Gluten-free flours that are nutritionally balanced with appropriate functional characteristics were developed by supplementation of native and modified acha flours with protein, dietary fiber and antioxidants-rich mango kernel and soy cakes flours. Acha flour was subjected to chemical and enzymatic modifications. The proximate, mineral compositions, bioactive and antinutrients properties of the composite flours were evaluated. The water content of the composite flours with native and chemically modified acha flour was between 7.62 and 9.30%, while that of enzymatic acha flour was between 10.12 and 10.79%. However, samples made with 20 and 30% incorporated mango kernel flour had around 13 and 19% increase in the protein content respectively, others including sample with enzymatically modified acha flour had lower protein content. On the other hand, all samples with enzymatically modified acha flour had between 83 and 100% increase in fibre content. The Na/K ratio of all the samples were less than one, as nutritionally required. Samples with enzymatically modified acha flour had best total flavonoid (0.03–0.77 mgGAE/g), total phenol (2.35–11.99 mgTAE/g) and DPPH radical scavenging activities (58.29–94.02%) contents. In addition, samples with enzymatically modified acha flour had the least antinutritional values. Although all the samples had values that were significantly (p ≥ 0.05) different, the samples had significant protein, dietary fiber, minerals and antioxidants contents, while the antinutritional contents were well lower than the standard.

Heavy metal contamination has been one of the primary environmental concerns for many years in most developing countries. As the industries continue to search for low-cost and efficient adsorbents to treat their effluents contaminated with these toxic metal ions, biomass-based adsorbents have gained much attention. This work exploits such ten different biomass-based adsorbents (namely, Karanja de-oiled cake, Neem de-oiled cake, Neem leaves, Moringa Leaves, Bagasse, Mango Kernel, Wheat Bran, Eucalyptus, Fly ash, and Corn cob) for adsorption of copper ions in particular. Further, selected adsorbents (namely Karanja de-oiled cake, Neem de-oiled cake, Bagasse, Wheat Bran and Mango Kernel) were taken to the next stage and modified to biochar and tested again for copper removal. Among the biomass-based adsorbents, the highest adsorption capacity was observed for Neem de-oiled cake (equal to 9.6 mg/g). While for biochar-based adsorbents, Bagasse showed the highest adsorption capacity for copper (equivalent to 13.0 mg/g).

<p>The study was aimed to look at the effect of different forms of mango kernels (MK) on the shelf life of refrigerated beef sausages over 12 days of cold storage. The (MK) was chemically and microbiologically analyzed. Beef sausages were treated with MK in 3 states, as dry ground (1.5%), an extract (1.5%) and spray MK extract (1.5%) over minced beef of sausages. Two controls were used; BHT 0.02% and no additives. A series of analyses were performed after treatments; thiobarbituric acid reactive substances (TBARS), analysis of color, myoglobin and odor. The results indicated that different forms of MK added to the beef sausages had different effects on its shelf life. Furthermore, the sprayed MK extract has significantly (P ?0.05) lowered metmyoglobin (MMb) and TBARS and increased oxymyoglobin (MbO<sub>2</sub>), odor score and a* (redness) than other forms. The potential effects of the sprayed MK may be due to a cloud of droplets cover the large surfaces of minced beef sausages with efficient extracted antioxidants. MK is source of flavonoids 142mg/g F.W. GAE. The spraying of MK at 1.5% showed an improvement of <em>E. coli</em> from minced beef and beef sausages that were less than 10 cfu g<strong><sup>-1</sup></strong>. Also the concentrations of yeasts and moulds were not detected at day 12 of storage. Hierarchically, sprayed MK extract gave best results than ground MK or MK extract form which shows effective inhibitor of lipid oxidation and microbial growth of beef sausages.</p>

Methicillin-resistant Staphylococcus aureus (MRSA) is known for serious health problems. Testing new inexpensive natural products such as mango kernel (Mangifera indica L., Anacardiaceae) may provide alternative and economically viable anti-MRSA drugs. In the current study, we screened clinical isolates from Aseer Central Hospital, Saudi Arabia, during 2012–2017 for MRSA and tested an ethanolic extract of mango kernel for anti-MRSA activity. Brief confirmation of MRSA was performed by the Vitek 2 system, while antibiotic sensitivity of strains was tested for their clinical relevance. The In vitro disc diffusion method was used to test the anti-MRSA activity of the ethanolic mango kernel extract. The antimicrobial activity of mango kernel was compared to that of standard drugs (oxacillin and vancomycin). Of the identified 132 S. aureus strains, 42 (31.8%) were found to be MRSA and their prevalence showed a clear increase during the last two years (2016-2017; p<0.001). MRSA strains showed 100% sensitivity to vancomycin, teicoplanin, linezolid, tetracycline, daptomycin, tigecycline, and tobramycin and 100% resistance to ampicillin and 98% to penicillin. The ethanolic extracts of mango kernel were found active against both S. aureus and the MRSA strains. Inhibitory activities (mean ± SE) were achieved at concentrations of 50 mg/mL (20.77 ± 0.61), 5 mg/mL (16.18 ± 0.34), and 0.5 mg/mL (8.39 ± 0.33) exceeding that of vancomycin (p=0.0162). MRSA strains were sensitive to mango kernel extracts when compared to vancomycin. Therefore, ethanolic extracts of mango kernel can be escalated to animal model studies as a promising leading anti-MRSA drug candidate and can be an economic alternative to high-priced synthetic antibiotics.
