This study aimed to investigate the physicochemical properties of beverage emulsions containing crocetin as a functional ingredient. The effect of different concentrations of gum Arabic (GA; 1-4%), various types of oils (10% sunflower or sesame oil containing 0.1% of crocetin) in the presence of xanthan gum (XG; 0.1%) were studied using a general full factorial design. The dependent variables were pH, opacity, size index, stability index (determined in accelerated and storage conditions), particle size, and steady shear rheological measurements. The main effects of GA concentration were significant (p < 0.001) on all of the physicochemical characteristics. However main effects of oil types were only significant (p < 0.001) on the mean diameter size, size index, and consistency coefficient () of prepared crocetin beverage emulsions. Results suggested sunflower oil may be more suitable for formulating a beverage emulsion containing crocetin because of the smaller mean particle size and lower size index.

We carried out limited enzymatic hydrolysis with trypsin on rice bran protein (RBP) pretreated by high hydrostatic pressure (HHP) in this study. The effects of the degree of hydrolysis (DH) on the structural and emulsifying properties were investigated. The results indicated that the molecular structure of RBP changed after limited enzymatic hydrolysis.

This study applied high hydrostatic pressure (HHP) treatment to buffalo milk casein to assess the influence of different pressure levels on its structural characteristics, physicochemical properties, and functional properties. The results showed that although HHP had no marked impact on the zeta potential and secondary structure, it altered the protein's spatial structure (primarily its tertiary structure), and improved dispersion properties (such as particle size, solubility, and turbidity), as well as foaming properties. Additionally, HHP improved the antioxidant activity and antibacterial activity against Escherichia coli.

Enzyme catalysis is important in food processing, such as in baking, dairy, and fiber processing and beverages. A recent advancement in catalysis is the development of Pickering emulsions as enzymatic catalytic systems; however, the use of Pickering emulsions (PEs) as catalytic systems in foods remains largely underdeveloped. Challenges exist that inhibit the widespread adoption of PEs as catalytic systems in foods.

Plant-based beverages are water-soluble extracts of cereals, pseudocereals, seeds and legumes that resemble milk in appearance. However, these products have important differences compared to normal liquid milk, such as nutritional composition, sensorial properties and shelf-life stability. Increasing number of consumers are opting for these beverages due to lactose intolerance, milk protein allergies or lifestyle.

Palm and palm kernel oils are preferred ingredients in industrial food processing for baked goods and chocolate-based desserts due to their unique properties, such as their distinctive melting behaviors. However, ongoing concerns about the social and environmental sustainability of palm oil production, coupled with consumer demands for palm oil-free products, have prompted the industry to seek alternatives which avoid the use of other tropical or hydrogenated fats. This project investigated replacing palm oils with chemically unhardened Swiss sunflower or rapeseed oils.
