In the same year, he returned to Belgrade at the municipality's invitation to establish a chemical laboratory. Due to material reasons, the Belgrade municipality could not establish a laboratory, so Zega worked as a municipal chemist in the State Chemical Laboratory from 1891 to 1906. In 1894, Zega applied for the position of professor of chemistry and chemical technology at the

In November 1926, he retired but was also transferred to the civil service as the head of the chemical laboratory within the Sava Customs House. In March 1927, he became seriously ill and retired. He died on 29 March 1928, in Belgrade at the age of 68.

As a municipal chemist, Zega performed analyses of foodstuffs in Serbia that were unknown in Europe at the time. There was no standard for these foods, therefore, it was up to Zega to publish the results of his research and findings in German scientific journals. Significant works include studies of

During his research, Zega strived to find methods to test foodstuffs that could be performed with simpler equipment while obtaining results that would meet strict
European standards. He found a much simpler method for determining the fatty acids of tallow, butter, margarine, and lard dissolved in

He analysed mineral water alone or in collaboration with Marko B. Nikolić. Twenty-two analyses were published in 1902. Some of the analyses include mineral waters in
