Investigation of physicochemical and biological properties of bacterial cellulose & zein-reinforced edible nanocomposites based on flaxseed mucilage containing Origanum vulgare L. essential oil.

The researchers studied the effect of zein and bacterial cellulose on flaxseed mucilage/carboxymethyl cellulose composite. Zein improved the mechanical and barrier properties, while zein particles encapsulated oregano essential oil, delaying its release for extended antimicrobial effect.

LARVICIDAL AND FUNGICIDAL ACTIVITY OF THE LEAF ESSENTIAL OIL OF FIVE MYRTACEAE SPECIES.

This study extracted and characterized essential oils (EOs) from Myrtaceae species. EOs from Eugenia species had high larvicidal activity against Aedes aegypti, while S. cumini showed strong fungicidal effects. Chemical diversity in these EOs contributes to their different biological activities.

Characterization of the physicochemical properties of Lipu Colocasia esculenta (L.) Schott starch: A potential new food ingredient.

Lipu taro starch has lower amylose content and smaller particle size compared to cassava starch and wheat starch, resulting in superior emulsification properties and thermal stability, but inferior mechanical strength in gel formation.
