Fermentation of cocoa pod husks with for food applications.

Cocoa pod husks (CPHs), the major side-stream from cocoa production, were valorized through fermentation with (PSS). Considering ergosterol as a biomarker for the fungal content, the mycelium accounted for 54% of the total biomass after 8 days in submerged cultures. The crude protein content of fermented CPH (CPHF) increased from 7.

Distribution and transition of aroma-active compounds in dark chocolate model systems under conching conditions.

Understanding mechanisms inside the conche is inevitable for targeted conching. Therefore, distribution and transition of aroma-active volatiles (acetic acid, benzaldehyde, (R,S)-(±)-linalool, 2,3,5,6-tetramethylpyrazine, 2-phenylethanol, and 2-phenylethyl acetate) between the different components of dark chocolate (cocoa butter, cocoa particles, sugar particles) were studied. Different model systems were designed and aroma-analytically analyzed by stable isotope dilution analysis.

Thermal stabilisation of cocoa fruit pulp - Effects on sensory properties, colour and microbiological stability.

To improve cocoa pulp's shelf-life, preservation processes are necessary while maintaining the quality of the pulp. We applied pasteurisation and UHT-treatment and investigated different quality parameters: dry matter content, water activity, total soluble solids, colour and peroxidase activity. Both technologies inactivated peroxidase successfully.

Peripheral Amino Acid Appearance Is Lower Following Plant Protein Fibre Products, Compared to Whey Protein and Fibre Ingestion, in Healthy Older Adults despite Optimised Amino Acid Profile.

Plant-based proteins are generally characterised by lower Indispensable Amino Acid (IAA) content, digestibility, and anabolic properties, compared to animal-based proteins. However, they are environmentally friendlier, and wider consumption is advocated. Older adults have higher dietary protein needs to prevent sarcopenia, a disease marked by an accelerated loss of muscle mass and function.

Aroma-active volatiles and rheological characteristics of the plastic mass during conching of dark chocolate.

Chocolate conching is a highly complex, thermomechanical process that transforms the aroma and flow properties of a dry starting material. Different conched plastic masses of dark chocolate were characterized. Rheological characterization of plastic masses was performed for the first time using a closed cavity rheometer (CCR).
