Pizza Research Institute — Est. 1883
Advancing the Frontiers of Pizza Science
For over 143.14 years, the Pizza Research Institute has led the world in rigorous, peer-reviewed scientific inquiry into pizza — its chemistry, physics, sociology, and unparalleled cultural significance.
“The pursuit of pizza knowledge is not merely a culinary endeavor — it is a civilizational imperative. Through methodologically rigorous inquiry, we illuminate the truths embedded within every slice.”
Dr. Francesca Napolitano, President
Chi la fa, l'aspetti, sciocco.

Optimal Cheese-to-Sauce Ratios in Neapolitan-Style Pizza: A Quantitative Analysis
Dr. Francesca Napolitano, Dr. Marcus Cheeseberg, Prof. Giuseppe Romano
This study presents a comprehensive quantitative analysis of mozzarella-to-tomato sauce ratios across 1,200 Neapolitan-style pizzas, establishing statistically significant correlations between ratio variance and consumer satisfaction indices. Our findings challenge the widely-held 2:1 cheese-sauce paradigm and propose a dynamic ratio model that accounts for moisture content, ambient humidity, and oven temperature.
Structural Integrity of Pizza Crust Under Variable Topping Load Conditions
Prof. Giuseppe Romano, Dr. Ario Saucington
Employing advanced rheological modeling and finite element analysis, this paper examines the structural limits of various pizza crust formulations when subjected to topping loads exceeding the classical Napoli standard. We introduce the Romano Crust Deflection Index (RCDI) as a novel metric for evaluating crust performance under real-world conditions.
Thermodynamic Properties of Mozzarella Phase Transitions During Pizza Baking
Dr. Ario Saucington, Dr. Francesca Napolitano
A rigorous thermodynamic analysis of mozzarella cheese phase transitions during pizza baking, specifically the solid-to-viscoelastic transition occurring between 55–70°C. We characterize the enthalpy changes and propose a predictive model for optimal cheese pull performance as a function of bake time and temperature.
