Exploring bioactives of damson plums
Purple fruits such as plums are a rich source of bioactive compounds. These bioactive compounds, or phytochemicals, (such as vitamins A, C, and E, anthocyanins, and carotenoids), endow plums with a substantial antioxidant capacity. Certain bioactives are well-known for their anticarcinogenic, antimicrobial, antiallergic, antimutagenic, and anti-inflammatory properties. Consumption of these bioactives has been linked to health-promoting effects in humans. Consumer knowledge of validated health benefits may help increase consumer demand and product value.
Although information about some varieties of plums is available, the nutrient content and functionality of damson plums in New Zealand have yet to be quantified. The opportunity to investigate the range of bioactives in damson plums could inform further research opportunities towards commercialisation and export of damson plums, as well as the development of functional food products containing this fruit.
As a collaboration between Foot Steps Ltd and the Riddet Institute, this project aims to explore the nutritional and bioactive quality of damson plums towards understanding their functionality and potential use in functional food products.
The opportunity to create a value-add product through this project will in turn enhance land productivity by providing the opportunity to plant more damson orchards.
As a Māori business, Foot Steps Ltd aims to grow Māori knowledge, Māori scientists, and provide jobs for Māori in the future.

Dr Ali Rashidinejad
Dr Rashidinejad’s research focuses on the oral delivery of bioactive compounds (in particular, polyphenols) via functional foods.
While this generally lies in the development of methods/technologies that protect/encapsulate bioactives, Ali is specifically interested in the behaviour of bioactive compounds in the food matrix and gastrointestinal tract, with a focus on polyphenol-enriched functional food products.
