Determination of the Sugar Content in High-Sugar Beverages

Abstract

We determined the sugar content of 75 samples, including eight black sugar beverages (BSBs) and seven Dalgona lattes (DLs) from Seoul, Korea, using high-performance liquid chromatography-evaporative light scattering detector. The mean sugar content per 100 g was 12.7 g and 12.3 g for BSB and DL, respectively. According to the World Health Organization, the mean sugar content per serving in BSB and DL were 34.8 g and 32.5 g, respectively, equivalent to 65∼ 70% of the recommended daily intake for added sugars. The highest sugar was sucrose (56.5% in BSB and 64.4% in DL). The sugar content could be adjusted in 27 out of 40 stores for BSB and 25 out of 35 stores for DL. The relative standard deviation of the content (g/100 g) per store by the manufacturer ranged between 5.7∼21.6% for BSB and 2.3∼29.5% for DL. This suggests that a uniform recipe is required for manufacturing beverages.

Green solvents in battery recycling: status and challenges

“…If CO 2 is passed into water, the SCW becomes acidic owing to the formation and dissociation of carbonic acid, thereby increasing the extraction efficiency. 107 SCFE currently focuses on pharmaceuticals, food, 108 and chemical residues. 109 The application of SCFE in battery recycling mainly focuses on recycling LIBs; few studies investigated the recycling of other types of waste batteries.…”
