Minerals in Aqueous Extract of the Coproducts Myrciaria dubia (Kunth.) McVaugh, Myrtaceae

Abstract

The camu-camu of fruits (Myrciaria dubia (HBK) McVaugh, Myrtaceae) arising from Amazonia, are considered a major source of vitamin C in the world. There are still important sources of different bioactive compounds and good source of minerals such as sodium, potassium, calcium, zinc, magnesium, manganese and copper. However, the processing of these fruits for extraction of the pulp, the product of greatest interest to many consumption, creates an effective quantity of different wastes, solid and liquid, capable of utilization for various uses its technological potential is studied. Thus, this work aimed at determining, quickly, via direct condutometric electroanalytical method, the amount of dissolved minerals contained in the aqueous extract of processed seeds and peels, coproducts of Myrciaria dubia, with potential use in the area of biotechnology development. The samples used for the study come from the experimental processing of fruit camu-camu. Three coproducts (byproducts/waste) named: CF, CS and SSC also processed via Standard Operating Procedure (SOP) created in our own laboratory for the study of organic waste. Analyzing the results obtained it was found that the samples CF and SSC showed higher electrical conductivity, which characterizes them as a rich source of electrolytes, showing greater ability to exchange ions to the solution, which can be characterized as a nutrient solution. Conductivity values obtained from samples from CF, CS and SSC outweigh some brands of bottled water sold in the Brazilian market, ranging from 32 to 72% when compared to the highest value obtained, 408,0 S.cm-1 at 25°C, considered as a nutrient solution of high value rich in minerals. The conductometry technique was effective for rapid determination of total dissolved coproducts of processed fruit samples camu-camu minerals. It also made possible by the high mineral contents, characterize them as nutrient solution, with potential for exploitation in the area of biotechnology development.

Formulação e caracterização agroindustrial de farinha de mandioca d’água enriquecida com protótipos de farinha de camu-camu

“…Os protótipos enriquecidos com farinhas de camu-camu elaborada a partir de resíduos beneficiados e frutos inteiros, continham valores de ácido ascórbico muito superior aos registrados na literatura científca, a exemplo dos estudos de Em síntese, pode-se afirmar que, a qualidade de farinhas de resíduos agroindustriais é uma demanda de relevância crescente em diversas indústrias (SHIRAHIGUE; CECCATO-ANTONINI, 2020), a exemplo as do ramo de alimentos, cosmético e biotecnologia. Demanda esta que, vêm sendo motivadora para condução de investigações e trabalhos regionais que, buscam evidenciar o potencial de aproveitamento integral através do beneficiamento dos resíduos de processamento de espécies nativas, a exemplo de produtos de camu-camu (SOUSA et al, 2015;SOUSA, 2016;GRIGIO et al, 2021).…”

Phytotoxicity of extracts of Myrciaria dubia (Kunth) McVaugh bioprocessed in vegetable crop sensitive to allelochemicals

“…From the established treatments (T1 and T2), the biological assay was performed in specialized laboratory using sterilized materials, deionized water, ionic contaminants free and BR aqueous extracts, five repetitions for each witness control (WC) and treatments, obtained by means of two dilutions (D1 and D2) respectively defined by the ratio m: v, 1:10 normally used in the assessment of organic compounds and 1: 100 was performed as Sousa et al (2015).…”

Essential oils from condiment and medicinal plants in the control of contaminants from the micropropa-gation of Myrciaria dubia

“…Camu-camu (Myrciaria dubia (HBK) McVaugh) is a wild fruit that grows on the floodplains of rivers and lakes throughout the Amazon basin, its pink to dark purple fruit being of great commercial interest thanks to their nutritional, agro-industrial and pharmacological potential, which includes properties such as high concentrations of ascorbic acid; mineral compounds such as potassium, calcium, magnesium and sodium; and phenolic compounds (CHAGAS et al, 2015;SOUSA et al, 2015, GRIGIO et al, 2019GRIGIO et al, 2021aGRIGIO et al, , 2021bGRIGIO et al, , 2021c. Due to the species having excellent levels of antioxidant activity, it is capable of minimizing the risk of incidence of a number of chronic diseases, which allows it to be in-cluded in the list of functional foods (PETERS; VÁSQUEZ, 1986;VILLACHICA, 1996;YUYAMA et al, 2011;SOUSA et al, 2015;. Although the species is traditionally propagated by seeds, this technique is not interesting for the establishment of commercial agriculture due to the lack of uniformity generated by sexual reproduction, which impacts on the variability regarding fruiting, production cycle, and even alterations in the vitamin C content among the fruits of different plants (PASQUAL et al, 2012;CHAGAS et al, 2012).…”
