The three sauces - barbecue, sweet chilli and sweet & sour - are produced by chef Lisa Tse in the Manchester restaurant's kitchen and have so far been sold through the restaurant and more recently through Chinese grocer Wing Yip.
Tse, who runs the restaurant with twin sister Helen, said they were pleased to now be able to sell the sauces, which contain no gluten, monosodium glutamate or artificial colourings, to a wider audience and get the Sweet Mandarin name out there.
"We are delighted to be launching our gluten free Chinese dipping sauces through Sainsbury’s, giving us national distribution with a partner who like us, believes food should be at the highest quality. We can't wait to work with Sainsbury's. It is a dream come true for a British manufacturer like us," she said.
Sweet Mandarin now joins a number of independent and chain restaurants in seeing their branded products go on sale in nationwide supermarkets.
