Nutraceutical extraction and stabilisation
Various crops in Australia, such as chillis and avocados, have strong antioxidants and health-benefiting properties. We willl assess extraction solvents on various tissues by extracting from raw and freeze-dried material and assessing the antioxidant capacity using common assays (DPPH and ABTS). These extracts will be processed using freeze-drying and spray-drying, and the compounds of interest assessed for long term stability.

Extraction and formulation of astaxanthin produced in Phaffia rhodozyma fermentations
Traditionally derived from unsustainable petrochemicals, astaxanthin (AX) can also be sustainably produced by microbial fermentation. The yeast Phaffia rhodozyma naturally produces AX as its main fermentation product through sugar assimilation.In previous studies, we improved the bioprocess to produce (upstream) AX in P. rhodozyma. This project aims to investigate the extraction, recovery, and formulation (downstream) of the AX produced in our improved AX production process.AX is a carotenoid pigment and potent antioxidant naturally occurring in some ocean animals such as salmonids …
