The aim of the paper was to study how the process of aromatisation with marjoram affected the composition of volatile fraction and antioxidant properties of rapeseed oil. Different methods of aromatisation were used: direct addition of marjoram essential oil, classical macerations of marjoram herb, and maceration assisted with ultrasound or microwave. The dominant aromatic component in the volatile fraction was γ-terpinene with concentration in the range from 3.15 μg/mL (microwave assisted maceration) to 8.82 μg/mL (classic maceration with shaking). The content of this compound in the mixture of rapeseed oil with essential oil was 152.09 μg/mL. The sample aromatized by the direct addition of essential oil contained the highest amount of volatile substances but simultaneously it had the lowest antioxidant activity.

Background/objectives: Dementia is not a single disease but an umbrella term that encompasses a range of symptoms, such as memory loss and cognitive impairments, which are severe enough to disrupt daily life. One of the most common forms of dementia is Alzheimer's Disease (AD), a complex neurodegenerative condition influenced by both genetic and environmental factors. Recent research has highlighted diet as a potential modifiable risk factor for AD.

Potassium, an essential inorganic cation, is crucial for the growth of oil crops like L. Given the scarcity of potassium in soil, enhancing rapeseed's potassium utilization efficiency is of significant importance. This study identified 376 potassium utilization genes in the genome of ZS11 through homologous retrieval, encompassing 7 functional and 12 regulatory gene families.

Background: The BBR-BPC gene family is a relatively conservative group of transcription factors, playing a key role in plant morphogenesis, organ development, and responses to abiotic stress. L. (), commonly known as oilseed rape, is an allopolyploid plant formed by the hybridization and polyploidization of L.

Oil cakes are biomass wastes created by pressing oil from oilseeds. Their chemical composition (including high fat or protein content, a favorable fatty acid profile, and a high proportion of unsaturated acids) makes them valuable raw materials not only in animal feeding but are increasingly gaining popularity in biotechnological processes. This article examines the possibility of valorizing oil cakes using the lipid fraction extracted from them or their raw form in a two-pot biosynthesis process of GDDL-a cyclic ester with a creamy-peach aroma.
