A reliable and sensitive technique using silver nanoparticle (AgNPs) was developed for the detection of melamine in milk sample. The AgNPs was synthesized using culinary banana peel extract (BPE) where pH, temperature, the amount of concentration of BPE and concentration of AgNO3 was standardized. The effect of the parameters used for the synthesis of AgNPs was analyzed by observing the colour of reaction mixture and surface plasmon resonance. The AgNPs synthesized under optimum conditions were characterized by SEM-EDX, TEM and FTIR. FTIR studies reveal the effective conjugation between AgNPs and bioactive components of BPE and formation of spherical and regular shaped AgNPs were confirmed by TEM images. Presence of Ag as a dominating metal in AgNPs confirmed the formation of AgNPs. The level of melamine above 0.5 mg/L in milk could easily be detected through the interference synthesis of AgNPs.The aim of the present study was to develop purple passion fruit powder using the foam mat dried process. click here The possible effect of whipping time, methylcellulose concentration, and drying temperature on physicochemical and phytochemical properties of foam mat dried passion fruit was evaluated and compared with fruit pulp. The drying process was optimized using central composite design and optimum conditions were whipping time 2.78 min, methylcellulose 2.58%, temperature 44.05 °C. At the optimum condition vitamin C, total phenolic compound and hygroscopicity were 34.67 mg/100 g, 258.12 mg GAE/100 g, and 21.12%, respectively. The artificial neural network was applied to predict experimental outcomes. The phytochemical properties in terms of (±)-α tocopherol, D-α-tocotrienol, β-carotene, and phenolic acid were determined using RP-HPLC. The foam mate dried powder contained a higher amount of β-carotene (13.26 mg/100 g), total phenolic compound (258.12 mg/100 g) and phenolic acids than fruit pulp whereas fruit pulp was contented higher amount of (±)-α tocopherol (171.1 mg/100 g) and D-α-tocotrienol (27.19 mg/100 g). The study manifested foam mate drying as an effective way to develop passion fruit powder.In this present study, solid desiccant-based pressure-swing adsorption (PSA) dehumidifier was developed and the process parameters were optimized to deliver the air continuously at 0.1% relative humidity. Mint (Mentha arvensis) leaves are tested to study the drying characteristics at varied flow rates of dehumidified air in the drying chamber. The initial moisture content of 5.059 g water/g dry matter have been reduced to a safe storage level in 360 min at 0.160 m3/min volume low rate. The effective moisture diffusivity of the mint leaves was found in the range of 2.07534 × 10-11m2/s to 3.45817 × 10-11m2/s. The percentage of retention of ascorbic acid in dried mint leaves is increased by an increase in the volume flow rate of dry air and a maximum of 70.11% is achieved by 0.160 m3/min. The colour measurement and chlorophyll content of the dried samples indicated that the desiccant dehumidified air dryers are suitable for heat sensitive green leafy vegetables.Cashew apple extract (CAE) is a product with intense yellow color obtained from residual fibers of juice processing. Although CAE is known to be rich in carotenoids and anacardic acids, the biological activities of this potential natural food colorant remain unexplored. The present study is the first to investigate the toxicity, antiproliferative and antimicrobial activities of the lyophilized CAE (L-CAE) and its encapsulated products, using maltodextrin (M-CAE) or cashew gum (CG-CAE) as carriers. In addition to their high carotenoid content, the phenolic contents in all materials was determined using UPLC-QTOF-MSE. The acute toxicity was performed using adult zebrafish (Danio rerio); antiproliferative activity was assessed using seven different human tumor cell lines [U-251 (glioblastoma), MCF-7 (breast, adenocarcinoma), NCI-ADR/RES (multidrug-resistant ovarian adenocarcinoma), NCI-H-460 (lung, large cell carcinoma), PC-3 (prostate, adenocarcinoma), OVCAR-3 (ovarian adenocarcinoma), and HT-29 (colon, adenocarcinoma)] and an immortalized human keratinocyte (HaCaT) while the antimicrobioal activity was evaluated on Staphylococcus aureus ATCC 25923, Listeria monocytogenes ATCC 19115, Escherichia coli ATCC 25922 and Salmonella Typhimurium ATCC 51812 microorganisms. Both lyophilized and encapsulated CAE samples did not exert acute toxicity against zebrafish neither antiproliferative effect against human tumor and non-tumor cell lines. Further, L-CAE showed potential antimicrobial activity against Listeria monocytogenes, which was confirmed using electron microscopy. The current findings demonstrated that CAE is a potential source of bioactive compounds to use as an additive in the food industry.In order to examine bee pollen hydrolysates to assess their anticancer and antioxidant properties, hydrolysis of bee pollen was first performed using three different commercially available enzymes Alcalase®, Neutrase®, and Flavourzyme®. The study used DPPH and ABTS assay to evaluate the antioxidant properties of the hydrolysates obtained from bee pollen. All of the tested hydrolysates demonstrated antioxidant activity, while hydrolysate based on Alcalase® offered a high value for IC50 and was therefore chosen for further separation into five sub-fractions via ultrafiltration. The greatest antioxidant activity was presented by the MW  less then  0.65 kDa fraction, which achieved an IC50 value of 0.39 ± 0.01 µg/mL in the DPPH assay and 1.52 ± 0.01 µg/mL for ABTS. Purification of the MW  less then  0.65 kDa fraction was completed using RP-HPLC, whereupon the three fractions from the original six which had the highest antioxidant activity underwent further examination through ESI-Q-TOF-MS/MS. These particular peptides had between 7 and 11 amino acid residues. In the case of the MW  less then  0.65 kDa fraction, testing was also carried out to determine the viability of lung cancer cell lines, represented by ChaGo-K1 cells. Analysis of the antiproliferative properties allowed in vitro assessment of the ChaGo-K1 cells’ viability following treatment using the MW  less then  0.65 kDa fraction. Flow-cytometry generated date which revealed that it was possible for the MW  less then  0.65 kDa fraction to induce apoptosis in the ChaGo-K1 cells in comparison to the results with cells which had not been treated.
