerated ready-to-eat food fortified with iron (Fe) and ascorbic acid (AA) was produced using pumpkin (Cucurbita moschata Duchesne ex Poiret) and applying a dry infusion process. It was observed that the presence of both Fe and AA in the vegetable matrix (control system) produced the browning...

A refrigerated ready-to-eat food fortified with iron (Fe) and ascorbic acid (AA) was produced using pumpkin (Cucurbita moschata Duchesne ex Poiret) and applying a dry infusion process. It was observed that the presence of both Fe and AA in the vegetable matrix (control system) produced the browning of the product. The edible coatings application based on k-carrageenan or tapioca starch was proposed in order to improve the product stability. The AA degradation in the tissue was significantly reduced in the pumpkin with a starch-based coating. The result of an "in vitro" gastric and intestinal digestion assay indicated that when Fe was in the coating, Fe solubility at pH 2 was lower than control and tended to improve at pH 8. It was interpreted as a better accessibility of Fe at intestinal lumen level, and moreover, it could avoid gastric side effects. The products obtained were safe from microbiological view point and presented a satisfactory color and texture. Industrial relevance The formulation of food fortified with iron (Fe) represents a challenge from nutritional as well as technological view point because the reactivity of this mineral with other food matrix nutrients.
