Abstract:
To explore the composition and nutritional quality of the Centennial Cane brown sugar, the physicochemical indexes, nutritional constituents, active components and antioxidant activities of 3 batches of Centennial Cane brown sugar and 14 batches of commercially available brown sugar were determined. The nutritional value of Centennial Cane brown sugar was evaluated by the TOPSIS method. The results showed that the Centennial Cane brown sugar contained reducing sugar (9.10%), protein (1.54 g/100 g), fat (1.30 g/100 g), 13 amino acids (0.87 g/100 g) and 12 kinds of mineral elements (19 812.84 mg/kg). The contents of essential amino acids (0.16 g/100 g), and contents of trace elements, K (18 466.70 mg/kg), Ca (629.33 mg/kg), Fe (59.57 mg/kg) and Zn (12.18 mg/kg), were higher. The contents of total flavonoids and total polyphenols were 3.69 mg/g and 5.69 mg/g, respectively. The DPPH IC50 and FRAP values of the Centennial Cane brown sugar were 15.01~16.44 mg/mL and 0.053~0.063 mmol/g, respectively. The comprehensive analysis of entropy weight TPOSIS showed that the comprehensive nutritional quality of brown sugars S1, S8 and S12 were better and can be selected as high-quality brown sugars. In this study, the nutritional value of brown sugar was comprehensively evaluated by constructing the entropy weight TOPSIS function evaluation model, to provide certain reference for brown sugar deep processing and the development of medicinal health functional products.
