Abstract

Background: Figs (Ficus carica L.), widely valued in Asia and the Middle East, are recognized for their rich nutritional profile and medicinal properties, including potential anti-cancer and cardiovascular benefits. Both fresh and dried figs are abundant in fiber, trace minerals, antioxidant polyphenols, proteins, sugars, organic acids, and volatile compounds. This study aimed to evaluate the quality of fig jams prepared with three different sweeteners—white sugar, brown sugar, and honey. Methods: The jams were analyzed for their nutritional composition (fat, protein, fiber, vitamin C, carbohydrates, and total solids), chemical properties (titratable acidity and pH), bioactive compounds (total phenolic, flavonoid, and anthocyanin contents), and microbial safety (total viable count, yeast, and mold counts). Results: The findings revealed that honey fig jam had the highest acidity (0.048 ± 0.001), fiber (2.38 ± 0.002%), protein (5.95 ± 0.05%), and vitamin C (8.00 ± 0.1 mg/100g) content. White sugar fig jam exhibited the lowest moisture content (36.28 ± 0.28%) and ash percentage (0.70 ± 0.05%). The total soluble solids (TSS) were highest in brown sugar fig jam (67 ± 1.00%) and slightly lower in white sugar and honey fig jams (66 ± 1.00%). Significant differences (p < 0.05) in phytochemical compounds were observed among the samples. Conclusion: These results highlight the influence of sweeteners on the quality attributes of fig jam, with brown sugar emerging as a favorable option for optimizing both nutritional value, chemical quality and sensory properties. This study provides valuable insights for the development of fig-based products, contributing to the growing demand for functional foods.

Abstract

The global demand for landscape trees has been amplified with the increasing anthropogenic activity. South Korea has also witnessed a surge in demand for landscape plants, among others, Juniperus scopulorum gaining popularity for its ecological, economic, adaptability, and management attributes. However, the optimum management practice for high-quality Juniperus seedling production in South Korea remains unknown. This research was conducted on the one-to-two-years-old two cultivars of J. scopulorum, namely Blue Angel and Blue Heaven seedlings, to investigate the combined impacts of varying fertilizer concentrations (0 ppm, 150 ppm, 300 ppm) and biochar content (0% and 20%) under contrasting shading intensities (0%, 35%, 55%) and irrigation levels (200 ml, 400 ml, 800 ml). The study revealed that biochar and fertilizer amendment significantly (p < 0.01 and p < 0.05) enhanced the height and root collar diameter growth in Blue Angel and Blue Heaven in light shade intensity (0–35%) and higher irrigation (400–800 ml) conditions. Similarly, seedlings planted in 20% biochar and 300 ppm fertilizer yielded higher foliar, stem, and root biomass in low shade and higher irrigation conditions. The amount of shade and irrigation and their interactions significantly affected the morphological growth of seedlings for both cultivars, causing positive interaction with soil amendment (biochar and fertilizer application). These findings suggest that efficient seedling production of J. scopulorum management should focus primarily on light shading and moderate irrigation under biochar and higher fertilizer application. The research contributes valuable insights toward optimizing management practices and reducing costs associated with J. scopulorum seedling production in the region. Keywords: biochar, fertilizer, irrigation, Juniperus scopulorum, shading
