“…The PI assessment is defined as an important quantification of peroxides and other products resulting from the oxidation of the oil at the end of the reaction. [ 32 ] According to ANVISA, [ 31 ] the accepted value for this parameter is a maximum of 15 meq kg −1 , indicating that both products are following the legislation for commercialization.…”

Background: In the search for healthier and more functional foods, dietary triglycerides (TAGs) have played a prominent role in the food industry. The objective of this work was to evaluate new clay supports to immobilize lipase from Rhizopus oryzae and use it in the synthesis of TAGs. Main methods and major results:The immobilization of lipase by physical adsorption was carried out, determining the hydrolytic activity, esterification, immobilization yield, thermal stability, and kinetic and thermodynamic parameters. Afterwards, acidolysis was carried out and the product characterized as to composition, acidity index (AI), peroxide index (PI), and analysis of the sn-2 position. The mean hydrolytic activity of free lipase was 23,568.43 ± 559.20 U g −1 and for lipase immobilized in acidified kaolin and diatomite, 1409.04 ± 51.07 and 1235.67 ± 9.56 U g -1 ; immobilization yield of 23.78% and 20.21% and esterification activity of 1827.99 and 1722.66 U g -1 , respectively, maintaining more than 60% of the relative activity after 8 h of incubation at different temperatures. The reaction using the derivative immobilized in acidified diatomite resulted in the degree of incorporation (DI) 41.53% ± 3.99%. Conclusions and implications:From the results, the potential of diatomite and kaolin as support in the immobilization of lipase for the synthesis of dietary TAGs was verified.

“…This difference was attributed to the drying conditions since carotenoids are known for being thermosensitive. In the study carried out by Mesquita et al [53] with commercial buriti oil samples, the total carotenoids content ranged from 83.691 to 103.696 µg 100 g −1 . When the commercial buriti oil samples were submitted to enzymatic interesterification, the CT content doubled to around 2786.83 ± 113.09 µg g −1 [53].…”

Epidemiological studies have shown that a diet rich in bioactive components significantly reduces cardiovascular disease incidence and mortality. In this sense, there is a need for meta-analytical research that confirms this phenomenon and increases specific knowledge about certain bioactive compounds such as carotenoids. Thus, this systematic review and meta-analysis aim to disseminate knowledge about the sources of carotenoids in fruit consumed in the north of Brazil which are outside the Brazilian trade balance. A systematic review and a meta-analysis following the PRISMA guidelines were conducted based on a random effects synthesis of multivariable-adjusted relative risks (RRs). Searches of seven sources were carried out, including PubMed, Science Direct from Elsevier, Web of Science, Scielo, Eric Research and Google Scholar databases. The systematic review was guided by a systematic review protocol based on the POT strategy (population, outcome and type of study) adapted for use in this research. Mendeley was a resource used to organize and manage references and exclude duplicates of studies selected for review. In this review, we present the potential bioactive compounds concentrated in little-known fruit species from the Amazon and their benefits. Consuming fruits that are rich in notable constituents such as carotenoids is important for the prevention of chronic non-communicable diseases through anti-inflammatory and anticoagulant properties, as well as antivirals, immunomodulators and antioxidants agents that directly affect the immune response.

“…O índice de peróxido representa a oxidação do óleo, visto que, são os primeiros compostos liberados na deterioração de ácidos graxos, retratando os radicais livres. Em óleos prensados a frio, a Comissão Codex Alimentarium estabelece que o valor de peróxidos deva ser de no máximo 15 meq/kg (MOURA et al, 2019;MESQUITA et al, 2020). Portanto com 0,77 meq/kg, o óleo de castanha-de-cutia segue no padrão (Tabela 3).…”

The Brazilian Amazon rainforest is rich in natural resources, which are widely used in areas such as food and health, especially for local populations. Couepia edulis Prance is a tree from the Amazon, consisting of fruits called agouti nut, which its use as a herbal medicine is widespread in the Amazon region. That said, the aim of this article was to verify the cytotoxicity of Agouti nut oil. For this, the nutritional characteristics, physical-chemical and bioactive properties of agouti nut oil were verified, for subsequent cytotoxicity bioassay. In the centesimal composition it was identified: Caloric Value 658.84± 0.02; Proteins 10.01 ± 0.03; Ash 2.34 ± 0.04; Lipids 61.20 ± 0.15; Carbohydrates 17.00 ± 0.20; Fibers 29.74 ± 0.64. In the fatty acid profile: arachidic (0.42%), palmitoleic (1.02%), stearic (7.11%), linoleic (14%), palmitic (29.20%), oleic (35.01%). In the cytotoxicity assay at different extract concentrations (100; 50; 6.25 and 1.56 µg.mL-1) cell viability of 78.60 to 90.20% was identified. We conclude that the almond and the oil of the Agouti nut at the nutritional and physical-chemical level were within the food standards for consumption, with a high content of total fibers.
