Effect of pequi (Caryocar brasiliense) and juçara (Euterpe edulis) waste extract on oxidation process stability in broiler meat treated by UV-C

The aim of this study was to determine the potential for waste extracts from the pequi (Caryocar brasiliense) and juçara (Euterpe edulis) to reduce oxidatiove processes in antibiotic-free broiler meat. The use of natural antioxidants extracted from fruit-processing wastes has been neglected. Although these residues contain high amounts of these bioactive compounds, they are often discarded by industry. Meat samples were exposed previously submitted to UV-C radiation at 1.161 mW / cm2 for 10 minutes to accelerate the rancidity process. Pequi and juçara waste extracts were obtained by microwave-assisted extraction (MAE). A total of four conditions were tested using antibiotic-free broiler thighs and drumstick meat: BN–with no antioxidant (negative control), BP–with BHT (Butylated hydroxytoluene) (positive control), BE–with juçara extract, BC–with pequi extract. The color, pH, lipid and protein oxidation (days 0, 2, 4, 6, 8 and 10), antioxidant contents and activity (days 0 and 10), and proximal composition and fatty acid profile (day 0) were tested, followed by principal component analysis (PCA). Pequi waste extract presented the highest antioxidant content and activity. BE and BC treatments presented the highest total phenolic (TPC) and flavonoid (TFC) content, and BE presented the highest total monomeric anthocyanin content (TAC). TFC increased during storage in all treatments. The waste extracts of C. brasiliense presented the highest antioxidant activity against lipid oxidation in the antibiotic-free broiler meat. Moreover, both extracts presented high antioxidant activity against protein oxidation. Although the pequi peel extract had a better effect in terms of suppressing both types of oxidation, either this extract or the jussara waste extract could be used as a technological strategy to reduce the oxidative processes in antibiotic-free broiler meat for the poultry industry. Thus, waste extracts can be a potential technology to reduce the oxidative processes in antibiotic-free broiler meat.

“…Responsible for sequestering chelating metals and free radicals, antioxidants are also present in the pequi peel. The peel is rich in gallic acid, with the potential to eliminate reactive oxygen species and act in the prevention of diseases (Rocha et al, 2015), but commonly discarded. The relationship between the part of C. brasiliense used and the action studied is shown in Table 1.…”

“…It was observed that supplementation did not significantly decrease the DNA damage index, but significantly reduced the levels of US-CRP in patients, indicating a decrease in inflammation with the use of C. brasiliense. Rocha et al (2015) evaluated the antioxidant action of the hydroethanolic extract of the pequi peel, observing the extract's ability to eliminate free radicals. His research showed that the extract showed significant antioxidant activity.…”

The interest and search for natural active principles with therapeutic properties from plants are growing, given their potential for use by the cosmetic and pharmaceutical industries. Thus, the objective of this review was to carry out a systematic analysis of scientific productions that have explored some therapeutic potential of Caryocar brasiliense. The methodology of the preferred reporting items was adopted for systematic review and meta-analysis protocols (PRISMA). Articles published in the period from 2009 to 2019 in the Web of Science and Bireme were selected and evaluated. The descriptors used were C. brasiliense, extract, and therapeutic. After applying the exclusion criteria, 25 studies were selected, elucidating a miscellany of therapeutic potentials for pequi, such as antioxidant, antifungal, antibiotic, antineoplastic, neuroprotective, regulation of blood pressure as well as analysis of the toxicity of different parts of the plant. It was verified that the pulp extract was the most used for therapeutic purposes, mainly orally. Toxicological studies have shown low toxicity for all parts of the plant, in high doses. The therapeutic benefits observed consisted mainly of antioxidant, anti-inflammatory, antimicrobial, antineoplastic, antiparasitic, and blood pressure control activities.

“…C. brasiliense can be considered safe for use. It presents large quantities of antioxidants such as carotenoids and gallic acid (Rocha et al 2015;Traesel et al 2017b). The peel of the fruit is indicated for its nutritional potential and presenting both antioxidant components and many food applications.…”

Brazil presents one of the greatest biodiversities in the world. Whether native, cultivated, or naturalized, over 48,572 species are currently recognized in the Brazilian flora. Data provided by the Brazilian Ministry of the Environment reveals more than 200 thousand registered species in the Amazon, Caatinga, Cerrado, Atlantic Forest, Pantanal, and Pampa biomes. This approaches 15% of all plant species on the planet (do Brasil 2020; Flora do Brasil 2020 em construção 2020).Many of these native Brazilian species can be used as food sources, but their potential is still little known, either due to the lack of common knowledge, to restricted distribution/or use in the country, or to simple negligence. Such plants are currently known as unconventional food plants (UFP). UFP refers to plants that have one or more parts with food potential yet with unusual use; those which are not quickly recognized or acquired by the population of a given community; and plants that generally have no market value, being only sold in small scale, or are discarded, or plants which only possess one quality that is important to the market. These UFP can be described as native or exotic, cultivated or spontaneous, and can be adapted to local environments (Kinupp and de Barros 2007). Taken together, UFP become
