Her research Bioaccessibility and health-promoting properties of hydroxycinnamic acids of coffee beans modified by roasting was rated among the top ten research projects in the PRELUDIUM scheme and was selected for dissemination by NCN.
The results of my research have shown that not only do both green as well as roasted coffee beans contain bioactive compounds beneficial to health, but also that the polyphenols in coffee reduce the pathogenesis of a number of chronic diseases of civilization, dr inż. Joanna Grzelczyk, adjunct professor at the TUL Institute of Food Technology and Analysis explains.
The laboratory tests were conducted on Arabica and Robusta unroasted (green) and light- and dark-roasted coffee bean extracts.
In vitro cell line studies of the tested extracts and their fractions have shown the highest biological activity primarily of green coffee preparations, including chlorogenic acid fractions, which acted cytoprotectively, protecting model enterocyte (Caco-2 and HT29), neural (SH-SY5Y), and pancreatic (MIN6 )cells from induced oxidative stress that promotes tumorigenesis, the researcher gave the main points of the research completed in 2022.
Her research was selected to help promote research funded by the National Science Center. Dr inż. Grzelczyk is featured in the printed calendar. Starting from May, information about her research will be available on the NCN website, social media profiles and networks, as well as in other information and promotional materials.
You can find out more about other health benefits of coffee consumption as reported in the blog post by professor Grażyna Budryn, head of the Institute of Food Technology and Analysis:
Recent years have been witness to the growing trend of consumers’ seeking minimally processed foods. Unroasted, green, coffee is one of the latest fads within that trends, alongside green tea.. One cup of green coffee contains up to 700 mg of antioxidants. Studies done at my Institute have confirmed that green coffee is more potent compared to roasted coffee in preventing Alzheimer's disease, type 2 diabetes and obesity, as well as in counteracting liver fibrosis and steatosis.
