Modernization is made enabled by the construction of an electrical power station. Thanks to this plant Petrinja has received electric lighting in 1907. With demand increasing by the day, a special salami production line is opened at the factory in 1912.
A newspaper advertisement of the time says:
“Well-known quality of its products gives a guarantee that I will serve our respected customers with only the best in every respect… and keep in stock every day, in addition to all kinds of dried meat, bacon and fat and 1-a salami, fresh frankfurter sausages, safaladas, Carniola sausages, Parisian sausages, Prague salami, blood sausage, etc., all immaculately fresh and delivered daily right from the factory.”
To commemorate the company’s 50th anniversary, journalists from several editorial offices of daily and weekly Zagreb newspapers visited the factory. Grandiose headlines follow the visit: From a small sausage factory to a large enterprise in central Europe, 50 years of intensive work, Domestic capital, National character of the factory.
60 wagons of salami, 20 wagons of lard and 5 wagons of cans are produced annually in Petrinja. Andrija Maurović designed the character of Jelica in image of the owner’s niece. It’s been on all Gavrilović products ever since.
World War II is over. The factory is confiscated and becomes public property. The Gavrilović family emigrates.
Gavrilović restarts export to Germany, Austria, Italy, Czechoslovakia and Great Britain. After World War II, Gavrilović was ready to expand its market and reestablish export ties with various European countries.
A new, modern factory opens. Increased production capacity enabled the opening of new workplaces for the local populace, contributing to economic growth of Petrinja.
Gjuro II Gavrilović returns to Petrinja as a technical advisor. That same year Gavrilović salami, Buđola, Petrinja sausages, Frankfurter sausages, Gavrilović pâté and Beef goulash were all awarded gold medals at the Zagreb Fair.
Gjuro III Gavrilović buys the bankrupted “Gavrilović”. This crucial moment marks a new beginning for Gavrilović, who retained its position as one of the most prominent producers of meat products in Croatia and beyond.
During 1995, production was re-established at the plant in Petrinja, which brought a new period of economic development to the Banija area.
