Abstract

To investigate the effects of ultra-high pressure (UHP) treatment and vegetable oil addition on its heat-induced gel properties, rabbit myosin was subjected to UHP treatments (10 ℃/2 min) at different pressure levels (100, 150 and 200 MPa), and then mixed with different amounts (0%, 10%, 20% and 30%) of soybean oil and phosphate buffer to prepare emulsion systems, whose heat-induced gelation was carried out at a programmed heating rate of 1 ℃/min. Myosin not treated by UHP served as control. The storage modulus G’, loss modulus G”, gel strength, water-holding capacity (WHC), microstructure and relaxation time spectra of heat-induced myosin gels were measured by rheometer, texture analyzer, scanning electron microscope (SEM) and low-field nuclear magnetic resonance spectroscopy (NMR). The results showed that compared with the control group, the storage modulus, loss modulus, gel strength and WHC of heat-induced myosin gels were increased significantly by high pressure treatment and the addition of soybean oil. SEM revealed that the three-dimensional network structure became denser and more compact. The NMR analysis showed that the relative content of free water in the gel matrix gradually decreased with an increase in pressure, and the degree of proton binding of immobilized water and the relative content of bound water significantly increased. Under the same pressure, the G’, G”, gel strength and WHC increased with increasing addition of soybean oil, showing significant differences among addition levels (P < 0.05). The 200 MPa + 30% soybean oil group had the best heat-induced gel properties. Therefore, appropriate high-pressure treatment combined with the addition of soybean oil enhanced the interaction between protein and fat, and changed the microstructure and water distribution state and consequently gel properties such as rheological properties, texture and WHC of heat-induced myosin gels, which played a positive role in improving the functional properties of heat-induced rabbit myosin gels.

Abstract

As the use of triboelectric nanogenerators (TENGs) increases, the generation of related electronic waste has been a major challenge. Therefore, the development of environmentally friendly, biodegradable, and low-cost TENGs must be prioritized. Having discovered that plant proteins, by-products of grain processing, possess excellent triboelectric properties, we explore these properties by evaluating the protein structure. The proteins are recycled to fabricate triboelectric layers, and the triboelectric series according to electrical properties is determined for the first time. Using a special structure design, we construct a plant-protein-enabled biodegradable TENG by integrating a polylactic acid film, which is used as a new type of mulch film to construct a growth-promoting system that generates space electric fields for agriculture. Thus, from the plant protein to the crop, a sustainable recycling loop is implemented. Using bean seedlings as a model to confirm the feasibility of the mulch film, we further use it in the cultivation of greenhouse vegetables. Experimental results demonstrate the applicability of the proposed plant-protein-enabled biodegradable TENG in sustainable agriculture.

Abstract

Organic amendment is an effective method to reclaim salt-affected soil. However, in coastal land with shallow saline groundwater, it is limited known about the mechanism of organic amendment on soil desalinization. Thus, to examine the effect of topsoil organic matter content on soil water/salt transport and distribution, two-year field observations in Bohai coastal land, North China, and soil column experiments simulating salt accumulation and salt leaching were conducted, respectively. There were different organic fertilizer amendment rates in 0–20 cm topsoil, 0% (CK), 50% (OA 0.5), and 100% (OA 1.0) (w/w) for soil column experiments. Field observation showed that after organic amendment (OA), the soil's physical structure was improved, and less of the increase in topsoil salt content was observed, with more salt accumulated in deep soil layers during the dry season. In addition, OA greatly promoted salt leaching during the rainy seasons. The results of the soil column tests further indicated that OA treatments significantly inhibited soil evaporation, with less salt accumulated in the topsoil. Although there was no difference in soil water distribution between the CK and OA 0.5 treatment, the topsoil EC for the OA 0.5 treatment was significantly lower than that for CK. During soil water infiltration, the OA 0.5 and OA 1.0 treatments significantly increased the infiltration rates, enhanced the wetting front, and promoted salt leaching to deeper soil layers, compared with CK. The improvement of soil organic amounts could make the soil more self-resistant to the coastal salinization. The findings of this study provide some insights into soil water/salt regulation in heterogeneous soil masses and on the permanent management of coastal saline farmland. [ABSTRACT FROM AUTHOR]
