This research had objectives to study the proper amount of adding of unused water melon peel in products of tomato sauce chili sauce pizza sauce and seafood sauce. This research studied the nutritional value of sauce products and studied the acceptance of consumers towards sauce products. The test found about the study about proper amount of unused water melon peel in four kinds of sauce products. The researcher tested about acceptance of forty examinees who are instructors in field of Food and Nutrition majoring Food and Nutritional science and majoring Food Service Industry by using 9-point hedonic scale by adding water melon peel into tomato sauce at levels of 5 10 and 15 per cent of all ingredients It is found that the examinees accepted chili sauce at level of 15 per cent that is in the much favor level (8). The chili sauce has been added with water melon peel at levels of 3 6 and 9 per cent of total ingredients. It was found that the examinees accepted it at level of 9 per cent that was from the level of moderate favor to much favor (7-8). The examinees accepted pizza sauce which has been added with water melon peel at level of 10 20 and 30 per cent of all ingredients. It was found that examinees accepted at level of 30 per cent which was in the level of much favor (8). The examinees accepted seafood sauce which has been added with water melon peel at level of 10 20 and 30 per cent of all ingredients. It was found that examinees accepted at level of 20 per cent which was in the level from moderate to very much favor (7-8). When the researcher studied the physical features of sauce product it was found that pH value at which was 25 degrees Celsius was in range of 3.90 3.49 3.83 and 2.73. The viscosity value was 4650cp 32639cp 37760cp and 612cp or centipoints respectively. Nutritional value of sauce product it was found that tomato sauce which has been added with water melon peel for 15 per cent has total calory for 70 per cent protein for less than 1.25 per cent fat for 0 per cent ash for 1.43 per cent carbohydrate for 17.5 per cent and moisture amount of 81.1 per cent. Chili sauce which is added with water melon peel for 9 per cent has total energy for 71.2 per cent; protein is less than 1.25 per cent fat is 0 per cent ash is 3.85 per cent; carbohydrate is 17.8 per cent and it has moisture amount of 78.4 per cent. Pizza sauce which is addedwith water melon peel for 30 per cent has total energy for 145 per cent; protein is less than 1.25 per cent fat is 3.49 per cent ash is 3.18 per cent; carbohydrate is 28.5 per cent and it has moisture amount of 64.8 per cent. Seafood sauce which is added with water melon peel for 20 per cent hashas total energy for 91.8 per cent; protein is 1.59 per cent fat is 0.20 per cent ash is 4.19 per cent; carbohydrate is 20.9 per cent and it has moisture amount of 73.1 per cent. However adding of water melon peel into four kinds of sauce products can be done but it should be realized about chemical components of starting components for example moisture amount and carbohydrate. These components may affect physical features for example smell flavor and texture. These features affect acceptance of products. From technology transfer of sauce products from water melon rind at 157/16 moo 9 Kao San housewife Group agricultural enterprise Bang Plee Bang Pla Samut Prakarn. 50 housewife Group agricultural there the level of satisfaction in every aspect.
