Adding excipients is an important method to change the flavor and biological activity of food materials during processing. In this study, the contents of 11 bioactive compounds in the mulberry leaf tea with or without processing by addition of honey or salt, and their absorption and elimination characteristics in rats were determined. The biological activities of processed products were studied by in vitro models, and the effects of different processing methods on the compounds and biological activities of mulberry leaf tea extracts were analyzed by multiple factor analysis. We found that different processing methods can change the contents of some compounds in mulberry leaf tea extracts, and then affect the biological activity of extracts. The processing method of adding honey and salt can respectively enhance the antioxidant capacity and anti-apoptotic effect of mulberry leaf, while the processing method without auxiliary materials was more conducive to the repair of blood vessels.

The global goat population continues to grow, and simultaneously, fodder demand is increasing, despite the fact that feed resources are limited, and thus, new unconventional feed resources should be explored. The present study focuses on the nutrient utilization of ten top feeds viz. Acacia nilotica, Celtis australis, Ficus palmata, Ficus religiosa, Grewia optiva, Melia azadarach, Morus alba, Quercus incana, Salix alba and Zizyphus jujuba.

The objective of this study was to formulate Pickering emulsions stabilized by transglutaminase cross-linked mulberry leaf protein (TG-MLP) nanoparticles as a delivery system for curcumin (Cur) and to assess its bioaccessibility both in vivo and in vitro. The encapsulation efficiency of curcumin in high-internal-phase Pickering emulsions (HIPEs) prepared at pH 10 with a 20 mg/mL concentration of TG-MLP reached 93%. Compared to Oil-Cur, Cur-HIPEs exhibited superior antioxidant activity.

Objective: This study aimed to formulate leaf extract (MAE) loaded solid lipid nanoparticles (SLNs) and investigate its cytotoxic potential using MDA-MB231 cell line.
Significance: SLNs can protect MAE from degradation, enhance cytotoxicity potential, and making them suitable for various therapeutic areas.
Methods: SLNs were developed using high-pressure homogenization method, and the formulations were optimized based on particle size, zeta potential, % entrapment efficiency (EE), and % cumulative drug release (CDR).

In December 2017 the Venetian Region (local Authority), financed the creation of the Operational Group (OG) 'Serinnovation', within the framework of the Rural Development Plan supported by the European Community. The OG aims at coordinating and spreading innovation in sericulture through mechanisation of processes and centralisation of some rearing steps, the use of waste as by-products and traceability to promote local productions. The project acts on perceived quality by increasing the added value, through production cost efficiency, and on the recovery of the waste material for further applications (circular economy).

Introduction: Type 2 diabetes (T2D) is a metabolic disorder marked by disruptions in glucolipid metabolism, with numerous signaling pathways contributing to its progression. The liver, as the hub of glycolipid metabolism, plays a pivotal role in this context. Mulberry leaf (ML), a staple in traditional Chinese medicine, is widely utilized in the clinical management of T2D.
