original: Wei Shiping Eating today is not ignorant today
When cooking porridge as a child, the father of the medical sect always reminded me not to forget to put some yams, and said, "yams are the ginseng of the common people, which can both nourish and not get angry." But the reason why the childish looking granny eater frowned and even sometimes was lazy was that the peeling process was too painful, and it would make the back of her hand itch for a long time if it was not well done.
It's the smooth taste of yam in the porridge. With the childhood memories of my mother-in-law, we have gone through decades... It would be perfect if we could taste the taste of yam without peeling. Like a magic wand in a fairy tale, on July 10, at the "Iron Stick Yam Powder Expert Evaluation Meeting" in Beijing, the imagined delicacy and perfection brightened the eyes of the mother-in-law. The smell of yam filled the meeting place. The Chinese Food Science and Technology Society organized experts to identify the key technology of Tieguoshan powder production jointly developed by Henan Jinghua Food Science and Technology Development Co., Ltd. and Beijing Technology and Business University.
Who are there? Meng Suhe, President of the Chinese Food Science and Technology Society, Sun Baoguo, Academician of the Chinese Academy of Engineering, Hu Xiaosong, Dean of the School of Food Science and Nutrition Engineering of China Agricultural University, Ma Guansheng, Professor of the Department of Nutrition and Food Hygiene of the School of Public Health of Peking University, Chen Zhenjie, Chief Engineer of the Henan Provincial Commission of Industry and Information Technology, and nearly 20 experts from the scientific and industrial circles. It's really a strong team of experts! http://s11/mw690/002XHXf2zy7m0zWrxTs5a&690
Can Chinese yam powder still taste like fresh Chinese yam?
It's not "dried yam" It uses fresh yam as raw material, and combines biotechnology and new spray drying technology. In the process, it broke through the technical barrier that the viscosity of raw yam pulp is too high for spray drying, and improved the solubility of Tiebang yam powder. The overall technology is at the international advanced level. It effectively retains the original flavor, nutrition and functional ingredients of Tieguoshan, which are fresh, fragrant and sweet, and enhances the flavor characteristics of Tieguoshan powder. And it is convenient to eat. You can drink it with warm boiled water.
In this regard, Meng Suhe, president of the board of directors, said that the fact that Henan Jinghua Food Science and Technology Development Co., Ltd. and Beijing Technology and Business University jointly developed Tiebang yam powder shows that the tide of healthy transformation of the food industry with traditional diet culture as its source has come. The scientific research team led by Academician Sun Baoguo has deeply cooperated with enterprises in R&D and preparation. This docking of technology and industry has formed momentum to change the face of the industry. Without deep integration with technology, it is difficult for enterprises to have sustainable and long-term development. Depending on the enterprise's own efforts, sometimes it will encounter many difficult problems. The whole body of yam is treasure, but how to extract and improve its essence? It needs the support of scientific force.
How did the academician team like "yam"?
Generally speaking, Academician Sun Baoguo is busy with his own major besides serving as President of Beijing Technology and Business University. Why do you care about the technicalization of "yam"?
It starts from Wen County, Henan Province, which is a nationally famous "hometown of medicine". According to the records in the county annals of Wen County, "it won the gold medal at the Panama World Expo in 1914 and became famous at home and abroad. In 1962, the country selected it as the" treasure of national medicine "from 1892 kinds of Chinese medicinal materials, and in 2003, it was listed as a national origin protection product.". In 2012, the government successfully registered the registered trademark of "Wenxian Tiebang Yam", and realized the traceability of product quality through regulating the market, standardized planting, GPS positioning, and two-dimensional code identification. Since then, Wenxian Tiebang Yam has its own identity card. Wenxian County has 460000 mu of arable land, and the perennial area of Huaiyao is about 100000 mu. In particular, Wenxian Tiebang yam, with its unique quality and unique efficacy, has become a business card of Wenxian County's characteristic industry, and is listed as one of the three characteristic gifts in Henan Province along with Haoxiangyou and Xinyang Maojian.
Academician Sun Baoguo concluded that good soil and good resources have produced good yams. It should not only be enjoyed by Chinese people, but also be sold abroad for everyone to share. This requires the help of high-tech forces to make it more perfect.
Wang Jing, a professor from the School of Food, Beijing Technology and Business University, said in the evaluation report that there are four major technical innovations in the Tieguoshan Yam Powder series. First, the strict selection of raw materials has realized the monitoring of the whole supply chain "from field to table". The unique fresh Tieguan yam in Wenxian County was selected as the raw material. The two-dimensional code scanning and GPS positioning technology were used in the planting process of raw materials, which greatly improved the nutrition and safety quality of the product. Second, the "original flavor" of Tiebang yam is retained by using bioengineering technology, which completely retains the fresh, fragrant, sweet and other characteristics of Tiebang yam, so that consumers can enjoy the seasonal taste of the original flavor throughout the year. Third, due to the high viscosity of yam, when using ordinary spray drying technology for drying, problems such as blocking and serious wall hanging are easy to occur. Therefore, a new spray drying technology has been developed for the physical properties of raw materials of yam, overcoming the technical barrier of "Tiebang yam has high viscosity and is not suitable for spray drying". Fourthly, the development of soluble and non precipitated instant powder of Tiebang yam has enriched the domestic market of instant powder of yam. Through the selection of raw materials and the optimization of the whole process, the "original flavor" and active ingredients of fresh Tieguan yam are largely retained, and can be easily dissolved and not precipitated, significantly improving the preparation performance of the product, and comprehensively improving the product quality of yam powder in the domestic market.
Is yam really "common people ginseng"?
Yam, the Dioscoreaceae, is also food and medicine. There are Mianshan Yam and Crisp Yam. Huaishan Medicines belong to Mianshan Medicines, which have the same origin in medicine and food. It is named after Gu Huaiqing (Jiaozuo District) and is one of the four famous Huaishan Medicines in the world. Wang Suxia, a researcher of agricultural technology extension, said. It has been planted and processed locally for 3000 years. In ancient times, it was listed as royal tribute, collected every year, and spread to all parts of the world through the "Silk Road" and "Zheng He fleet", enjoying the reputation of "Chinese medicine". Traditional Chinese medicinal materials pay attention to the "authentic" nature, and different origins of the same plant lead to different medicinal properties. According to the Compendium of Materia Medica, "yams can nourish deficiency and win, eliminate cold and heat evils, nourish the middle and strengthen qi, build muscles, strengthen yin, and make ears and eyes bright after taking a long time. The body is light but not hungry, and prolong life." According to the Meng Quan of Materia Medica, "yams are produced in both northern and southern prefectures, but those who celebrate are good"; "Shennong's Classic of Materia Medica" records: "yams are good when they are celebrated in Henan"; It is recorded in Chinese Pharmacology that "yams in Wenxian County have been both the main producing area and the important processing place since ancient times, and are famous both at home and abroad". The ancient books and records of traditional Chinese medicine and the historical records of famous doctors in the past dynasties all gave high praise to Huaishan medicine.
Chinese yam is rich in saponins, mucilage, choline, arginine, etc. It has the effects of strengthening the spleen and tonifying deficiency, nourishing yin and strengthening the kidney, treating all kinds of deficiency and damage, treating the seven injuries of five tuberculosis, supplementing qi, generating muscle, and strengthening yin. It is a model of "homology of medicine and food", and has huge market potential at home and abroad. The original ecological nourishing products will be the direction and mainstream trend of future health products, known as the gold industry in the 21st century. The fresh Tieguan yam powder is rich in protein, various amino acids and trace elements, and its market prospect is very optimistic.
Finally, the experts suggested that the industrialization development should be further strengthened to meet the needs of the elderly, children, fitness groups and other different consumers.
