Jamba Juice has said that it expects to have a further 80 outlets open globally by the end of the year.

The US smoothie maker, which narrowed its net losses in the first half of 2011 as a result of international store expansion, has entered three new markets this year - Korea, the Philippines and Canada. As of 4 October, the firm said it has opened 752 locations globally and intends to open a further 80 by the end of 2011.

Stores opened include 586 "traditional" and 166 "non-traditional" venues. Jamba opened its first store in Toronto, Canada and nine franchise locations in South Korea last week.

The company said it is testing "a new growth concept" called 'JambaGO' - "an express service with a limited menu of the brand's most popular smoothies". The concept is designed to rapidly expand the firm's brand presence, it said. Jamba currently has 15 JambaGO units in test in the US.
