“…In rice and corn starch-based TPS, glycerol is used as plasticizer, due to its better mechanical properties and good water solubility, ranging from 18 to 25%, though it can increase up to 36% [33,41]. It was shown that the glycerol concentration would not affect the glass transition temperatures.…”

“…They further investigated the phase separation mechanisms and their consequence on the size of starch granules during the drying process and the frictional, thermal, mechanical, thermal, optical, and water-barrier properties. Gómez-Heincke et al [33] manufactured bioplastics from the proteins derived from potato and rice. Glycerol with different concentrations was mixed with the proteins.…”

Due to the negative environmental impacts of synthetic plastics, the development of biodegradable plastics for both industrial and commercial applications is essential today. Researchers have developed various starch-based composites for different applications. The present work investigates the corn and rice starch-based bioplastics for packaging applications. Various samples of bioplastics are produced, with different compositions of corn and rice starch, glycerol, citric acid, and gelatin. The tensile properties were improved after adding rice starch. However, water absorption and water solubility were reduced. On the basis of these results, the best sample was analyzed for thickness testing, biodegradability properties, SEM, hydrophilicity, thermogravimetric analysis, and sealing properties of bioplastic. The results show the suitability of rice and corn-based thermoplastic starch for packaging applications.

“…It was proven that potato protein bioplastic is not affected by glycerol concentration, thermosetting for moulding, it has complex modulus value close to the one for low density polyethylene and it has resistance to higher temperatures, when compared with wheat and rice bioplastics. This plastic also showed low water absorption values (9 %), compared to wheat protein plastic, due to patatin content [31]- [33].…”

“…Potato protein bioplastics are yet to be studied extensively. In the work of Gomez-Heincke, et al [31] rice and potato proteins were studied as a source for bioplastics, making them in a mix with glycerol as plasticizer and wheat proteins as a reference material. It was proven that potato protein bioplastic is not affected by glycerol concentration, thermosetting for moulding, it has complex modulus value close to the one for low density polyethylene and it has resistance to higher temperatures, when compared with wheat and rice bioplastics.…”

-The increasing amount of food waste througout the world is becoming a major problem for waste management plants. The food waste produced amounts to 1.3 million tons a year. This is a resource that could be used for production of new products. Decreasing fossil resources and a rapidly growing population lead to the necessity to produce more food and to replace existing with new materials ones that are biological and produce little effect on environment. Bioeconomy is a method that can help achieve production of value-added products that use local resources and waste to manufacture products efficiently. In this article, we are looking at possibilities to use potatoes for production of new materials, such as bioplastics, antioxidants, proteins, instead of their conventional use for food production. We have studied potato components, extraction technologies and summed up possible directions for development for new products, looking at the use of processing waste as a raw material.

“…c) for the properties already mentioned and because the protease inhibitors present in the potato have an appetite suppressant effect (Matharu et al , ). In addition, these proteins can also be used for the production of bioplastics by mixing with a plasticiser (Gómez‐Heincke et al , ). On the other hand, the possibilities of obtaining added‐value products increase with the possibility of hydrolyse the proteins into amino acids [lysine, leucine, histidine and valine are those that are found in greater quantity not only in the free form, but also being part of proteins from Group Phureja according to Bártová et al ()].…”

Summary Potato tubers of Group Phureja have a great relevance in terms of production and consumer acceptance in the Andean countries. However, its proximal characteristics, nutritional value and bioactive compounds have been scarcely known. For the first time, this work aims to give an overview on tubers of Group Phureja characteristics, including research works from 1993 to 2019. When analysing the micronutrients and bioactive analytes, sodium, niacin and carotenoid contents are higher as compared to those of the Group Tuberosum. Likewise, the application of a biorefinery approach for the valorisation of Group Phureja wastes was proposed. These wastes may come from tubers that fail to meet quality parameters or by processing potato products. The possibility of obtaining useful compounds for the food, feed, materials, energy and chemical industries is described. The strategy of valorisation of wastes was focused on the production of starch and proteins, previously reported with important technological properties.
