“…These minerals contribute to bone tissue growth and bone turnover, enzymatic reactions and mineral metabolism, hematological processes, and protection of DNA integrity. 25,26 Fe deposition in target organs is important for the recovery of hematological status during nutritional ferropenic anemia. Se has an antioxidant effect and the functions of alleviation of the toxicity of heavy metals and sperm production.…”

“…Bioavailability is defined as the concentration of a metallic compound or metallic ions, present in the bloodstream, in the tissues and organs, when compared to the total concentration of that species that was ingested. Many factors may affect the bioavailability as the chemical form of the metal of interest (speciation), the complexity and interaction of metallic ions with the matrix and other compounds present in the diet (Abollino et al, 2018;Bossu, Menezes, & Nogueira, 2020).…”

Tea is one of the most consumed non-alcoholic beverages, second only to water. Medicinal plants are commonly used because they are beneficial to health. Among the several plants used whit this aim, Miconia albicans (MA), widely used for joint pain, such as rheumatoid arthritis and other inflammatory processes, and Senna alexandrina (SA), indicated for constipation and even for slimming treatments stand out. However, a little number of researches concerned with the chemical composition of these plants can be found in the literature. Thus, this work aimed to determine metallic ions in MA and SA teas using an atomic absorption spectrometer. In vitro experiments with a simulation of the gastrointestinal digestion processes were also performed (to evaluate bioaccessibility) – after in house validation – using gastric and intestinal juice. Total phenolics and total flavonoids of teas and bioaccessible fractions were also quantified. 3 samples of MA and 5 of SA were analyzed. In all samples, the total and bioaccessible concentrations of Ca, Cu and Mg were quantified. The antioxidant activity of the teas showed that, for the total phenolic content, the concentration ranged from 22 ± 1 to 29 ± 3 mg g-1, the bioaccessible fraction was close to 90% for the two studied plants. For total flavonoids, the bioaccessible fractions range from 60% (MA) to 90% (SA).

“…A bioacessibilidade do Ca determinada por solubilidade foi aproximadamente 2 vezes superior à obtida por diálise e não houve diferença estatística (p>0,05) da bioacessibilidade do cálcio entre os insetos estudados. O Ca dialisável, para ambos os insetos, apresentou valores próximos ao de fórmulas infantis líquidas (13,3 ± 1,2%) (ETCHEVERRY, et al, 2012), ao do leite bovino UHT (12 ± 1%) e ao leite de ovelha in natura (10 ± 1%), mas inferior ao leite bovino in natura (20,1 ± 0,1%), e ao leite de cabra UHT (17,4 ± 0,4%) (BOSSU et. al.…”

Insect consumption by humans has been encouraged as an alternative to conventional protein sources in light of the scenario predicted by the United Nations, in which the population will reach almost 10 billion people by 2050. It is considered an interesting alternative from the environmental and nutritional points of view. Tenebrio molitor, in the larval stage, is one of the most studied insects in the literature. To expand knowledge about the potential use of insects, in this study an evaluation if the composition of T. molitor and Zophobas morio larvae was evaluated, focusing on the composition of proteins and minerals, and in vitro bioaccessibility of Fe, Ca, Mg, and Zn. T. molitor and Z. morio have the protein as the most abundant component (49.7 g / 100 g for T. molitor and 44.5 g / 100 g for Z. morio), providing the majority of the indispensable amino acids, similarly to foods such as beans and soybeans, with methionine and cysteine as the limiting amino acids. Histidine also appears as a limiting amino acid for Z. morio. The most abundant protein fractions identified by SDS-PAGE were those responsible for melanization. Phosphorus and potassium were the major minerals found, followed by calcium, which showed an amount that exceeds almost three times the calcium content found in beef, pork and chicken, and iron exceeding almost twice the content found in beef. The bioaccessibility of the minerals Ca, Fe, Mg, Zn was assessed by two methods -solubility and dialysis -, which presented different results. When evaluated by solubility, bioaccessibility showed values much higher than dialysis, 43 times higher for Fe. This discrepancy can be attributed to the differences in the methodology. According to the dialysis method results, Mg was the most bioaccessible mineral in both insects, followed by calcium. By solubility, magnesium was the most bioaccessible mineral in T. molitor, and Zn was the most bioaccessible in Z. morio. Both insects can be considered sources of Mg, Zn and Fe, with Mg and Zn having the greatest nutritional potential due to their bioaccessibility.
