Characterization of galactomannans extracted from seeds of Gleditsia triacantho...

The rheological behaviour, under steady and dynamic shear and extensional conditions, of two nonconventional galactomannans isolated from Gleditsia triacanthos and Sophora japonica is determined and compared to those of locust bean gum and guar gum. The studied galactomannans exhibit shear-thinning behaviour in the range of concentrations and shear rates evaluated. For similar concentrations and shear rates, th...

Extraction, purification and characterization of galactomannans from non-tradit...

This work presents a methodology for the extraction of galactomannans from seeds of four different species of Leguminosae (Adenanthera pavonina, Caesalpinia pulcherrima, Gleditsia triacanthos and Sophora japonica) to be used e.g. in the food and biomedical industries. The galactomannans were obtained by aqueous extraction followed by a precipitation with ethanol. This methodology is simpler and easier to perfor...

Optimization of edible coating composition to retard strawberry fruit senescence

The ability of polysaccharide-based (starch, carrageenan and chitosan) coatings to extend the shelf-life of strawberry fruit (Fragaria ananassa) were studied, mainly for industrial applications. The coatings and strawberries were characterized in terms of their physical properties (superficial properties, wettability, oxygen permeability) in order to optimize coating composition. The optimized coatings were the...

Retarding strawberry fruit senesce with edible coatings : industrial application

Retarding strawberry fruit senesce with edible coatings : case study

The objectives of this work were to study the ability of starch, carrageenan and chitosan based coatings to extend the shelf life of strawberry fruit (Fragaria ananassa). To do so, the surface properties of fresh strawberry and the wettability of the coatings were studied. The superficial tension of the strawberry was 28.94 mN/m, and its polar and dispersive component was 22.99 mN/m and 5.95 mN/m, respectively....
