berry pomace; dietary fiber; techno-functional properties; hypoglycemic; hypolipidemic properties
This study evaluated and compared the functional properties of dried pomace powders from cranberries, lingonberries, sea buckthorns, and black currants. The powders were rich in dietary fiber and exhibited good water-holding and swelling capacities. They also showed hypoglycemic and hypolipidemic properties in vitro. The study suggests that these berry pomace powders have potential applications in food products.
This study aimed to evaluate and compare the dried pomace powder of cranberries, lingonberries, sea buckthorns, and black currants as potential food ingredients with functional properties. The composition and several physicochemical and adsorption properties associated with their functionality were investigated. Tested berry pomace powders were rich in dietary soluble fiber (4.92-12.74 g/100 g DM) and insoluble fiber (40.95-65.36 g/100 g DM). The highest level of total phenolics was observed in the black currant pomace (11.09 GAE/g DM), whereas the sea buckthorn pomace revealed the highest protein concentration (21.09 g/100 g DM). All the berry pomace powders that were tested exhibited good water-holding capacity (2.78-4.24 g/g) and swelling capacity (4.99-9.98 mL/g), and poor oil-binding capacity (1.09-1.57 g/g). The strongest hypoglycemic properties were observed for the lingonberry and black currant pomace powders. The berry pomace powders presented effective in vitro hypolipidemic properties. The cholesterol-binding capacities ranged from 21.11 to 23.13 mg/g. The black currant and cranberry pomace powders demonstrated higher sodium-cholate-binding capacity than those of the lingonberry and sea buckthorn pomace powders. This study shows promising results that the powders of tested berry pomace could be used for further application in foods.
