Although made from the same, refined products from soybeans having different nutritional content. Lecturer at the Department of Food Science and Technology, Faculty of Agricultural Technology, Bogor Agricultural University, Sugiyono, say, to determine the nutritional value of a food should be measured by levels of specific content, such as protein content, fat content, the levels of certain vitamins, fiber content, etc. other. Nutritional value of a food should also be associated with the goal of eating it. For people who are dieting, low fat diet is better than a diet high in fat content. Conversely, for a lack of energy is better to eat a diet high in fat. Products made from soybeans, according to Sugiyono, generally have relatively high levels of protein. Know basically composed of protein and water so that the high levels of protein. Meanwhile, soybean protein contains not only high, but it also contains fat, vitamins, minerals, and has good digestibility. Ketchup and soy milk contains proteins and fats that are not too high (levels of protein and fat content of less than 5 percent). Tauco contain soy protein and fat. Curd contain proteins and fats are relatively high. Overall, according to Sugiyono, among the above products, tempeh has a protein content, fat content, mineral content, vitamin content, fiber content and high digestibility.

Antigizi substances at levels too low tempe. The lower anti-nutritional substances, then the better the nutritional content in a food. Storage of soy products have different durability as well as it is stored. Tofu should be kept in the refrigerator and can hold for a few days. At room temperature, can hold out only a half day or one day. “If you know it can hold more than one day at room temperature, most likely knows that already given a preservative,” said Sugiyono. Soy milk does not last long. For that soy milk should be stored in the refrigerator after being purchased or made, except for soy milk products that have been sterilized in the package. The Tempe, oncom, and tempeh gembus can hold it for one or two days at room temperature. Tempe should be stored in the refrigerator so it can hold for a few days. Ketchup and durable tauco at room temperature. If tauco already opened the packaging should be stored in the refrigerator. Curd, baby food, snacks, and mock meats can also be stored at room temperature for dry and durable. Similarly, the soybean oil.
