“…A chromatographic profile of the anthocyanin profile of H. sabdariffa hydroethanol extract is presented in Fig The anthocyanin compounds (peaks 10-13) were identified taking into account the identifications performed by Abdel-Moemin (2016) and Sinela et al (2017), being identified as delphinidin-3-O-sambubioside (peak 10), delphinidin-3-O-glucoside (peak 11) and cyanidin-3-O-sambubioside (peak 13). The most abundant compounds present in both extracts were 5-(hydroxymethyl) furfural and delphinidin-3-Osambubioside, as also described by Abdel-Moemin (2016) and Sinela et al (2017). According to several studies, these two compounds have been previously reported to have bioactive potential.…”

A B S T R A C TThe nutritional and bioactive composition of plants have aroused much interest not only among scientists, but also in people's daily lives. Apart from the health benefits, plants are a source of pigments that can be used as natural food colorants. In this work, the nutritional composition of Hibiscus sabdariffa L. was analysed, as well as its bioactive compounds and natural pigments. Glucose (sugar), malic acid (organic acid), α-tocopherol (tocopherol) and linoleic acid (fatty acid) were the major constituents in the corresponding classes. 5-(Hydroxymethyl) furfural was the most abundant non-anthocyanin compound, while delphinidin-3-O-sambubioside was the major anthocyanin both in its hydroethanolic extract and infusion. H. sabdariffa extracts showed antioxidant and antimicrobial activities, highlighting that the hydroethanol extract presents not only lipid peroxidation inhibition capacity, but also bactericidal/fungicidal inhibition ability for all the bacteria and fungi tested. Furthermore, both extracts revealed the absence of toxicity using porcine primary liver cells. The studied plant species was thus not only interesting for nutritional purposes but also for bioactive and colouring applications in food, cosmetic and pharmaceutical industries.

“…Roselle (Hibiseus sabdariffa L.) is an herbaceous plant, cultivated largely in tropical and subtropical areas of both hemispheres (Sinela, et al, 2017). Its calyxes contain high amounts of anthocyanins up to 1.5 g/100 g on dry weight basis (Degenhardt, Knapp, & Winterhalter, 2000).…”

“…Whereas, the Delphinidin-3-sambubioside changed to phenolic aldehyde (phloroglucinaldehyde) and phenolic acids namely gallic acid, as presented in Figure 2 [23]. The anthocyanin degradation increased for longer thermal processing [18]. There were some structural changes based on FTIR analysis (Figure 3).…”

“…The b and c peak indicated the peak of C=O (aldehyde) and =C-H (aldehyde) which form the structure of phenolic aldehyde or phloroglucinaldehyde (see Table 4). The degradation product (gallic acid, protocatechuic acid, and phloroglucinaldehyde) appeared in dried roselle extract as the effect of thermal degradation of anthocyanins [18].…”

This research studied the effect of drying temperature on the kinetic of degradation anthocyanin in roselle extract drying with foam under dehumidified air at temperatures ranging 40-60 oC. During the drying process, the anthocyanin content in the roselle extract was observed every 20 minutes for 120 minutes. The data was used for estimating the kinetic parameters of anthocyanin degradation namely constant of anthocyanins degradation rate and reaction order. The kinetic parameters were estimated and fitted with experimental data at various drying condition. Result showed that the anthocyanins degradation closed to the second order reaction. Meanwhile, the constant of anthocyanins degradation rate at various drying temperatures followed Arhenius correlation. With the result, retention of anthocyanin during the drying can be well estimated for various drying time and temperature. Copyright © 2019 BCREC Group. All rights reserved
