Which has a higher oil content, soybean or sugar beet? The answer is soybean.
The oil content of soybean is higher than that of sugar beet. The main purpose of soybean is oil extraction, and it is the world's most important provider of edible vegetable oil and protein meal. The main purpose of sugar beet is sugar extraction; the filter mud left after sugar production is rich in calcium and other nutrients, and can be used as fertilizer while also helping to neutralize free acids in the soil.
1. Soybean oil yield
The oil yield of soybean is actually not high. Even with the highest-quality soybeans and the most advanced oil press, the oil yield of soybean is only 14%. However, what creates value in soybean oil extraction is not only the soybean oil; the soybean meal produced by oil extraction also has high utilization value. The residual oil rate in soybean meal is about 6%, and it also contains crude protein, amino acids, lysine and other elements. It can be sold to food processing companies to make foods such as tofu skin and dried tofu, and can also be sold to biopharmaceutical companies to make medicines.
2. Main value of sugar beet
Sugar beet is an important cash crop and one of China's main sugar crops. Besides being used for sugar production, its by-products also have high comprehensive utilization value. For example, molasses can, through fermentation or chemical treatment, be used to produce methanol, ethanol, butanol, glycerin, monosodium glutamate and acetone, among others. Sugar beet stems and leaves, green tops, tail roots and sugar beet pulp can be used as brewing raw materials to extract betaine, among other things, and are also high-quality succulent feed.
