This study involved fortifying pumpkin slices with calcium and vitamin D3 using vacuum impregnation (VI) pre‐treatment and assessing the quality characteristics of the resulting desserts/jams. Slices were subjected to immersion or VI pre‐treatments for 30, 60, and 90 min in a solution containing calcium oxide and vitamin D3. Calcium ions contributed to the hardness of desserts, with VI reducing processing time. The highest impregnated calcium (58.17 mg/100 g fw) and vitamin D3 contents (6.02 mg/100 g dm) were determined in slices pre‐treated by VI for 90 min. VI was more effective than immersion in terms of calcium and vitamin D3 transition into pumpkin tissues. Scanning electron microscope (SEM) images indicated that calcium oxide particles were noticeable in slices pre‐treated by VI. Immersing fruit slices for 90 min produced desserts with a textural hardness of 11.04 N, while VI pre‐treatment for the same duration increased their hardness value to 18.92 N. Desserts produced with VI‐pre‐treated slices exhibited superior texture and sensory attributes, with no adverse taste resulting from calcium oxide. In conclusion, VI pre‐treatment shows significant potential for the industrial production of desserts/jams with enhanced structural integrity for fruits.

The recovery of CaCO3 from periwinkle shells as a precursor for the synthesis of CaO nanoparticles is validated in this work. The sol-gel synthesized CaO nanoparticles were characterized by XRD, FT-IR, UV visible spectrophotometer, SEM, BET and ICP instrumentation. Information obtained from the characterization showed that the material has a band gap of 4.12 eV, porosity in the mesoporous range (average pore size of 3.02 nm), crystalline size of 18 nm, BET surface area and pore volume of 220.11 m 2 /g and 8.43 cc/g respectively. The application of the nanoparticles for the separation of lead (II) from aqueous solution yielded results that indicated a strong dependency of the adsorption efficiency on decreasing temperature but increasing pH (up to 6.5), initial concentration of Pb 2+ , adsorbent dosage and period of contact.The interaction of concentration, time, temperature and adsorbent dosage indicated that optimum efficiency greater than 80% can be obtained at a temperature of 318 K, concentration of 250 ppm, an adsorbent dosage of 0.5 g and contact period of 75 minutes. Enhanced removal capacities (reaching almost 100% efficiency) were obtained under UV-activated adsorption experiments. The adsorbent showed an excellent ability to favourably adjust the pH, dissolved oxygen, alkalinity and conductivity of the contaminated water. It also displayed an appreciable tendency towards reusability and the total recovery of the adsorbed heavy metal ions from its surface. The pseudofirst-order kinetic, liquid film diffusion, Freundlich, Halsey and Elovich adsorption isotherms best fitted the adsorption process and confirmed the multimolecular adsorption layer with physical adsorption profile. Also, the adsorption of the heavy metal ions is limited by liquid film diffusion and supported surface heterogeneity and physical adsorption mechanism.
