The objectives of the study were to evaluate the physicochemical characteristics of puddings fortified with 0.01% mandarin melon berry (Cudrania tricuspidata) and 0%–1.0% aronia (Aronia melanocarpa) extracts and to assess the effects of the fortification on consumer acceptance. The soluble solid content of pudding significantly increased as aronia concentration increased, whereas pH levels significantly decreased in a similar concentration‐dependent manner. The texture profiles of hardness, cohesiveness, and chewiness increased significantly in the pudding fortified with 0.01% mandarin melon berry extract compared to those of the control pudding, and these profiles decreased with increasing aronia concentration. One hundred consumers evaluated ten puddings, both with and without acid treatments, in two sessions. Overall acceptance, taste acceptance, and texture acceptance showed no significant differences until 0.1% aronia concentration was reached. However, these differences decreased significantly in the pudding fortified with 0.5% and 1.0% aronia extract. The results demonstrate that the potential application of mandarin melon berry and aronia extract fortification in pudding products should be limited to 0.01% mandarin melon berry and 0.1% aronia concentrations.

The aim of the present study was to investigate the quality characteristics of the aronia cultivar ‘Viking’ as affected by cultivation region. Aronia cultivated in 5 different regions (Danyang, Geochang, Gangjin, Gochang, and Ganghwa) was collected. pH, total acid, soluble solid, redness, total anthocyanin, total polyphenol, tannin, and organic acids were analyzed. Correlation analysis was also performed to determine the relationship between the quality characteristics of aronia and meteorological factors in each cultivation region. All variable assessed differed significantly among samples. pH ranged between 3.86-4.06. The highest pH was recorded in aronia cultivated in Gochang. Aronia grown in Ganghwa had the highest total acid, soluble solid, and total anthocyanin content and the highest redness. Malic acid, tartaric acid, and citric acid were detected in all aronia samples, with malic acid being the predominant organic acid in the aronia cultivars. Correlation analysis revealed pH and soluble solid content to have significant positive correlations with sunshine duration. However, redness showed a significant negative correlation with precipitation. Therefore, it can be confirmed that cultivation region play an important role in determining the quality characteristics of aronia ‘Viking’ from the results of this study.
The study was conducted to investigate quality characteristics and antioxidant activities of stick jelly prepared using 0, 25, 50, and 100% aronia juice instead of water. The moisture content of stick jelly was 81.88 to 88.22%, with the highest moisture content in jelly without the addition of aronia juice. The addition of aronia juice tended to decrease the moisture content of stick jelly compared to the control group. The ash and crude fat contents of the jelly increased with an increasing aronia juice content. The sugar content, total acidity, and hardness of the jelly increased, while the pH tended to decrease, with and increased aronia juice content. Regarding chromaticity, L* and b* values decreased, and a* values increased with an increasing aronia juice content. The total polyphenol and total flavonoid contents increased with an increasing aronia juice content. The antioxidant activity, measured based on the DPPH and ABTS radical-scavenging activities, and reducing powder were significantly higher in jelly containing the aronia juice than those in the control, and proportionally increased with an increasing aronia juice content. Overall, these findings suggest that aronia juice can be used for stick jelly making.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
