Indian food group Britannia Industries has reported a jump in half-year profits on the back of improved efficiency and higher sales.

The biscuit maker booked a 23.2% increase in net profit to INR796.5m (US$15.8m) for the six months to the end of September. Britannia's sales were up 19.6% at INR24trn.

MD Vinita Bali said Britannia had improved its efficiency and seen innovation drive improved sales.

"We continue to drive consumer off-take, cost effectiveness and operational efficiencies to generate profitable growth and, at the same time, have created a robust innovation funnel to fuel new growth," Bali said on Friday (11 November).
