Title: Johannes Martinus De Bruijn: Advancing Industrial Lactic Acid Production

Introduction

Johannes Martinus De Bruijn is an inventor associated with Peterborough, Great Britain, and Purac Biochem B.V. His patent work addresses the use of concentrated raw sugar beet juice as a substrate for industrial-scale lactic acid fermentation.

Latest Patents

De Bruijn is associated with 1 patent, titled “Lactic Acid Production from Concentrated Raw Sugar Beet Juice.” The invention describes preparing raw beet juice by washing and cutting sugar beets, extracting the cossettes in water, removing the beet pulp, heat-treating the juice at 50–90°C, and concentrating it to at least 60 Brix. The concentrated juice is then diluted to the desired initial sugar concentration, supplemented with nutrients, and fermented using a lactic acid-producing microorganism.

The patent reports that beet juice concentrated to at least 60 Brix is storage-stable and relatively resistant to infections. It can serve as a fermentation substrate while producing lactic acid or lactate with yield, chemical and optical purity, clarity, and taste comparable to products made by fermenting white sugar.

Career Highlights

De Bruijn’s documented patent contribution focuses on adapting sugar beet processing for industrial fermentation. The approach uses concentrated raw beet juice as a practical feedstock for producing lactic acid.

Collaborations

De Bruijn’s listed coworkers include Diana Visser and Jan Van Breugel. His company affiliation is Purac Biochem B.V.

Conclusion

Johannes Martinus De Bruijn’s patent presents a method for using concentrated raw sugar beet juice in industrial lactic acid production, with reported product qualities comparable to fermentation using white sugar.
