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.

Objective

การเสื่อมสภาพของเซลล์จากอนุมูลอิสระเป็นสาเหตุหลักที่นำไปสู่การเกิดโรคเรื้อรังต่าง ๆ เช่น โรคมะเร็ง โรคหัวใจ และการเสื่อมสภาพของเซลล์ในระบบต่าง ๆ ของร่างกาย ดังนั้นการใช้สารต้านอนุมูลอิสระจากธรรมชาติจึงเป็นวิธีหนึ่งในการลดความเสี่ยงจากการเกิดโรคเหล่านี้ ขิง ปลีกล้วย และกระเจี๊ยบ เป็นพืชที่มีสารต้านอนุมูลอิสระและสารฟีนอลิกที่มีคุณสมบัติในการป้องกันความเสื่อมของเซลล์ อย่างไรก็ตาม สารเหล่านี้อาจสูญเสียประสิทธิภาพเมื่อสัมผัสกับปัจจัยภายนอก เช่น แสง ความร้อน และออกซิเจน ดังนั้นการใช้เทคนิคการห่อหุ้มสารด้วยวิธีลิโพโซม จึงช่วยเพิ่มความเสถียรของสารสำคัญและเพิ่มประสิทธิภาพในการนำส่งสารไปยังจุดเป้าหมายจึงเป็นสิ่งสำคัญ

Flow of Humane

This piece represents the collection of all human elements, applied to design for maximum efficiency, following the principles of Modern designers who embraced the famous phrase "Form follows Function." Every line and structure of the design is carefully considered for user comfort and practical use, while reflecting the idea that the user's experience is central to the design process. The beauty emerges from the harmony between function and form, not only meeting functional needs but also enhancing the aesthetic of Modernist design in a complete and meaningful way.

AI-Powered Security & Consumer Analytics, Integrating AI Vision for Enhanced Security and Consumer Behavior Insights in the Digital Era

In the digital era, Artificial Intelligence (AI) plays a crucial role in developing smart cities and enhancing business operations. Among AI-driven technologies, AI Vision Analytics has gained significant attention for Access Control Systems (ACS) and Consumer Behavior Analytics. This research focuses on integrating AI Access Control and AI Video Analytics to examine factors influencing Technology Adoption Behavior using the UTAUT2 (Unified Theory of Acceptance and Use of Technology 2) framework. Key factors assessed include Trust in Technology, Effort Expectancy, Social Influence, and Performance Expectancy, which impact users’ willingness to adopt AI-driven security and analytics solutions. The study also includes a real-world implementation of AI Vision Analytics at KMITL EXPO, where an AI-powered Access Control System and AI Video Analytics are deployed. The collected data is analyzed to identify trends in AI adoption for business management and security enhancement. The findings provide valuable insights for businesses and organizations to optimize AI Vision Analytics for enhancing security management and digital marketing strategies.
