Abstract
Glycation and the accumulation of advanced glycation end-products (AGEs) are known to
occur during the process of aging, as well as in individuals with diabetes and
neurodegenerative diseases. Elevated blood glucose levels diabetic patients lead to
increased formation of AGEs. A diet rich in bioactive food compounds, such as
polyphenols, has been found to have a protective effect. Foods abundant in phenolic
compounds have gained significant attention, representing a promising market and
capturing the interest of the scientific community, owing to their potential heath benefits
for individuals with diabetes. Notably, red fruits, dark green vegetables and green propolis
have emerged as particulary beneficial. However, it is important to inform individuals with
diabetes abot the advantages of consuming these foods in order to help regulate their
blood glucose levels, as the bioactive compounds they contain aid in controlling free
radicals. Thus, the aim of this study was to develop preparations using juice made from
red fruits, vegetables and, supplemented with green propolis, to assess the presence of
bioactive compounds and antioxidants, and to examine their sensory acceptance in
among people with diabetes. The total phenolic compounds, total flavonoids and
antioxidant capacity were assessed using the ABTS, DPPH and FRAP methods. The
results demonstrated a statistically significant increase (p<0.05) in all evaluated
parameters for the samples containing propolis compared to the control (juice without
added propolis). Sensory analysis conducted with 80 untrained individuals, indicated
that all samples received an approval rate of over 70% for all evaluated attributes, with no
statistical difference observed in the acceptance of the three formulations. Therefore, they
considered well-received by the participants. This study presents a product of high
nutritional value, exhibiting substancial antioxidant potential, and prossessing sensory
characteristics that are well-accepted by individuals with diabetes.
