“…In addition, since PVA is a water soluble polymer, it is also widely used in the creation of biodegradable packaging. Plasticizers, such as glycerol, are added for increased flexibility and reduced brittleness, whereas surfactants, such as tween 20, are added to enhance the plasticizer function [23]. Together with reagents such as chitosan, cellulose, and cross linking reagents, a biodegradable film which is highly dissolvable in water is created [24,25,26,27,28,29,30].…”

Integrating a dissolvable membrane into a sensor allows the control of sample flow, location and duration in critical areas. These time-barrier films stop the flow of samples until the membrane has dissolved, thus, for example, allowing increased exposure time between immunoreagents for the formation of greater numbers of immuno-complexes, ensuring higher sensitivity, reactivity, and helping to reduce false-positive signals. In this study, dissolvable polyvinyl alcohol (PVA) films are used in a 3D-printed sensor holder, which enables film integration without the use of glue. PVA is a synthetic hydrophilic linear polymer, its solubility is dependent on its molecular weight and degree of hydrolysis. Three types of PVAs films were tested herein: (1) PVA 1-Mw: 30–70 K, 87–90% hydrolyzed; (2) PVA 2-Mw: 31–50 K, 98–99% hydrolyzed and (3) PVA 3-Mw: 89–98 K, >99% hydrolyzed. The films were exposed to water in (1) the novel 3D-printed holder and (2) directly immersed into a water droplet. After comparing the time taken to dissolve PVA 1–3 films, PVA 1 films of 5–20% (w/v) are found to be most suitable as time barrier films, due to their optimal dissolution times and physical properties for integration into the customized 3D-printed holder.

“…Taking into consideration the biodegradability of starch [ 3 ], for many years, one can observe numerous attempts to modify starch of various botanical origins in order to widen the range of use of this material, as well as to change its properties. In the textile industry, starch is used as a binding material in the production of corrugated cardboard [ 4 , 5 ].…”

The Process of Pasting and Gelling Modified Potato Starch with LF-NMR

et al. 2022

Currently, society expects convenience food, which is healthy, safe, and easy to prepare and eat in all conditions. On account of the increasing popularity of modified potato starch in food industry and its increasing scope of use, this study focused on improving the physical modification of native starch with temperature changes. As a result, it was found that the suggested method of starch modification with the use of microwave power of 150 W/h had an impact on the change in starch granules. The LF-NMR method determined the whole range of temperatures in which the creation of a starch polymer network occurs. Therefore, the applied LF-NMR technique is a highly promising, noninvasive physical method, which allows obtaining a better-quality structure of potato starch gels.
