The deal, which includes Burton's Liquorice Allsorts and Dolly Mixture plant in Blackpool and its 180 staff, will see Tangerine's turnover increase from £45m to nearly £60m.
Chairman Steven Joseph said: "This is a great opportunity. The products and expertise are an excellent fit with our business and development plans."
Tangerine was created in January this year when it bought and renamed Toms Confectionery. The latest deal brings the number of sites it owns to four, and swells its workforce to 630.
Chief executive Steve Dodds said the purchase was part of the company's plans to become a £100m business within five years. As well as growing organically, he revealed it was looking for more acquisitions and did not rule out a move into chocolate.
