To maintain a consistent composition, the individual components can be added to the original wax gelator. The content of hydrocarbons and wax esters greatly affects the structuring process of liquid edible oils with waxes. The aim of this study was to evaluate the possibility of modifying the properties of beeswax as a gelling agent by adding hydrocarbons or monoesters to obtain oleogels with specific properties. Various tests were conducted to assess the changes in the oleogel properties, such as color, microstructure, oil-binding capacity, thermal and textural properties. The research results have shown that the addition of the studied fractions has led to a significant change in all properties of oleogels. The initial size of oleogel crystals (7.29 ± 1.80 μm) changed after adding fractions, varying from 5.28 μm to 12.58 μm with hydrocarbons and from 9.95 μm to 30.41 μm with wax esters. The addition of 30%–50% hydrocarbons decreased the ability of the oleogels to bind oil and made them less firm compared to samples with 10%–20% hydrocarbons. Adding 10%–20% monoesters increased the firmness of the oleogels, but this indicator decreased when their content was increased to 50%. The obtained data indicate that hydrocarbons and wax esters can be used for targeted correction of the gelling properties of beeswax.</p></div>","PeriodicalId":33614,"journal":{"name":"Grain Oil Science and Technology","volume":"7 2","pages":"Pages 96-104"},"PeriodicalIF":0.0,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2590259824000050/pdfft?md5=ebbc63f74dbfc675bd8bd902da3159b8&pid=1-s2.0-S2590259824000050-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139538626","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During sourdough fermentation of cereals, biotransformation of nutrients occurs, resulting in notable changes to proteins, carbohydrates, fats, vitamins, and minerals. Each nutrient undergoes specific transformations, providing various advantages for human health. Proteins undergo hydrolysis to produce small molecular weight peptides and amino acids that are more easily digested and absorbed by the human body. Carbohydrates break down to improve the digestibility and absorption of cereals and lower the glycemic index. Fatty acids experience oxidation to produce new substances with health benefits. Additionally, the application of sourdough fermentation can enhance the texture, flavor, and nutritional value of cereal foods while also extending their shelf life and improving food safety. In conclusion, sourdough fermentation has a broad range of applications in cereal food processing.

The starch property results showed that a higher SPC is associated with lower turbidity, storage and loss modulus after storage, and water solubility, but higher swelling power (SP) and pasting viscosities. These findings suggested that SPC inhibited molecular rearrangement during storage and starch leaching during heating, and enhanced swelling and viscosities due to increased hydration and water uptake caused by the repulsion effect of phosphate groups and a less ordered crystalline structure. Increased SPC also resulted in lower resistant starch (RS) content in a native granular state but higher RS after retrogradation. Pearson correlations further indicated that SPC/C3P/C6P were positively correlated with peak (<em>r</em>² = 0.925, 0.873 and 0.930, respectively), trough (<em>r</em>² = 0.994, 0.968 and 0.988, respectively), and final viscosities (<em>r</em>² = 0.981, 0.968 and 0.971, respectively).

However, the unreasonable utilization of corn cob often causes the environmental pollution, waste of resources and other problems. As one of the most abundant polymers in nature, xylan is widely used in food, medicine, materials and other fields. Corn cob is rich in xylan, which is an ideal raw material for extracting xylan. However, the intractable lignin is covalently linked to xylan, which increases the difficulty of xylan extraction. It has been reported that the deep eutectic solvent (DES) could preferentially dissolve lignin in biomass, thereby dissolving the xylan. Then, the xylan in the extract was separated by ethanol precipitation method. The xylan precipitate was obtained after centrifugation, while the supernatant was retained. The components of the supernatant after ethanol precipitation were separated by the rotary evaporator. The ethanol, water and DES were collected for the subsequent extraction of corn cob xylan. In this study, a novel way was provided for the green production of corn cob xylan. The DES was used to extract xylan from corn cob which was used as the raw material. The effects of solid-liquid ratio, reaction time, reaction temperature and water content of DES on the extraction rate of corn cob xylan were investigated by the single factor test. Furthermore, the orthogonal test was designed to optimize the xylan extraction process. The structure of corn cob xylan was analyzed and verified. The results showed that the optimum extraction conditions of corn cob xylan were as follows: the ratio of corn cob to DES was 1 : 15 (g : mL), the extraction time was 3 h, the extraction temperature was 60 °C, and the water content of DES was 70%. Under these conditions, the extraction rate of xylan was 16.46%. The extracted corn cob xylan was distinctive triple helix of polysaccharide, which was similar to the structure of commercially available xylan. Xylan was effectively and workably extracted from corn cob by the DES method.
