Zusammenfassung / Abstract

Goji berries (Lycium sp.) have a unique flavor, color, and nutritional value and are frequently advertised as “superfruit". Goji berries have been rarely analyzed for aroma compounds and sterols. The key aroma compounds in goji berries remain insufficiently characterized, and accurate quantitative data and reliable odor thresholds are lacking. Similarly, sterol data on goji berries were widely varied and inconsistent, and the lack of reference standards.

This work aimed to fill the existing gaps in knowledge and understanding of aroma and sterol profiles of goji berries with advanced extraction techniques. This work unraveled the mystery of odor contributor to the overall sensory profile of Lycium products with their labeled quality and included minor 4-methylsterols and 4,4-dimethylsterols.
