Crude Fiber (CF), an old name for Crude Fiber, is a major constituent of plant cell walls, including cellulose, hemicellulose, lignin, cutin, and the like. Eating food containing crude fiber can promote gastrointestinal movement, can help digestion to a certain extent, and is beneficial, but the crude fiber can also prevent digestive enzymes in the digestive tract from contacting with chyme so as to reduce the digestibility of nutrients, and in addition, the crude fiber can also prevent the intestinal tract from absorbing some small molecular nutrient substances.
The main consumer groups of crude fiber foods are adults and the elderly, who suffer from obesity, hyperlipidemia, diabetes, due to work, life tension and physiological reasons. However, when people eat the coarse fiber, the recommended intake of the coarse fiber in the nutriology is 20-35 g per person per day, and the utilization rate of other nutrients is reduced when people eat more coarse fiber.
When the content of crude fiber in food is measured, acid washing and alkali washing are needed to be carried out to enable the crude fiber to be washed to be neutral, generally, 1.25% sulfuric acid is used for washing off sugar, starch, pectin and hemicellulose in a sample, 1.25% alkali is used for treating the sample to remove protein and fatty acid, the residual residue is crude fiber, and whether the washing reaches the neutral state has certain influence on the accuracy of detecting the crude fiber in the food.
Therefore, for the food pattern subjected to acid and alkali treatment, the food pattern needs to be repeatedly washed by pure water to be neutral, meanwhile, sugar, starch, pectin, hemicellulose, protein and fatty acid in the pattern need to be repeatedly twisted and washed by hands, and the residual residue is crude fiber, such as impurity which is insoluble in acid and alkali and can be removed after ashing.
