“…Due to its easy cultivation and production of starch-rich roots, cassava is emerging as the most important tropical tuber crop (Krishnakumar et al, 2020;Pushpalatha and Gangadharan, 2020). According to the Food and Agriculture Organization of the United Nations, "cassava is very important in feeding half a billion people in the world" (Boukhers et al, 2022;Abotbina et al, 2022;Da Silva Pereira et al, 2021;Fathima et al, 2022). Brazil is the third-largest cassava producer in the world (FAO, 2020; , with the State of Pará as the largest national producer.…”

Cassava (Manihot esculenta Crantz), is a staple crop widely cultivated by small farmers in developing countries. However, despite the low required level of technology required for its management, it can be affected by several diseases, with anthracnose as the main threat. There is little information about the main species of Colletotrichum that infect cassava in Brazil. Thus, the objective of this work was to study the diversity, prevalence and virulence of Colletotrichum species that cause anthracnose in cassava leaves in northern Brazil. Twenty municipalities of Pará and Tocantins states were selected and leaves with symptoms were collected in those locations. Pure cultures were isolated in the laboratory. Species were identified using phylogenetic analyses of multiple loci and their pathogenicity, aggressivity and virulence levels were assessed. Our results found a greatest diversity of Colletotrichum associated with anthracnose in cassava plants of the “Formosa” cultivar on Tocantins and Pará states. We determined the presence of Colletotrichum chrysophilum, C. truncatum, C. siamense, C. fructicola, C. plurivorum, C. musicola and C. karsti; with C. chrysophilum as the most aggressive and virulent. Our findings provide accurate identifications of species of Colletotrichum causing anthracnose in cassava crops and provide important information for a more effective control of this disease and the adoption of anthracnose management strategies. These include the development of cultivars with resistance genes to the different pathotypes prevalent in the areas of cultivation, which will potentially reduce production costs.

“…Nowadays, the problems of petroleum resources depletion and environmental pollution intensifying which was caused by heavily used plastic packaging, are more and more serious. [ 1 ] With the rapid development of society and the enhancement of people's environmental awareness, the bio‐based degradable films for packaging applications exhibited huge possibilities for reducing the usage of traditional plastic packaging. As the result, as the abundant and renewable resources in nature, some proteins, starches or complex of them are considered as the basic biodegradable materials for packaging, have attracted special attention on the synthetic polymers substitute.…”

In order to evaluate the stability of soybean isolate protein (SPI)-corn starch (CS) composite films, physical properties and application in packaging of the SPI-based composite films are observed during storage. Results show that mechanical property changed more obvious (increased TS and descended EB) with increase of storage temperature from 5 to 35 °C and increased CS content in the SPI-CS composite films is not in advantage of mechanical property improvement. Furthermore, combined with results of light transmittance, oil barrier property, and water solubility, it is obtained that low temperature (≤20 °C) is preferred for storage of SPI-based composite films, and SPI:CS (4:1) composite film shows best performance during the whole storage. Finally, films applied in packaging result indicate the SPI:CS (4:1) composite film can be selected as seasoning inner packaging at low temperature.

Biodegradable films are considered an alternative to petroleum‐based plastics to solve environmental problems. In this study, potato flour films are prepared with dispersions at pH 3, 5, 7, 9, and 11. The film‐forming dispersion at pH 7 shows the highest apparent viscosity. Dispersions at alkaline conditions show a reduction in particle size, resulting in a smooth film surface. Films at alkaline conditions present a yellow appearance and have the lower transmittance. The film at pH 5 has the highest retrogradation enthalpy and glass transition temperature, while its moisture content and solubility are the lowest. The water contact angle increases from 33.33° to 93.67° with the increase in pH. However, pH has no significant effect on the water vapor permeability. The tensile strength and elongation at break increase slightly with the increase in pH. Overall, pH modifies the properties of potato flour films. Film with appropriate performance can be selected based on actual needs, such as the use of packaging materials for food preservation.
