“…In this work, identification of betalains was achieved using LC‐PDA‐ESI‐MS 2 and the data reported by other authors for the Opuntia spp. (Castellanos‐Santiago & Yahia, ; Chauhan, Sheth, Rathod, Suhagia, & Maradia, ; Stintzing et al, ; Strack et al, ; Yahia, Castellanos, & Mondragon‐Jacobo, ). This approach led to the identification of three betaxanthins, three betacyanins and one decarboxylated betacyanin in our samples (Table ).…”

Opuntia ficus‐indica fruits have an important nutritional value and show several biological properties. This work studied the fruit physicochemical characteristics of two wild ecotypes (“Green” and “Orange”) and two cultivars (“Rossa” and “Gialla”) from Portugal. The results showed that the largest and heaviest fruits were those from ecotype “Orange,”, whereas the wild ecotype “Green” had fruits with firmer flesh. The fruit peels of cultivars “Rossa” and “Gialla” presented the highest fibre content. Glucose was the major carbohydrate in the fruits, particularly in the peels. Malic acid was the sole organic acid in both peels and pulps of all samples. The betacyanins’ content was higher in fruits of the “Rossa” cultivar, and the higher betaxanthins’ content was present in the peel of the cultivar “Gialla.” Peels of all samples generally had higher amounts of betalains than the pulps. The peel was a better scavenger of DPPH and ABTS free radicals than the pulp. Practical application The wastes of diverse food industries have revealed the presence of bioactive compounds with added value. The fruits of Opuntia ficus‐indica are appreciated for possessing biological attributes, nevertheless the peel generally is not used. The present work shows that the pigments (betalains) are predominantly found in the peel. Moreover, the in vitro antioxidant activity was also higher in this part of the fruit, independent on the ecotype or cultivar studied. Such results might trigger the interest for these residues from which pigments and bioactive compounds can be extracted, and, as extracts, can be used in diverse domains particularly in food and pharmaceutical industries.

“…Sin embargo, la extracción acuosa, fue el método con mayor diferencia significativa (p<0.05), obteniendo valores de 1009.01±8.86 y 764.18±2.11 mg EB/100 g bs, respectivamente. Este comportamiento fue similar a lo reportado por Yahia y Castellanos-Santiago (2008), dónde realizaron extracciones con diferentes muestras de tuna la extracción más eficaz fue la acuosa, presentando los valores más altos de betalaínas, atribuyéndose a que las betalaínas son cromoalcaloides nitrogenados solubles en agua (Chauhan, et al, 2013).…”

El residuo de betabel ha llamado la atención entre la comunidad científica por su composición nutrimental, principalmente por sus antioxidantes, los cuales son importantes en la dieta de las personas ya que estos disminuyen el daño celular generado por los radicales libres que se generan normalmente en el metabolismo y durante el estrés oxidativo de enfermedades no transmisibles; sin embargo este residuo no es consumido ni comercializado. Por estas razones se desarrollan algunos métodos para la extracción de compuestos sin el uso de solventes como lo es el ultrasonido (US), siendo una alternativa para la extracción de compuestos conservando sus características naturales. El objetivo de este estudio fue extraer los antioxidantes del residuo de betabel (Beta Vulgaris) utilizando tecnología convencional y emergente. Se obtuvo un extracto acuoso, etanólico, macerado y por US. Los resultados mostraron que en compuestos fenólicos totales (CFT), la extracción por US obtuvo mayor cantidad de estos compuestos (534.64 EAG/100g bs) con respecto al control. Sin embargo, la mayor extracción de betaninas y betaxantinas fue con agua (1009.01 y 764.18 mg EB/100g bs). El ultrasonido es una tecnología emergente que podría ser utilizado para la extracción de compuestos antioxidantes provenientes de residuos del procesamiento de los alimentos reduciendo el consumo de energía, mejorando la vida útil y la calidad del producto.

“…Although high-performance liquid chromatography is an excellent means in the analysis of betacyanins, presently, the estimation of betacyanins carried out by spectrophotometer is more rapid, reliable, and economic (Chauhan et al 2012). In this study, the total contents of betacyanins have been determined by using a spectrophotometric method according to the formula reported by Stintzing et al (2005).…”
