Cebu Technological University (CTU) conducted Designing Experiments for Food Product Development Toward Scholarly Publication on November 26–28, 2025, bringing together researchers from across campuses for intensive training in product optimization through experimental design approaches.
The initiative aimed to boost food science research capacity and support faculty in producing publication‑ready studies.
On Day 1, Ms. Joy Doron of CTU‑Barili Campus opened with “Conceptualization and Experimental Design for Food Product Development,” followed by Ms. Joanna Christine Salinasal of Visayas State University (VSU), who discussed “Understanding Product Optimization: Concepts, Principles, and Relevance in Food Product Development.”
Mr. Jubymar A. Mabuto, also from VSU, spoke on “Introduction to Variable Screening through Plackett‑Burman Design,” concluding with a hands-on demo of screening analysis.
Day 2 featured Ms. Salinas again with “Optimization Designs using Response Surface Methodology (RSM): Mixture Design,” immersing participants in model fitting, surface plot analysis, and determining optimum levels.
Furthermore, Ms. Wenie Jean M. Labides of VSU followed with “Optimization Designs using RSM: Central Composite Design (CCD).”
On Day 3, Mr. Mabuto returned for “Verification of Optimized Formulations: Confirmatory Testing and Statistical Verification of Model‑Predicted Results,” moving toward the final discussion on “Application of Optimization Results: Translating Experimental Findings into Scalable Product Formulations and Quality Standards.”
Participants engaged in hands‑on workshops covering Plackett‑Burman Design with a volunteer demo on variable screening analysis, Mixture Design with a volunteer demo, verification and presentation exercises, and confirmatory verification of optimized formulations.
The workshops, organized by the Office of the Vice President for Research and Development under Dr. Pet Roey L. Pascual, provided participants with insights into mastering both theoretical frameworks and applied methodologies.
With this effort, the institution reinforced its pursuit of food innovation and impactful research output by equipping researchers with advanced experimental design methodologies.
