El uso de la colorimetría triestímulo permitió evaluar la estabilidad del color de los extractos enriquecidos en antocianinas (AREs) de cuatro frutas tropicales Colombianas: motilón, coral, uva de árbol y mora pequeña, a diferentes valores de pH y durante un periodo de almacenamiento de un mes. Se encontró que el color de todos los extractos...

Non-centrifugal cane sugar (NCS), also called "panela", is a high carbohydrate-content food obtained by boil evaporation of the sugar cane juice. This study was undertaken to assess physicochemical properties and sensory characteristics of panela beverage at two different concentrations. Evaluation of pH, °Brix, and colour (tristimulus...

The anthocyanin composition of tamarillo (Solanum betaceum Cav., red variety) and Andes berry (Rubus glaucus Benth.) was determined by HPLC-PDA and HPLC-ESIMS. From the anthocyanin-rich extracts (AREs), pure compounds (1-7) were obtained by MLCCC (multilayer countercurrent chromatography) and further preparative HPLC, and their unequivocal...

The pigment composition of three Colombian guava varieties, Regional roja, Regional blanca, and Palmira ICA-1, in unripe, turning and full ripe maturity stages was studied. Lycopene was identified as the major carotenoid of Regional roja and Palmira ICA-1 (18.25 and 28.07mgkg-1 fruit, respectively in full ripe fruits) although a small amount of...

Camu-camu (Myrciaria dubia) is a tropical fruit known for its content of bioactive compounds. This study aimed to evaluate physicochemically, morphologically, andsensorialpowders from camu-camu obtained by spray-drying at two inlet temperatures (150 °C and 180 °C) with three encapsulating agents (maltodextrin, whey protein and a 50:50 mixture...

Gulupa (Passiflora edulis Sims. fo edulis) is a tropical fruit native to America. This study was undertaken to characterize the physicochemical properties of this fruit in three maturity stages. In all stages, the pH, °Brix, texture, and titratable acidity were determined. pH value and solid soluble content increased during ripening and...

El consumo de guayaba está muy extendido en todo el territorio colombiano, pero su cultivo se realiza en diferentes climas y variedades. Además de las variedades Regional Blanca y Regional Roja, se está introduciendo en algunas regiones una variedad mejorada llamada Palmira, con menor contenido en semillas y más resistente a plagas. La...

Non-centrifugal cane sugar (NCS) samples obtained by traditional moulding and granulation, and also via a novel spray-drying powdering process without additives, were assessed to characterise their sugar and phenolic profiles, flavonoid content, as well as colour parameters. As expected, sucrose was the predominant sugar (91.9–95.5%), followed...
