While touring Europe in 1979, Alfredo Yao learned about the Doypack packaging format in one of the European trade exhibits he visited.

He put up a company called SEMEXCO Marketing Corporation and launched Zest-O orange juice drink in 1980.

[citation needed] To date, the company also exports mango purées to China, Australia, New Zealand, Korea, Singapore, the United States, and Europe.

Early in 2010, the company ventured with PT Kalbe Farma Tbk of Indonesia into the manufacture of a new line of energy drinks, said to be the largest pharmaceutical industry category in Southeast Asia.

The new venture recently introduced to the Philippines, Indonesian and New Zealand markets its new line of energy drink called “Extra Joss”.
