“…Because of the extremely strong interlayer forces in BM, the key to the successful exfoliation of BM NSs is to decrease the cohesion energy and open up the crystallite of BM . As K + is firmly locked in the interlayers of BM to counterweigh the charge due to the severe charge deficiency of BM layers, calcination at 800 °C was used to decrease the attraction force between the layers and K + . In the past decade, lots of previous studies have tried to weaken the interlayer attraction force and increase the interlayer spacing of mica .…”

“…For example, due to the small size and positive charge of Li + , Li + was used to extract K + from the interlayers . Then, long‐chain positive ion polymers, such as the octadecyl trimethyl ammonium ion or hexadecyl trimethyl ammonium bromide, were employed to intercalate into the interlayers of mica to further expand the interlayer spacing 6a,10,11. In this study, n ‐butyllithium with a Li + head and relatively long‐chain tail was chosen to achieve K + extraction and interlayer spacing expansion in a single step.…”

Synthesis of Ultrathin Biotite Nanosheets as an Intelligent Theranostic Platform for Combination Cancer Therapy

Biotite, also called black mica (BM), is a group of sheet silicate minerals with great potential in various fields. However, synthesis of high‐quality BM nanosheets (NSs) remains a huge challenge. Here, an exfoliation approach is provided that combines calcination, n‐butyllithium exchange and intercalation, and liquid exfoliating processes for the high‐yield synthesis of ultrathin BM NSs. Due to the presence of MgO, Fe2O3, and FeO in these NSs, PEGylated BM can be engineered as an intelligent theranostic platform with the following unique features: i) Fe3+ can damage the tumor microenvironment (TME) through glutathione consumption and O2 production; ii) Generated O2 can be further catalyzed by MgO with oxygen vacancy to generate ·O2−; iii) The Fe2+‐catalyzed Fenton reaction can produce ·OH by disproportionation reactions of H2O2 in the TME; iv) Reactions in (i) and (iii) circularly regenerate Fe2+ and Fe3+ for continuous consumption of glutathione and H2O2 and constant production of ·OH and O2; v) The NSs can be triggered by a 650 nm laser to generate ·O2− from O2 as well as by an 808 nm laser to generate local hyperthermia; and vi) The fluorescent, photoacoustic, and photothermal imaging capabilities of the engineered NSs allow for multimodal imaging‐guided breast cancer treatment.

“…Studies have also been conducted on the fractionation of specific components of okara, such as dietary fibres, proteins and isoflavones [96,[192][193][194][195][196]. This contributes both to the biovalorisation of these isolated components and to higher efficiency and yield than the direct fermentation of okara.…”

Valorisation of By-Products from Soybean (Glycine max (L.) Merr.) Processing

et al. 2020

In recent years, increased awareness of the health benefits associated with consuming soy-based foods, knowledge of milk-related allergies and a move towards more sustainable food production have led to an increase in the number of available soy-based products. The biggest producers in the world, the USA, South America and China, are from the Pacific region. This enormous production is accompanied by the accumulation of related by-products, in particular, a substance that is known as okara. Okara is a paste that is rich in fibre (50%), protein (25%), fat (10%), vitamins and trace elements. Its proper use would lead to economic advantages and a reduction in the potential for polluting the environment. Its high fibre content and low production costs mean that it could also be used as a dietary supplement to prevent diabetes, obesity and hyperlipidaemia. Chemical or enzymatic treatment, fermentation, extrusion, high pressure and micronisation can all increase the soluble fibre content, and thus improve nutritional quality and processing properties. However, the product also degrades rapidly due to its high moisture content (70–80%), which makes it difficult to handle and expensive to dry by conventional means. The aim of this paper is therefore to thoroughly study the existing literature on this subject in order to develop a general protocol for okara exploitation and valorisation. A cost/benefit analysis could drive the design of eco-friendly, sustainable protocols for the preparation of high-value nutritional products.

“…In previous studies, several polysaccharides were isolated from black soybean seed, and the typical polysaccharide, named PSBS, was composed of 89% glucose, 6% mannose and 5% galactose [ 24 ]. BSPS-1 and BSPS-2 were predominantly composed of glucose and galactose, and BSPS-3 was predominantly composed of galactose and arabinose [ 7 ]. These data indicated that mannose and galactose were the predominant monosaccharides in the new polysaccharide BSCP-1.…”

“…However, research on the high-polarity, water-soluble component has been relatively limited, especially regarding the structural elucidation of polysaccharides even though these compounds have proven to have health benefits for humans by lowering blood cholesterol, improving laxation and reducing the risk of diabetes, which was known before the 1990s [ 6 ]. Regarding the processing of black soybean seed, the soybean curd residue (namely, okara) is the dominant surplus material and is always regarded as waste [ 7 ].…”

In this study, the extraction of water-soluble polysaccharides from the seed coat of black soybean (BSCP) was investigated and optimized. A response surface methodology based on a Box-Behnken design (BBD) was used to optimize the extraction conditions as follows: extraction temperature, 100°C; ratio of water to material, 22.3 mL/g; and extraction time, 133.2 min. Under these conditions, the experimental yield of polysaccharides was 10.56%, which was consistent with the predictive yield. A novel galactomannan, BSCP-1, with a molecular weight of 7.55 × 105 Da determined by high-performance gel permeation chromatography, was isolated from the black soybean seed coat. Through gas chromatography-mass spectrometry analysis, BSCP-1 was identified as a galactomannan consisting of galactose, mannose and rhamnose in a molar ratio of 6.01:3.56:1.00. Cytotoxicity against the human gastric carcinoma cancer cell line was also determined.
