Fresh vegetables have high water content and low acidity, so drying can extend shelf life, allowing the obtaining of alternative flours for the development of new products. The study aimed to investigate the influence of the melon harvest and off-season on the chemical composition of melon (Cantaloupe, Charentais e Honey Dew) flours and the potential application in products. The flours were evaluated for granulometry, morphology, centesimal composition, lipid and mineral content, total phenolic compound (TPC), antioxidant activity, and technological properties.

Yellow mombin (Spondias mombin) and Brazil plum (Spondias tuberosa) seeds are byproducts of exploiting their pulp and currently have no relevant food or industrial applications. Thus, the present study aimed to evaluate the physicochemical, technological, and functional characteristics of flours obtained from yellow mombin (YMF) and Brazil plum (BPF) residues. The flours presented a high percentage of insoluble fiber (68.

Background: Parasitic contamination in vegetables is a reality in several countries and a challenge for food safety. The risk of consumption usually raw, associated with failures in good practices of production, transportation, and preparation further increase the possibility of ingesting contaminated food. Given this, a systematic review was carried out to scientifically demonstrate the effectiveness of sanitization protocols in the parasitic decontamination of plants.

Background: Intestinal mucositis is one of the most common and important side effects of 5-fluorouracil (5-FU). Currently, there are still no specific and effective protocols for its prevention and treatment. The aim of the present study was to evaluate the effect of oral administration of Lacticaseibacillus casei () on the progression of 5-FU-induced intestinal mucositis.

Toxoplasmosis, despite advances in science and technology, is a disease that requires attention since there is no vaccine capable of immunizing humans and animals against all isolated types of Toxoplasma gondii. Thus, the use of chimeric proteins, which can contain multiple antigens, is a very promising alternative for the process of obtaining a vaccine and diagnostic test for toxoplasmosis due to the great diversity of antigens presented by T. gondii.

Background: Food processing produces large volumes of waste that can be transformed into useful and relevant ingredients. The by-product of oil extraction from faveleira seeds is a potentially low-cost raw material that can be used for obtaining functional foods. This study aimed to analyze the physicochemical properties, chemical composition, and antioxidant activity of faveleira (Cnidoscolus quercifolius Pohl) seed press cake flour (FSPCF).

Background: Parasitic contamination of vegetables is a public health problem in several countries and a challenge for food safety. With a short path from the field to the table, these foods can suffer several flaws in the good practices of production, transport and packaging which culminate in an offer of contaminated food to consumers. Therefore, this study describes a systematic review protocol with meta-analysis on evaluating the effectiveness of existing sanitation methods in removing parasites from vegetables.

The present study evaluated the cytotoxicity, antioxidant potential, and antimicrobial effect on the antibiotic activity modulation of gelatin nanoparticles containing buriti oil (OPG). The cytotoxicity analysis was performed on Chinese Hamster Ovary Cells (CHO) using a MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] test. The antioxidant potential of buriti oil and OPG was determined by total antioxidant capacity, reducing power, and the ABTS (2,2'-azinobis-3-ethylbenzothiazoline-6-sulfonic acid) test.

The quinoa oil presents benefits to health, but its low water dispersibility in the aqueous matrix and instability of bioactive compounds is challenging for food application. This study performed the physicochemical and chemical characterization of quinoa oil and evaluated its water dispersibility and 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging activity after nanoencapsulation in porcine gelatin and combination with whey protein isolate by emulsification O/W technique. Thus, three formulations were obtained: 1) OG-containing quinoa oil and porcine gelatin in aqueous phase 2; 2) OWG1-containing quinoa oil, whey protein isolate, and porcine gelatin in aqueous phase 2; and 3) OWG2-containing quinoa oil and whey protein isolate in aqueous phase 1, and porcine gelatin in aqueous phase 2.

Leishmaniosis is caused by the protozoa of the genus Leishmania with a wide spectrum of clinical and epidemiological manifestations which are characterized into four clinical groups: cutaneous, mucocutaneous, diffuse cutaneous, and visceral. American visceral leishmaniosis (AVL) or visceral leishmaniosis (VL) has been known as the most severe form of the disease. However, despite the growing number of people exposed to the infection risk and the great effort done by the scientific community worldwide to significantly increase the knowledge about these diseases, there is no vaccine capable of preventing VL in humans.
