Investigation of the Optimal Ratio of Ginger, Banana Flower, and Roselle in Liposomal Encapsulation to Enhance Antioxidant Activity and Total Phenolic Content

Abstract

The growing interest in antioxidant-rich foods is driven by their potential to reduce the risk of chronic diseases such as cancer, cardiovascular conditions, and cellular degeneration. Ginger (Zingiber officinale), banana inflorescence (Musa paradisiaca L.), and roselle (Hibiscus sabdariffa L.) are herbal plants known for their high phenolic content, a crucial component in antioxidant activity. However, the bioactive compounds in these plants are often unstable when exposed to light, temperature, and oxygen, leading to a reduction in their efficacy. This study aims to investigate the optimal ratio of ginger, banana inflorescence, and roselle for encapsulation in liposomes—a technique designed to enhance the stability of bioactive compounds and improve their delivery efficacy. The research evaluates the antioxidant activity of the extracts using DPPH, ABTS, and FRAP methods, alongside total phenolic content (TPC) measurement. The most effective ratio for antioxidant activity will be selected for liposomal encapsulation, employing phospholipids as key structural components. The encapsulation efficiency (EE%) will be calculated to assess the effectiveness of the liposomal delivery system. The findings are expected to identify the optimal combination of ginger, banana inflorescence, and roselle that maximizes antioxidant potency and enhances the stability of bioactive compounds through liposomal encapsulation. This approach offers a promising strategy for developing herbal health supplements that maintain their biological properties over time.

Automatic Temperature and Humidity Control System for Small- Scale Household Oyster Mushroom Cultivation Houses

In the present day, interest in health and the consumption of chemical-free food has been steadily increasing, particularly in homegrown produce such as Phoenix oyster mushrooms (Pleurotus pulmonarius), which are highly nutritious and suitable for weight control. However, small-scale mushroom cultivation often faces challenges related to unsuitable environmental conditions, such as unstable temperature and humidity, which affect the growth and quality of the mushrooms. The development of an automatic temperature and humidity control system plays a crucial role in addressing these issues by utilizing sensor technology to monitor and adjust environmental conditions with precision. This helps enhance production efficiency, reduce human errors in manual control, and promote safe food production at the household level. Additionally, it helps lower production costs and supports the concept of sustainable living. The adoption of this technology is considered an important innovation in improving the quality of mushroom cultivation and increasing sustainability in food production.

Effective Removal of Dental Biofilm from Periodontal Pathogens Using DNase I and Engineered Human Antimicrobial Peptide D-LL-31: A Potential Mouthwash Solution

Aggregatibacter actinomycetemcomitans is a key pathogen in periodontal disease, damaging periodontal ligaments and alveolar bone through biofilm formation. D-LL-31, an engineered antimicrobial peptide, exhibits superior biofilm-killing ability compared to conventional treatments, while DNase I enhances its efficacy by disrupting the biofilm matrix. This study evaluated the combined effects of D-LL-31 and DNase I on A. actinomycetemcomitans biofilms. Results showed that D-LL-31 effectively eradicated biofilms, and its combination with DNase I further enhanced biofilm disruption without cytotoxicity to gingival epithelial cells. The D-LL-31 and DNase I combination shows potential for development as a mouthwash to improve oral health and combat periodontal disease.
