The biggest part of this £455m market, salad accompaniments, has driven this growth, up 18.2% year-on-year, and now represents a 32.9% value share. With volume growth at a lower rate of 8% this reflects both an increase in prices of the leading brands ­ Heinz Salad Cream and Hellmann's Mayonnaise, and the launch of premium priced salad dressings. The other dominant sector, thick and thin sauces with a 30.9% value share (38.5% volume) has undergone more marginal growth at 2%. Heinz Tomato Ketchup remains the branded leader within this sector, and the total market . With the exception of condiment sauces, which has grown in value terms by 8.6%, all other sectors ­ mustard, pickles and vinegar ­ remain stagnant. In terms of consumer dynamics, 98% of all GB households have purchased a table sauce or pickle product in the latest year, with buyers purchasing, on average, once every three weeks, when they spend £1.21. Despite such a high penetration level suggesting the market could be saturated, both branded and private label innovation continues. Heinz has recently launched Kids and Organic Tomato Ketchup, Green Sauce, and a range of table sauces while many own label players have developed new lines. When it comes to share of trade, Tesco takes the lion's share of the market with 25.6%, and Sainsbury is in second place. In volume terms, however, Asda commands a greater share than Sainsbury at 16.7% compared to 15.7% and thus secures the number two slot behind that of Tesco. {{FOCUS SPECIALS }}
