Synergistics of Bioactive Compounds in Underutilized Fruit Syzygium Aqueum Using GC-MS and Sensorial Profile of Value - Added Fruit Preserves

Abstract

Introduction: Countless research has been executed universally on various underutilized fruits. Syzygium aqueum, (watery rose apple) a plant of the Myrtaceae family with enormous therapeutic properties, has the potentiality to treat an extensive array of illnesses.

Objectives: In the current study, Gas Chromatography-Mass Spectrometry (GC-MS) analysis was employed to identify the bioactive components in methanol extracts of Syzygium aqueum fruit. As the fruit is enduring underutilized, an urgent need to focus on the assortment and promotion of underutilized fruits are necessary through the development of value-added products.

Methods: The GC–MS analysis of the fruits of Syzygium aqueum was carried out using a GC–MS version (QP 2010 Plus, Shimadzu). Five types of value-added products specifically summer drink (SASD), murabba (SAM), wine (SAW), fruit spread (SAFS) and pickle (SAP) were formulated and standardized

Results: Organoleptic evaluation was administered on all the developed products and the results indicate that SASD was highly acceptable (4.86 ± 0.34) among all other watery rose apple products followed by SAM (4.76 ± 0.43), SAFS (4.76 ± 0.43), SAW (4.73 ± 0.44), and SAP (4.60 ± 0.47). 28 compounds in fruit were discovered during GC-MS study, with 4H-Pyran-4-one, 2,3-dihydro-3,5-dihydroxy-6 methyl (6.03%), 2,2'-Bioxirane (5.42%), cis-Calamenene (5.25%), including n-Hexadecanoic acid (3.30%) being the primary constituents. However, the compound with the highest percentage (6.03%) of peak area was 4H-Pyran-4-one, 2,3-dihydro-3,5-dihydroxy-6 methyl.  

Conclusions: The majority of bioactive substances were documented to have an array of activities, comprising antioxidant, anti-inflammatory, anti-allergic, anti-cancer as well as anti-hyperglycemic properties. The findings of this study offer clear knowledge regarding the diagnostic aid of the fruit and shows significant phytopharmaceutical value. Besides from helping to promote numerous health advantages, value addition to Syzygium aqueum fruits will increase utilization by various communities and reduce post-harvest losses.
