Abstract

The bromelain-enzymatic reaction is applied in virgin coconut oil (VCO) production. Hydrolysis of the emulator by bromelain enzyme in coconut milk during fermentation maximized further the separation of oil and water. In the higher demand for VCO in many industries, the VCO stability during transportation and storage must be evaluated.  The research aims to evaluate the physical and chemical stability of the effect of temperature in the storage. VCO's physical and chemical stability was evaluated under two different temperature and storage periods: an elevated temperature of 50°C for 10 days and room temperature (27-30°C) for 50 days. The storage was conducted in a clear glass bottle. The evaluation was based on physical and chemical stability tests before and after storage, including organoleptic, pH changes, density, viscosity, acid number, peroxide number, and saponification number. Based on the data, the quality of the VCO after storing at 50°C for 10 days and 27-30°C for 50 days was found to be changed for pH, specific gravity, viscosity, acid number, peroxide number, saponification number, while for the appearance was found to be no changes. The VCO was very sensitive to environmental effects. Therefore, it is necessary to find the best storage chamber and temperature for stabilizing the VCO.

Abstract

Lips are susceptible to ultraviolet (UV) exposure because they lack melanin, sweat glands, and hair follicles. To protect and moisturize lips, lip balm is widely used; however, it generally contains synthetic ingredients that can cause side effects. Therefore, a safe and effective natural-based alternative is needed. Pineapple peel (Ananas comusus L. Merr.) contains flavonoids and tannins that function as natural sunscreens. In contrast, carrot peel (Daucus carota L.) is rich in β-carotene, vitamin E, and flavonoids with antioxidant and natural coloring properties. The combination of these ingredients is considered complementary and has the potential to be used as natural active components in lip balm formulations. This study aims to determine the formulation and SPF value of lip balms containing pineapple and carrot peel extracts as UV protection agents. Four formulations were prepared: F0 (0% extract), F1 (10% pineapple peel extract), F2 (10% carrot peel extract), and F3 (combination of both extracts). The evaluation included organoleptic testing, homogeneity testing, stability testing, determination of the melting point, pH measurement, and SPF testing. Data were analyzed using the Kruskal-Wallis test method. The results showed that all formulations met the characteristics of a good lip balm, with SPF values of 1.028, 8.791, 8.949, and 25.672, respectively. Formulation F3 showed the highest SPF value with “ultra” protection, indicating strong potential as a natural UV-protective lip balm. Keywords:  Pineapple peel, carrot peel, lip balm, formulation, SPF value.

Abstract

Soil salinization is a significant constraint to global food security, with rice (Oryza sativa L.) being particularly prone to salinity stress. As a sustainable mitigation approach, plant growth-promoting rhizobacteria (PGPRs) are potential candidates for improving crop tolerance. This study investigates the performance of PGPR strain Enterobacter cloacae UIA3, noted for producing indole-3-acetic acid and nutrient solubilization, in establishing a symbiotic relationship with rice under salinity conditions. Three rice varieties, Pokkali, MR297, and IR64, under four salinity levels (0, 50, 100, and 150 mM NaCl) were analyzed for physiological response and symbiotic compatibility. A host-specific interaction was observed where the salt-tolerant Pokkali variety showed a strong positive association through enhanced root hair development and significant improvement in the growth of inoculated plants under stress. However, the salt-sensitive varieties of MR297 and IR64 showed severe root damage and exhibited minimal bacterial colonization. This indicates that the performance of E. cloacae UIA3 is effective mainly as bio-inoculation in salt-tolerant rice genotypes. Thus, host specificity is indispensable in the microbial strategy for saline agriculture. Overall, the results highlight avenues for PGPR strain E. cloacae UIA3 as an environmentally friendly bioinoculant under saline environments.
