Abstract

Dragon fruit peel (DFP) which is typically discarded can provide a substantial amount of naturally occurring nutrients in low-fibre commercial white bread. The study evaluated physicochemical and sensory analysis of dragon fruit peel flour (DFPF) as a partial substitute for wheat flour in white bread formulations in following proportions: 0%, 3%, 6% and 9% (w/w). The measurements of the substituted breads involved crude fibre, ash, crude protein, fat, carbohydrate, moisture, volume, texture profile and colour profile along with sensory analysis. Based on chemical composition, DFPF was high in ash (11.60%), crude fibre (25.48%) and carbohydrate content (48.58%) however it was low in moisture (9.31%), fat (0.83%) and crude protein (5.15%). DFPF exhibits a brighter red colour due to the high values of L* and a*. As the DFPF level increased, the bread's ash and crude fibre content increased significantly, however the amount of carbohydrates decreased significantly. The bread's volume declined, while its moisture, density and hardness increased. Through sensory evaluation, the 6% DFPF was most favourable in terms of its appearance and texture. The addition of DFPF did not adversely affect the general appeal of the bread, indicating that it is a feasible way to increase the nutritious content of bread. In conclusion, DFPF can be used as a partial flour substitute to increase the nutritional value of white bread, particularly by increasing crude fiber content. The 6% substitution level provided the best balance of nutritional enhancement and consumer acceptance, indicating its potential for use in functional bakery goods.

Abstract

The treatment of diseases with synthetic drugs is often regarded as suboptimal and may cause side effects.Natural medicinal sources that are easy to obtain and affordable have therefore become a preferred optionfor many communities. Among plant groups, understory plants are among those most frequently examined fortheir medicinal potential. This study aimed to identify the diversity of understory plant species in the GunungPutri Block of Mount Ciremai National Park and to review their potential as medicinal plants. Understoryvegetation was surveyed using a plotted-line (belt-transect) method, with plots arranged along an elevationgradient at 100 m intervals, and the data were analysed using the Importance Value Index and the Shannon–Wiener species diversity index (H′). Medicinal potential was assessed through a literature review ofdocumented traditional uses and previously reported bioactive compounds, rather than throughphytochemical or pharmacological testing. The survey recorded 39 understory plant species, of which 16 wereidentified as having potential medicinal uses. Across all elevation intervals, the species diversity index fellwithin the range 1 ≤ H′ ≤ 3, indicating that the diversity of understory plant species in the study area ismoderate. Leaves were the plant part most commonly used for medicinal purposes, followed by roots, tubers,latex, and flowers. Ethnobotanical and laboratory validation is recommended as a follow-up study.

Abstract

In rapidly urbanising tropical landscapes, small sections of forest on campuses provide space for the protection of biological variety, learning in the field and the observation of ecological systems. For this study, researchers measured the variety of tree species plus the arrangement of the community within the UCS Forest at UiTM Puncak Alam, Malaysia. To collect data, five squares measuring 20 meters by 20 meters were placed along a line that started at a random point. When the researchers found woody plants, they counted the individuals, measured the width of the trunks at the height of a person's chest and determined the species - looking at physical forms, pictures, and also books. By using richness, Shannon-Wiener diversity, Simpson diversity & Pielou evenness, the researchers measured how many species were present and how they were distributed. As part of the examination of the community structure, the study also included rank abundance analysis, clustering with the Bray-Curtis method, heatmaps, indicator species analysis, as well as non-metric multidimensional scaling. There are 146 woody individuals in the records, and those plants belong to 73 species and 28 families. In each square, the number of species is between 17 and 27, or the Shannon-Wiener diversity values are between 2.69 and 3.26. If one looks at the Simpson diversity values of 0.89 - 0.96 and the Pielou evenness values of 0.87 - 0.99, it is clear that no single species is much more numerous than others; the distribution is balanced. By using multivariate analyses, the researchers found that the squares contain different groups of plants, which shows that the area is not uniform. Due to the results, the UCS Forest likely has a level of tree variety that is not low, and the area is a useful place for the campus to protect nature plus study ecology.
