Marmalade, digital audio and bullet-proof vests are among the Scottish products showcased in the 2012 Queen's Awards for Enterprise unveiled today.
Mackays of Arbroath, the last authentic producer of traditional Dundee marmalade, wins an international trade award for the second time after hiking export sales by 150% in six years and hitting 23 new markets including Russia, India and China.
Mackays employs 130 and is focused on being global leader in traditional British marmalade after growing exports from zero in 1995 to 40% of its business.
Chairman Paul Grant, who took over the business 17 years ago, said: "I believe our flexibility with respect to the requirements of overseas markets has been paramount to our success, with special recipes created for markets such as Japan and Korea to ensure we're catering for local tastes."
Another international winner is J&D Wilkie of Kirriemuir in Angus, originally established in 1868 but now manufacturing technical textiles between the UK and China, and specialising in "Jack Ellis" ballistic vests. Overseas sales have more than trebled over the past three years.
One of two innovation awards is bagged by Linn Products, the Renfrewshire-based creator of 24-bit digital music players, while the other goes to Alba Sound, which employs 38 at the West of Scotland Science Park making underwater sonar devices.
Alba's Scottish Enterprise account manager Graeme Clark said: "Fighting off stiff competition from companies right across the UK is a tremendous achievement and one which the company should be extremely proud of."
There are 16 Scottish companies honoured in this year's awards, with 13 in international trade out of a total 151 UK awards.
Scotland has none of the individual awards for enterprise promotion and only two of the 50 innovation awards, but one of the eight awards for sustainable development goes to City Building, the former Glasgow council building services department, for its work on affordable energy-efficient housing.
The business incorporates the UK's largest supported factory, Royal Strathclyde
Blindcraft Industries, which offers employment and training opportunities for its disabled workforce and ex-service personnel, and also runs the country's biggest apprentice training scheme.
The business, industry and skills department said: "The standard of entries in this, the Queen's jubilee year, has been the highest ever, with nearly 25% of entrants gaining an award."
Five oil and gas supply companies are among Scotland's international winners, including Balmoral Comtec, a six-year-old technology offshoot of James Milne's Balmoral group. Its exports are 95% of turnover, or three times the sector average. The others are Brinker Technology, Downhole Products, Gaia Earth Sciences and Strategic Procurement (UK). Bridge of Weir Leather, the auto industry supplier, wins its fourth award, after increasing turnover significantly and lifting exports to 91%.
Edinburgh Instruments, one of the UK's leading manufacturers of high-end photonic and electro-optical instruments, is recognised for the first time. Alan Faichney, chief executive, said the firm was on track to lift turnover by £1.3 million to £9.5m this year.
The capital's financial sector also features in the shape of Barrie & Hibbert, the Edinburgh-based risk analysis specialist bought by Moody's in December.
The other international winners are Glencairn Crystal Studio of East Kilbride, Edinburgh-based Skyscanner, and hydraulics engineer White House Products, based in Port Glasgow.
