OLIVEIRA, Hernete de Jesus Santos et al. Carbohydrate measuvements on four brands of coconut water. Ciênc. agrotec. [online]. 2003, vol.27, n.5, pp.1063-1067. ISSN 1413-7054.  https://doi.org/10.1590/S1413-70542003000500013.

Utilization of water from dry coconuts to produce long-life coconut water, using a 20% mixture of green coconut water in order to reach the quality standard demanded by Brazilian customers, has been done since 2000. That is one more alternative for the by products from Cocos nucifera L. processing industries, introducing marketing advantages like: better storage, longer shelf life, transportation, and visual quality to the customer. Packed with ultrasonic Swedish technology, coconut water has been already commercialized in establishments in Southeastern Brazil. In this work, carbohydrate contents of four coconut water brands and the natural coconut water were comparatively analyzed, and the contents of fructose, glucose, sucrose, total sugars, and reducing sugars were determined. The coconut water used in this research was bought in Lavras, Minas Gerais St., as well as the green coconut water, which was used as a control. The statistical design was completely randomized, and the treatments were five brands with five replicates. The analyses were performed in the Biochemistry laboratory, of UFLA's Chemistry Department. Two out of four commercial brands, brands B and D, did not achieve the quality standards cited in the literature.

Palavras-chave : Cocos nucifera L.; carbohydrates; fructose; sucrose; glucose.
