Article Synopsis
- Spray drying is a common method used to preserve bioactive ingredients and improve their storage stability, and this study investigated creating plant-based spray-dried powders using hemp, canola, and flax seed proteins combined with maltodextrin.
- The research assessed the oil-seed proteins' nitrogen solubility, emulsification, and foaming capabilities, along with analyzing the encapsulation process based on yield and efficiency.
- Results showed that the plant-based powders had a yield of 75.0% to 78.5% and efficiency levels of 58.4% to 77.5%, demonstrating that these powders have comparable characteristics to traditional whey protein powders, indicating the potential of oil-seed proteins in this application.

Article Synopsis
- Chaga mushroom, a fungus primarily found on birch trees, has been recognized for its traditional use in cancer treatment, and this study explores its chemical makeup and effectiveness against various cancer cells.
- The research identifies key compounds in chaga extracts, such as inotodiol and betulinic acid, and evaluates their cytotoxic effects on 31 human cancer cell lines using a specific testing method.
- Results indicate that chaga extracts display moderate anticancer activity, with stronger effects from those growing on specific birch species, particularly against HepG2 and CAL-62 cancer cell lines, suggesting chaga's potential as a source of anticancer compounds.
The wine industry generates large quantities of by-products each year. Therefore, this work aimed to isolate and evaluate the oil and protein fractions of Japanese quince (, JQ) press residue, offering a partial utilization of valuable bioactive compounds of wine industry by-products. To study the JQ oil extract yield, composition and oxidation stability, we modified the co-solvent composition during the supercritical CO (SC-CO) extraction of oil by adding different ethanol content.

- Inonotus obliquus is a fungus that causes stem rot on certain tree species, notably in Estonia, where it is commonly found on Betula and Alnus.
- The study focused on analyzing the bioactive compounds in I. obliquus conks from three tree species: Alnus incana, Alnus glutinosa, and Betula pendula.
- Results showed differences in compounds, with Alnus incana having higher betulinic acid content, while Betula had more polyphenols; this research highlights the potential for cultivating I. obliquus on Alnus to enhance its economic value.
This study aimed to identify promising candidates of rowanberry cultivars for a wider cultivation and utilization. Antioxidant properties and phenolic content were evaluated for fruit, juice, and pomace samples of 16 different sweet rowanberry cultivars (cvs) and wild rowanberry ( L.), while the antioxidant potential was assessed using three different methods, based on the capacity to scavenge ABTS and DPPH and measure the oxygen radical absorbance capacity (ORAC).

In addition, several polyphenols, such as phloretin, also have potential antiviral effects, making these compounds potential ingredients of biofunctional foods. A promising source for the extraction of phloretin is a by-product of apple production-apple tree leaves.
