For the first time, major proteins from sorghum distillers grains were individually extracted and transformed into high-quality protein films via an aqueous system. Sorghum distillers grains are by-products of bioethanol production from sorghum grain. However, extracting sorghum proteins from distillers grains poses challenges due to protein densification and denaturation during ethanol production's distillation and drying phases. The increased non-covalent interactions among protein molecules further complicate their extraction. Moreover, previously, only the kafirin part, accounting for 55 % of sorghum proteins, was extracted while the glutelin, which has a higher molecular weight than kafirin and accounts for about 35 % of sorghum proteins, was left in distillers grains. Kafirin and glutelin from sorghum distillers grains were successfully extracted with a high yield in this work. The extraction technology individually separated kafirin and glutelin from sorghum distillers grains, providing a high extraction yield of up to 83 % and protein purity of 93 %. Besides, more kafirin subunits rich in cysteine were obtained by incorporating the oxidation step. An aqueous system was also developed to regenerate proteins and fully stretch both kafirin and glutelin simultaneously, improving interactions between protein molecules, enhancing molecular entanglement, and inducing ordered protein structures. As a result of protein extraction and dissolution techniques, tough and flexible protein films were developed from sorghum distillers grains.</div></div>","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"222 ","pages":"Article 120046"},"PeriodicalIF":5.6,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142654111","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, in this study, we prepared the coating by a simple one-pot sol-gel method, modified silicate (water glass) by introducing green non-toxic organic polymer with sodium silicate solution (water glass) as the base material, and used polyvinyl alcohol (PVA) and aminopropyl double-ended polydimethylsiloxane (2NH₂-PDMS) as the modifier. Triton X-100 as dispersant and ethyl acetate as curing agent were used to prepare three-dimensional crosslinked network structure (C-O-Si-OH-NH₂) sodium silicate composite coating. When exposed to flame, the non-combustible carbon layer formed by the three-dimensional network crosslinked structural coating can act as a strong fire barrier for the substrate, and the flame-retardant performance is far better than other coatings.

Frequent frosts in early spring often result in reduction or complete loss of apricot blossoms, fruits and seeds. Therefore, breeding late flowering varieties of the apricot is one of the important strategies to avoid frost damage. However, the mechanism regulating flowering time remains largely unknown in this species. Here, the transcriptomes of the apricot cultivars Weixuan No.1 (<em>Prunus armeniaca</em> L., late flowering) and Shanxing (<em>Prunus sibirica</em> L., early flowering) were analyzed to identify the genes regulating flowering time. The pairwise comparison identified 4900 genes with differential expression between cultivars.
