The levels of sugars, ascorbic acid, total phenolic content (TPC) and antioxidant activity (TAA) were determined in fruit juices from seven passion (Passiflora spp.) cultivars: P. edulis cultivars Purple, Frederick, Yellow, Pink, f. flavicarpa, maliformis quadrangularis (we also tested this cultivar's mesocarp).Purple Yellow had significantly higher sugar, 142.85 ± 0.17 g kg⁻¹ 139.69 0.12 kg⁻¹, respectively, than other cultivars. Glucose fructose juice vine-ripened fruits Frederick edulis,...

Seagrass meadows play a critical role in supporting coastal biodiversity and providing food habitats for other marine organisms but are continuously threatened by human activities, such as reclamation the maritime countries. The Sungai Pulai estuary harbours mangroves, mudflats, shoals with one of Malaysia's largest seagrass meadow (Merambong, Tanjung Adang, Laut) Johor, Malaysia. This study assessed environmental impact activities based on Landsat imagery (1994–2017) through mapping cover...

Although Southeast Asia is a hotspot of global seagrass diversity, there are considerable information gaps in the distribution beds. Broad-scale has not been updated database by UNEP-WCMC since 2000, although studies on seagrasses have undertaken intensively each region. Here we analyze recent tropical beds, their temporal changes, causes decline and conservation status (plus southern mainland China, Taiwan Ryukyu Island Japan) using data collected after 2000. Based 195 literature published...

Seagrasses are the only flowering plants (monocotyledonous Angiosperms) that have adapted themselves to living in marine and estuarine habitats, submerged most of time. They rooted sediments on sea bottom, with shoots appearing above substrate. occurred at 78 sites scattered west east coasts Peninsular Malaysia Sabah Sarawak East Malaysia. usually found along growing association shallow inter-tidal, mangroves, coral reefs, semi-enclosed lagoons shoals. In these seagrass beds or meadows...

Summary Several bioactive compounds from microalgae have demonstrated diverse biological activities with positive effects on human health. However, the potential of peptides as functional foods is still undervalued. Therefore, exploration strains sources could reveal strong and unique bioactivities, especially when these marine never been explored before. For this aim, protein extracts six indigenous diatoms were subjected to enzymatic hydrolysis using four proteases (flavourzyme, pepsin,...

Among leaf extracts, extract maliformis had significantly highest TPC strongest activity, whereas among stem showed amount possessed activity....

Marine angiosperms could inevitably offer considerable potential resources for their fiber, yet little research has been conducted, especially in Malaysia.Fiber characteristics of five species seagrass -Enhalus acoroides, Cymodocea serrulata, Thalassia hemprichii, Halophila ovalis, and spinulosawere evaluated.Fiber dimensions were studied to determine slenderness ratio, flexibility coefficient, Runkel's Luce's shape factor selection.The have the papermaking production as they possessed ratio...

This study presents a comprehensive comparative analysis of Terrestrial Laser Scanning (TLS) and Digital Close-Range Photogrammetry (DCRP) against traditional Total Station (TS) methods for 3D spatial documentation across range from 8.00 meters to 2.00 mm. The was conducted through three scenarios: Ground Control Points (GCPs), the Kafrelsheikh University Mosque, Kafr El Sheikh Tanta Road. Paired t-tests ANOVA revealed statistically significant differences (p < 0.05) all variables, with...

Methods to predict and fill Landsat 7 Scan Line Corrector (SLC)-off data gaps are diverse their usability is case specific. An appropriate gap-filling method that can be used for seagrass mapping applications has not been proposed previously. This study compared methods filling SLC-off with images acquired from different dates at similar mean sea-level tide heights, covering the Sungai Pulai estuary area inhabited by meadows in southern Peninsular Malaysia. To assess geometric radiometric...

This study focused on proximate composition, mineral content and organic acid properties of fruit juices from four Passiflora species; edulis (Purple), (Frederick), maliformis, quadrangularis the mesocarp quadrangularis.The moisture varied between 84.37±0.63% in P. (Frederick) to 86.63±0.33% ash was significantly lower (0.51±0.02%) than its juice (1.37±0.14%).Among species, (Purple) possessed higher protein, 2.81±0.19%and 2.40±0.11%,respectively.The fiber (8.49±0.40%)than other...

Enzymatic browning is a common limiting factor in the fruit industry because it causes significant losses through fresh product deterioration, affecting taste, flavor, and nutrition. Artocarpus odoratissimus, locally known as terap, an exotic indigenous to Borneo. This remains underutilized due its perishability, short shelf-life, peel browning. Currently, no information has apparently been published on mechanisms of A. odoratissimus. Thus, present study aims evaluate degree enzymatic...
