“…The gel microstructure largely determines the performance of the gel, but KGM gels prepared through different methods are significantly different in terms of microstructure [ 19 , 20 , 21 ]. With good biocompatibility and biodegradability [ 22 , 23 , 24 ], KGM gels have been widely used in food [ 19 , 21 , 25 ], pharmaceutical carriers [ 14 , 26 ], tissue scaffolds [ 27 , 28 ], absorbing materials [ 2 , 29 ] and other fields. In this study, different KGM gel preparation methods and the gel microstructures were reviewed.…”

Konjac glucomannan (KGM) has attracted extensive attention because of its biodegradable, non-toxic, harmless, and biocompatible features. Its gelation performance is one of its most significant characteristics and enables wide applications of KGM gels in food, chemical, pharmaceutical, materials, and other fields. Herein, different preparation methods of KGM gels and their microstructures were reviewed. In addition, KGM applications have been theoretically modeled for future uses.

Background: The Yi is the largest ethnic group in Yunnan Province (China), with a population of five millions. The Yi people tend to live in mountainous areas, and their culture includes a unique dietary system for treating and protecting people against illnesses. Medicinal plants occupy an essential place in the Yi diet because they play a key role in health and the prevention and treatment of diseases. However, few studies have addressed these medicinal dietary plants and their importance in the Yi’s daily lives. The aim of this study was to (1) investigate the medicinal dietary plants used by the Yi in Mile City, (2) document the traditional knowledge held about these plants, (3) identify species with important cultural significance to the Yi in Mile City, and (4) analyze the special preparation methods and consumption habits of these plants. Methods: Field investigations were performed in six villages in Mile City, Honghe Hani and Yi Autonomous Prefecture, Yunnan, from July 2017 to May 2018. Information was collected using direct observation, semi -structured interviews, key informant interviews, individual discussions and focus group discussions. The use -value (UV) and frequency of utilization index (FUI) of these plants were analyzed. Plant samples and voucher specimens were collected for taxonomic identification.Results: This study documented 124 species belonging to 62 families and 102 genera. These plants included: angiosperms (117 spp.), gymnosperms (3), pteridophytes (2), lichens (1), and fungi (1). The 20 species with the highest UV were noted as being particularly important to the Yi people’s daily life in Mile City. The primary medicinal preparation method for plants recorded in the study was decoction. The most commonly used plant parts were fruits and roots. The most frequently used edible parts were fruits, and the most frequently used medicinal parts were roots. The medicinal parts were used to treat diseases such as rheumatism, oedemas, kidney deficiency, spleen deficiency, gastritis, parasites and so on. Conclusion: A wide variety of medicinal dietary plants are used by the Yi people in Mile City. Those plants, which have both rich nutritional and medicinal value, occupy an essential part of the Yi dietary and medicine culture. Ethnobotanical surveys of medicinal dietary plants provide a theoretical reference for the conservation and sustainable use of the plant resources and could contribute to the protection of the Yi food culture and traditional medicine in Mile City. In addition, this information provides a sound basis for developing and using Yi ethnic medicine and health products.

“…Medicinal dietary plants, because of their excellent beneficial effects in disease prevention and treatment, should be developed as health products or drugs [44]. The bulb of A. konjac is used to remove toxicity, to treat detumescence, to invigorate the stomach and to stop pain; in addition, it can treat bronchitis and persistent cough [45]. The bulb of this herb has glucomannan, flying powder, starch, proteins, amino acids, and impurities.…”

Background With a population of more than 5 million, Yi is the largest of the 25 ethnic groups in Yunnan Province, China. Yi people tend to live in mountainous areas, and their culture includes a unique dietary system for treating illnesses and protecting people against them. Medicinal plants occupy an essential place in the Yi diet because they play a key role in health and the prevention and treatment of diseases. The objectives of this paper were to document the medicinal dietary plants and the traditional knowledge associated with them and describes this paper adequately. Methods Field investigations were carried out in six villages in Mile County, Honghe Hani and Yi Autonomous Prefecture, Yunnan, from July 2017 to May 2018. Information was collected using participatory rural appraisal (PRA), direct observation, semi-structured interviews, key informant interviews, individual discussions, focus group discussions, and questionnaires. Results The study documented 124 species belonging to 62 families and 102 genera. These included: angiosperms (117 spp.), gymnosperms (3), pteridophytes (2), lichens (1), and fungi (1). The most commonly used plant parts were fruits and roots. The most frequently used edible parts were fruits, and the most frequently used medicinal parts were roots. The medicinal parts were used to treat conditions such as cough, catarrh, rheumatism, swelling, kidney deficiency, spleen deficiency, gastric disease, and others. Some of the plants required special preparation. Several had good economic potential due to their significant effects. In addition, a number of these plants are scarce and require conservation. The use-value (UV) and frequency of utilization index (FUI) of medicinal dietary plant species were analyzed. The 20 species with the highest UV were noted as particularly important to the Yi people’s daily life in Mile county. Conclusion A wide variety of medicinal dietary plants is used by Yi people in Mile. These plants occupy an essential position in the Yi diet and medicine. These plants are not only nutritious but also have medicinal value and, by consuming them, the Yi people maintain health and treat diseases through their daily diet. Ethnobotanical surveys of medicinal dietary plants provide a theoretical reference for the conservation and sustainable use of these plant resources and can contribute to the protection of the Yi food culture and traditional medicine in Mile. In addition, this information provides a basis for the development and utilization of Yi ethnic medicine and health products.
