“…Hulling (HJS) induced a significant effect (P0.5) on trypsin inhibitors and phytic acid [956.1 (UIT/g) and 173.9 (mg/g), respectively] compared to raw jackfruit seeds. Antinutrients impact the digestive system and affect other metabolic systems in the body (Li et al, 2023). In the present study, the hulling and extrusion process decreased the content of trypsin and phytic acid inh ibitors; these en zymatic inhibitors influence the bioaccessibility and bioavailability of nutritional and functional phytochemical components (Biswas et al, 2022).…”

Background: Jackfruit seeds have been studied in the pharmaceutical industry, one way of exploiting the potential of this ingredient could be as a protein source in the elaboration of fish food. Jackfruit seeds were subjected to different processes to obtain meals to be added to the diet of Nile tilapia (Oreochromis niloticus). The effects of this addition on growth, elimination of antinutritional factors, and repercussion on the health of tilapia was evaluated. Method: For the bioassay of the productive yield, three experimental diets were prepared, consisting of a control diet of fishmeal and four treatments: raw jackfruit seeds (RJS), hulled jackfruit seeds (HJS), extruded jackfruit seeds (EJS) and hulled and extruded jackfruit seeds (HEJS). For the growth study, 1600-L experimental units were used. Three replicates per treatment were used, initial weight of tilapias was of 1.8±0.2 g. At the end of the feeding study, a blood sample was taken from the caudal vein, using a hypodermic syringe and EDTA as anticoagulant for the hematology (hemoglobin/hematocrit). Results: Significant differences among treatments using jackfruit seeds, subjected to hulling and extrusion (CEJS) processes, were observed in weight gain (24.3±1.1 g), whereas blood parameters, the red blood cells (RBC) count and the hematocrit (Hct) were significantly higher in the jackfruit seeds subjected to only one treatment (39.8±6.49) respect to the control diet (27.4±3.18). Regarding the MCH and MCHC variables, lower values were observed with the diets using EDJS, showing a significant diminution in the RBC concentration (13.2±2.5) compared to the control diet (19.3±4.65). The processes used for the jackfruit seeds allowed formulating diets with a higher protein quality, which resulted in an increment in weight gain, without observing any effect on the health indicators and nutritional status of fish.

“…To expand these studies and investigate the effects (beneficial or toxic) of these chemical elements, it is necessary to develop analytical methodologies for the sample preparation (wet digestion, using inorganic acids, and oxidizing agents) of seaweed;, as well as bioaccessibility tests (simulating the physiological conditions of the organism during digestion, considering three areas of the digestive system: mouth, stomach, and intestine) and bioavailability (the evaluation of permeability and absorption) in the gastrointestinal tract [86]. In the literature, studies have investigated the bioaccessibility of phenolic compounds and carotenoids in algae [87][88][89][90][91][92][93][94], but few have evaluated essential and potentially toxic elements [95][96][97].…”

Seaweeds and Corals from the Brazilian Coast: Review on Biotechnological Potential and Environmental Aspects

et al. 2023

View full text Add to dashboard Cite

Brazil has a megadiversity that includes marine species that are distributed along 800 km of shoreline. This biodiversity status holds promising biotechnological potential. Marine organisms are important sources of novel chemical species, with applications in the pharmaceutical, cosmetic, chemical, and nutraceutical fields. However, ecological pressures derived from anthropogenic actions, including the bioaccumulation of potentially toxic elements and microplastics, impact promising species. This review describes the current status of the biotechnological and environmental aspects of seaweeds and corals from the Brazilian coast, including publications from the last 5 years (from January 2018 to December 2022). The search was conducted in the main public databases (PubChem, PubMed, Science Direct, and Google Scholar) and in the Espacenet database (European Patent Office—EPO) and the Brazilian National Property Institute (INPI). Bioprospecting studies were reported for seventy-one seaweed species and fifteen corals, but few targeted the isolation of compounds. The antioxidant potential was the most investigated biological activity. Despite being potential sources of macro- and microelements, there is a literature gap regarding the presence of potentially toxic elements and other emergent contaminants, such as microplastics, in seaweeds and corals from the Brazilian coast.
