The Moroccan picholine tree’s leaves contain phenolic compounds that benefit human health. However, the amount and type of these compounds can vary based on factors such as the extraction method and conditions. This study aimed to improve phenolic compounds’ extraction while minimising harmful chemicals’ use. It has been found that using ethanol as...

As a result of the growing demand for low-calorie sweeteners, interest in stevia plant has increased. Two methods are applied for the preservation of stevia leaves: freeze drying and gamma irradiation at 1 kGy. Because most studies have focused on sorption characteristics of plants, the present work aims to evaluate the effect of these two technolo...

The legume by-products of broad beans, artichokes and peas seem to be of little nutritional value. However, further analysis shows the presence of phenolic compounds, pigments; proteins, lipids and polysaccharides. The present study extended on the one hand to follow the classic drying kinetics in a ventilated oven of the powder of the bean peel, t...

Argania spinosa L. Skeels is an emblematic tree in Morocco, known worldwide for its medicinal and nutritional value. Its fruits contain kernels used to prepare an edible oil, the leaves are used to feed livestock, and its wood is used as fuel. If the oil acquires high importance, the other components of the fruit of the argan are undervalued. Our o...

The caper is a thorny shrub, a plant very widespread in the countries of the Mediterranean basin. In Morocco it is widely cultivated in three main regions, the city of Taounate, the city of Safi and Tardounate, also in several other regions in a spontaneous state. In this study the objective is to study the caper genus (Capparis spinosa L.) belongi...

The effect of freeze-drying and gamma irradiation at 0.5, 1, and 2 kGy on the physicochemical composition (moisture, fat, ash, mineral, and chlorophyll contents), microstructure, total phenolic content, and antioxidant capacity of stevia leaves was investigated in the present study. The results obtained indicated that freeze-drying and gamma irradi...
