This paper studied the synthesis of calcium oxide (CaO) from snail shells by calcination, crushing, and grinding. Then, the sample was analyzed by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), specific surface area (BET), and particle size.

The objective of this study was to investigate the production of spinach concentrate. The research has shown that several factors affect the concentration process, including the ratio of vegetables to water in the grinding process, the content of potatoes mixed into the product, and the time of concentration.
