Title: Mario G. Albuja and Low-Density Edible Pet Chews.

Introduction

Mario G. Albuja is an inventor associated with Eureka, Missouri, and Societe des Produits Nestlé S.A. His patent work addresses the design and manufacture of edible animal chews, including products intended to support pets’ dental health.

Latest Patents

Albuja is named on 1 patent: “Low Density Edible Animal Chews and Methods of Making Same.” The invention describes pet chews with low density—about 1.0 kg/L or less—and a smooth exterior surface.

The patent outlines two approaches to producing these characteristics. One uses a modified extrusion die to increase shear and restrict surface bubbles. The other uses a modified extruder-screw profile that holds the dough longer, creating a whipping effect and more bubble-nucleation sites for a uniform cellular structure. Experimental testing reported better dental-cleaning scores for the puffed product than for a similarly formulated, unexpanded commercial dental chew.

Career Highlights

Albuja’s documented patent contribution focuses on food-processing techniques for pet products. The invention connects extrusion design and product structure with practical performance, offering methods for making lightweight chews with a smooth surface.

Collaborations

The patent information associates Albuja with Societe des Produits Nestlé S.A. and identifies Yannick Mahe as a coworker. Their connection reflects collaborative work in the development of edible animal chews.

Conclusion

Mario G. Albuja’s patent describes extrusion methods for producing low-density, smooth pet chews and reports promising dental-cleaning results for the expanded product.
