Characterization of the acerola industrial residues and prospection of their potential application as antioxidant dietary fiber source

Abstract

The present work aimed to evaluate the residue generated by the processing industry of acerola juice as a natural source of nutritional compounds and dietary antioxidant fiber. The determination of the dietary fiber, extraction and determination of phenolic compounds and antioxidants associated with dietary fiber in triplicates, expressed as mean values ± standard deviation, were performed. The pulp and refiner residues showed high contents of bioactive compounds and polyphenols, both presented high content of total dietary fiber, associated to the antioxidant activity. Ot is concluded that it is a material of high functional value and with beneficial health properties, being able to add value to products that have it as raw material.

Phytochemical composition and antioxidant potential of different varieties viz. Flor Branca, Costa Rica and Junco of green unripe acerola (Malphigia emarginata D.C.) fruits

“…Higher pH relates to lower acidity, which is consistent with the values observed in these results. It is worth mentioning that the acerola pH remains stable even in different maturation stages when compared to other varieties grown in Brazil (Ribeiro et al, 2019;Carmo et al, 2018;Mariano-Nasser et al, 2017). In this study, the SS/TA ratio presented variation between the studied varieties, (Table 1) demonstrating that these varieties are recommended for technological applications such as usage as a gelling agent, which corroborates the suggestion of Assis et al (2001), who proposed that acerola fruits in the green ripening stage can be an important source of pectin for confectionery industries.…”

Acerola by-product as a renewable source of bioactive compounds: arabic gum and maltodextrin nanocapsules

“…By-products from the pulp and refiner showed high levels of vitamin C (175.76 and 525.18 mg.100g -1 , respectively), total anthocyanins contents (19.43 and 20.54 mg.100g-1, respectively), and polyphenols (545.98 mg gallic acid.100g -1 and 647.01 mg gallic acid.100g -1 , respectively), thus contributing to high antioxidant activity, being able to add value to products that have it as raw material (Carmo et al, 2018).…”

Prospecção Científica e Tecnológica de Malpighia emarginata DC. (Malpighiaceae): espécie economicamente importante do Brasil

“…Quanto ao número de publicações sobre a espécie (Figura 5), é possível verificar que, em 2018, houve maior produção científica (n=22), isso comparado aos outros anos. Em 2018, os artigos foram impulsionados pelo crescimento de pesquisas que envolviam a atividade antioxidante do grupo (BATISTA et al, 2018;KLOSTERHOFF et al, 2018;CARMO;NAZARENO;RUFINO, 2018). Os estudos demostraram grande valor antioxidante do fruto da aceroleira e o alto valor funcional presente em fibras, tudo isso aliado à atividade antioxidante demonstra um grande valor agregado na promoção de produtos com propriedades benéficas para a saúde (CARMO; NAZARENO; RUFINO, 2018).…”
