Problems solved by technology

[0002] Bamboo shoots are rich in protein, amino acids, fats, sugars, calcium, phosphorus, iron, carotene, vitamins B1, B2, and C. The content of multivitamins and carotene is more than double that of Chinese cabbage; moreover, the protein content of bamboo shoots Relatively superior, the human body needs laurine, tryptophan, threonine, phenylalanine, as well as glutamic acid which plays an important role in the process of protein metabolism and cystine which maintains the protein configuration. A certain content is an excellent health-care vegetable. Bamboo shoots are also low in fat, low in sugar, and multi-fiber. The use of bamboo shoots can not only promote intestinal peristalsis, help digestion, remove food accumulation, prevent constipation, and prevent colorectal cancer. Bamboo shoots Containing very little fat and starch, it is a natural low-fat and low-calorie food, which is a good product for obese people to lose weight. The dehydration treatment of bamboo shoots can effectively improve the shelf life of bamboo shoots. A large amount of internal nutrients are lost, accompanied by partial protein denaturation, which greatly reduces the nutritional value of bamboo shoots
