Production of Cinnamic and p-Hydroxycinnamic Acids in Engineered Microbes [PDF]

open access: yesFrontiers in Bioengineering and Biotechnology, 2015
The aromatic compounds cinnamic and p-hydroxycinnamic acids (pHCAs) are phenylpropanoids having applications as precursors for the synthesis of thermoplastics, flavoring, cosmetic, and health products. These two aromatic acids can be obtained by chemical synthesis or extraction from plant tissues. However, both manufacturing processes have shortcomings,

Spouted bed drying parameters and adjuvant effects on polyphenol retention and antioxidant activity in mango peel powders

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Spouted bed drying of mango peels with colloidal SiO2 and corn starch produces a free‐flowing powder with reduced agglomeration, increased drying yield, and preserved antioxidant and polyphenol content. Abstract The production of polyphenol‐rich powders is a promising strategy for valorizing agro‐industrial byproducts. This study evaluated drying yield,

Edible Antifungal Coatings Based on Litchi Chinensis Seed Starch Enriched With Pericarp Procyanidins for the Postharvest Preservation of Strawberries

open access: yesFood Chemistry International, EarlyView.
Lychee starch coatings enriched with procyanidins showed strong antifungal activity and effectively preserved strawberry quality postharvest, reducing weight loss, decay, and senescence. This highlights their potential as a sustainable natural alternative for shelf‐life extension and fungal control in fresh produce.
