Red araçá pulp microencapsulation by hydrolyzed pinhão starch, and tara and arabic gums

Abstract

BACKGROUND Red araçá is a Brazilian native species whose fruits are rich in phenolic acids, flavonoids, anthocyanins, and carotenoids. To preserve the properties of compounds during processing, red araçá pulp (RAP) was encapsulated by hydrolyzed pinhão starch (PS), tara gum (TG), and arabic gum (AG) in different blends in equal proportions, serving as a coating material. RESULTS Fresh RAP had a gallic acid equivalent of 3098 mg per 100 g of dry weight, 156.29 μg β‐carotene per gram of dry weight, total anthocyanins of 18 mg per 100 g of dry weight and exhibited high antioxidant activity. The highest encapsulation efficiency achieved with the PS, TG, and AG blend was 80.4% for the total carotenoids, and that for the total anthocyanins was 76% with the TG and AG blend. Only one step of antioxidant activity degradation was identified, and the carrier system PSTG was efficient at maintaining the antioxidant activity, with half‐life of 23.60–37.27 days. CONCLUSION The use of PS alone as a coating material or associated with TG and AG gums resulted in improved retention of bioactive compounds, these being an excellent alternative coating material since they improved the stability of the antioxidant activity of RAP. © 2020 Society of Chemical Industry

Propriedades Nutritivas e Bioativas do Araçá (Psidium cattleianum Sabine)

“…Floresce entre os meses de outubro e novembro e a segunda em dezembro. Podendo casualmente florescer em março, sendo assim, os frutos podem ser colhidos de outubro a março (Brasil, 2015;Possa, 2016;Rosário et al, 2020;Meregalli et al, 2020;Pereira et al, 2018). Na região sudeste do Paraná, Brasil, Kosera Neto et al (2020), relataram que o crescimento do araçá-vermelho ocorre entre julho e novembro, com floração entre outubro e novembro, e amadurecimento dos frutos no final de dezembro a março.…”

“…O araçá possui alto potencial agroalimentar pela abundância em compostos bioativos, elevados teores de substâncias fenólicas que são positivamente correlacionados com a atividade antioxidante, anti-inflamatória, antimicrobiana, os quais são benéficos a saúde na prevenção de doenças (Possa, 2016;Pereira et al, 2018;Rosário et al, 2020;Meregalli et al, 2020).…”

“…Os compostos bioativos que se destacam com ação antioxidante são os compostos fenólicos (antocianinas, flavonoides e ácidos orgânicos) e os carotenoides (licopeno, β-caroteno, zeaxantina, entre outros) (Rosário et al, 2020). Em comparação com morangos e uvas, o araçá possui teores de compostos fenólicos totais superiores, e na mesma faixa da pitanga e da ameixa.…”

Biological activity and chemical composition of native fruits: a review

“…The results showed that the important bioactive compounds (phenolic compounds, anthocyanins and ascorbic acid) were not lost and these new products may be a good option for the use of cattley guava pulp (26) . The red cattley guava pulp was also encapsulated with excellent results in the retention of bioactive compounds and maintaining antioxidant activity (27) .…”

An Integrative Review on the Main Flavonoids Found in Some Species of the Myrtaceae Family: Phytochemical Characterization, Health Benefits and Development of Products

“…Araçá has high agro-food potential due to its chemical composition. Among the compounds found in this fruit, organic acids, carotenoids, and flavonoids stand out [ 19 ]. In terms of the proximate composition of the fresh fruit, the nutrient contents are found in the following concentrations: 81.73–84.9 g of moisture; 4.32–10.01 g of carbohydrates; 3.87–6.14 g of fiber; 0.63–1.50 g of minerals; 0.75–1.03 g of proteins, and 26.8 kcal of energy [ 18 ].…”
