AI Article Synopsis
- Eleven tropical fruits from Brazil were evaluated for their nutritional value, antioxidant potential, carotenoid content, and how well these nutrients are absorbed by the body.
- The study found that these fruits generally provide dietary fiber and minerals but are low in protein, with a range of carotenoid levels detected.
- Xanthophylls showed higher bioaccessibility compared to carotenes, indicating they are more easily absorbed by the body, which underscores the health benefits and encourages the consumption of these lesser-known fruits.
Article Abstract
Eleven non-conventional tropical fruits were evaluated regarding their nutritional value, antioxidant potential, carotenoid contents and bioaccessibility. The fruits were chosen due to their spread through the Brazilian territory: araçá-boi, jaracatiá, cambuití, seriguela, capeba, pitangatuba, pitanga, buriti, acerola, dovialis and abricó-da-praia. Results have shown that these fruits are in general, i.e. depending on the fruit, rich sources of dietary fibers and minerals, high in moisture, and low in proteins. Twelve carotenoids were analyzed by HPLC-DAD and results ranged from 0.04 to 104 μg/g wet weight. Xanthophylls stood out, being higher than carotenes for araçá-boi, seriguela, pitangatuba and dovialis. Bioaccessibility varied both between fruits and carotenoids ranging from 2 to 75%. Although the fruit matrix effect, xanthophylls were more bioaccessible than carotenes, while lycopene and γ-carotene presented the poorest bioaccessibility. The present study is fundamental to expand the knowledge about the fruit properties, carotenoids bioaccessibility and potential benefits for health, as well to preserve natural resources and encourage the intake of new fruits for human nutrition.

Unlabelled: Bioprospecting can uncover new yeast strains and species with interesting ecological characteristics and valuable biotechnological traits, such as the capacity to convert different carbon sources from industrial side and waste streams into bioproducts. In this study, we conducted untargeted yeast bioprospecting in tropical West Africa, collecting 1,996 isolates and determining their growth in 70 different environments. While the collection contains numerous isolates with the potential to assimilate several cost-effective and sustainable carbon and nitrogen sources, we focused on characterizing the 203 strains capable of growing on lactose, the main carbon source in the abundant side stream cheese whey from dairy industries.

Recent advances in fruit research have reignited interest in the market of tropical and unconventional fruit varieties, leading to increased investment in this sector. Additionally, consumers are currently seeking healthier food options to maintain the nutritional integrity of their diets and maximize health benefits, which has driven the demand for novel fruits and a deeper understanding of existing varieties. Despite this growing interest, knowledge of the full potential and diversity of these fruits remains insufficient for key stakeholders to reconcile sustainable production with the promotion of healthier diets within the global context.

The poultry industry in developing countries is challenged by the high cost of conventional protein and energy feed ingredients. This problem has burdened researchers to use cheap and readily non-conventional feed ingredients such as tropical leaf meals (TLMs) to reduce the cost of feed. Tropical leaf meals are high in nutrients and important bioactive compounds, such as flavonoids and polyphenols.

Our aim was to evaluate a whole-grain diet containing 0 (T1) and 60% (T2) waste papaya silage in vitro, in situ and in vivo. In vitro, biogas, methane and dry matter degradation (DMDiv), neutral detergent fiber (NDFDiv) and crude protein (CPDiv) were determined at 72 h; in situ, DM (DMDis), NDF (NDFis) and CP (CPDis) digestibility was determined at 72 h; in vivo, consumption and apparent digestibility of DM (DMI and DMD) and NDF (NDFI and NDFD), daily weight gain (DWG), rumen characteristics (pH, bacterial and protozoan counts) were determined. In addition, we performed coproparasitoscopic analysis and interviews with producers.

Article Synopsis
- Hantavirus pulmonary syndrome (HPS) is a serious disease linked to a rodent-borne virus, with a significant number of cases occurring in northwestern Argentina.
- A study in 2022-2023 tracked rodent populations using various methods to understand their connection to human HPS infections and found a clear relationship between rising rodent numbers and HPS outbreaks.
- The research suggests that monitoring climate and rodent populations can help in planning public health campaigns, while also highlighting domestic cats as potential risk factors for increased rodent-related virus transmission.
