The study compared the chemical composition of various olive oils from the northern Algerian province of Bejaia. The research focused on the antioxidant activities of the oil's main constituents and their ability to inhibit the AKT1 protein, which is implicated in the development of colorectal cancer. The findings revealed that all of the examined oils fell within the extra virgin olive oil (EVOO) category and exhibited a high oleic acid content, particularly for samples from wild olives.

Epigenetic changes, host-gut microbiota interactions, and environmental factors contribute to inflammatory bowel disease (IBD) onset and progression. A healthy lifestyle may help to slow down the chronic or remitting/relapsing intestinal tract inflammation characteristic of IBD. In this scenario, the employment of a nutritional strategy to prevent the onset or supplement disease therapies included functional food consumption.

Over the past 20 years, the interest in Cannabis oily extracts for medicinal use compounded in pharmacy has consistently grown, along with the need to have preparations of adequate quality. Hot maceration (M) is the most frequently used method to compound oily solutions. In this work, we systematically studied the possibility of using an ultrasonic homogenizer and a sonotrode (US) as an alternative extraction method.

The therapeutic use of Cannabis oil extracts is constantly increasing. However, in Italy, they are allowed to be prepared with only a few methods and matrices. With this work, we aimed to assess how the different processes might affect the chemical composition of two different matrices (olive oils and medium chain triglycerides oils - MCT), accounting as variables for both the presence of Cannabis dried apices of the female flower and the adding of tocopherol acetate as an antioxidant.

Producers have to guarantee the extra virgin olive oil (EVOO) quality characteristics reported in the Regulation (CEE) 2568/91 throughout the product shelf-life (SL). Unfortunately, due to the development of oxidative reactions, some quality indices change during storage leading to a progressive deterioration of EVOO quality. To avoid the risk of product downgrading in the virgin oil category, the development of effective shelf-life prediction models is extremely important for the olive oil industry.

This study reports the blending at different levels (25, 30, 35, 40 and 45%) of Perilla seed oil (PO) with extra virgin olive oil (EVOO). Pure oils and blends were evaluated in terms of free acidity, peroxide value, fatty acid composition, sterols, tocopherols and biophenols content, oxidation stability, sensory acceptability and food pairing. Blends with high content of ω - 3 and ω - 6 fatty acids, biophenols, tocopherols, sterols and satisfying oxidation stability were obtained, representing products with improved nutritional properties.
