Attieke is an Ivorian semolina which obtained by fermenting, pressing and steaming cassava dough. Attieke production remains a traditional activity carried out by less literate women. However, perceived differences in measurable factors and attieke qualities require an investigation of their influence on the characteristics of the pressed dough and attieke. The aim of this study is to improve the quality of the dough in relation to that of the attieke produced. The experiment was carried out on 4 production factors, namely the type of boiled or braised ferment, the incorporation rate of the ferment between 8 and 10%, the addition of oil from 0.1 to 1% and the fermentation time from 12 to 15 hours applied to the Improved African Cassava (IAC) variety. A complete experiment design of 16 samples of fermented dough and attieke was employed. These samples underwent physic-chemical analyses for the fermented dough and sensory evaluation for the attieke. It was found that, except for titratable acidity, reducing sugar content and ash content, the physico-chemical characteristics of the dough of IAC variety were significantly influenced by all production factors and their interaction. Fermentation time significantly influences 60% of the physico-chemical characteristics of the fermented dough. The type of ferment, the oil addition and the ferment rate have a significant influence at 40% of these characteristics. At the sensory level, color, acidity and grain binding with an explained variance of 34.60% were essential for the appreciation of the attieke samples. Thus, these production factors could be considered for the improvement of the fermented dough and attieke production process.

Obesity has brought great challenges to global human health， and how to effectively prevent and control the occurrence and development of obesity has become an urgent problem. The role and mechanism of 4-[(α-L-Rhamnosyloxy) benzyl] isothiocyanate (MITC)， an active ingredient of Moringa oleifera Lam.， in the regulation of lipid metabolism have not been comprehensively investigated. In the present study， we investigated the mechanism of MITC in inhibiting lipid accumulation in mice fed with a high-fat diet (HFD) in terms of both lipolysis and central appetite regulation mediated by the gut microbe–gut–brain axis. MITC enhanced the characteristic indices associated with HFD mice and also promoted adipocytolysis and brown fat thermogenesis. Moreover， MITC was observed to improve leptin resistance， modulate the composition of gut microbiota such as Ruminococcaceae， Parasutterella， and Acetatifactor， promote 5-HT secretion， further enhance the secretion of glucagon-like peptide-1 (GLP-1) and peptide tyrosine-tyrosine (PYY) to activate peroxisome proliferator-activated receptor (PPAR) signaling in the hypothalamus， and modulate feeding behavior to inhibit lipid accumulation in HFD mice. These data suggest that MITC supplementation can help to alleviate obesity or obesity-related diseases.

The baobab, Adansonia digitata L., plays an important role in the economy of local populations. Nowadays, baobab seed oil is highly prized for its many cosmetic and therapeutic applications, and for its composition of unsaturated fatty acids, sterols, and tocopherols. However, it undergoes numerous reactions during production, processing, transport, and storage, leading to undesirable products that make it unstable. The aim of this study was to provide local processors with innovative solutions for the treatment of unrefined vegetable oils. To this end, an experimental device for filtering crude oil on activated carbon made from fruit capsules was designed. The results obtained after the treatment show a significant decrease at (p 2/Kg), chlorophyll concentration (1.81 to 0.50 mg/Kg) and primary and secondary oxidation products. According to these results, activated carbon’s adsorptive power eliminates oxidation products and certain pro-oxidants such as chlorophyll, resulting in a cleaner, more stable and better storable oil.

Oxygen heterocyclic compounds(OHCs) in lemon oils are important markers in targeted HPLC analyses for authentication

引用

food Science and Human Wellness 2024年

作者： Siyu Liu Shiming Li Chi-Tang Ho Department of food Science， Rutgers University New Brunswick College of Biology and Agricultural Resources， Huanggang Normal University

Lemon oils are broadly used as flavoring agents in beverages， foods， cosmetics and pharmaceuticals， yet the adulteration of natural， particularly cold pressed lemon oils is very common in the industry due to its unmet demand and high cost. Nowadays， most quality control (QC) analysis of lemon oils is conducted by gas chromatography (GC) analysis， which is far from a reliable method. Oxygen heterocyclic compounds (OHCs) in non-volatile fraction are gaining increasing attention in authentication process because of the nearly finger-printing profiles of OHCs in cold pressed citrus essential oils. Our goal in this study was to identify OHCs using high performance liquid chromatography (HPLC) in lemon oils， establish OHC profiles， perform stepwise logistic regression analysis (SLRA) and build effective predicting model and further determine adulterated lemon oils by referencing the OHC profiles and established models. After HPLC analyses， profiling and SLRA modeling of 154 OHCs samples of industrial lemon oils， we found that the combination of isopimpinellin and total OHC concentration are essential and robust predictors to differentiate authentic samples from adulterated lemon oils with a success rate of 98% from the 5-fold cross validation. This study provided a reliable and efficient method in determining the authenticity of lemon oils.

Chemical-assisted MMP reduction on methane-oil systems:Implications for natural gas injection to enhanced oil recovery

引用

Petroleum 2024年第1期10卷 101-108页

作者： Mohamed Almobarak Matthew B.Myers Colin D.Wood Yongbing Liu Ali Saeedi Quan Xie Discipline of Petroleum Engineering WA School of Mines: Minerals Energy and Chemical Engineering Curtin University Commonwealth Scientific and industrial Research Organization Curtin University Oil and Gas Innovation Centre Management State Key Laboratory of Oil and Gas Reservoir Geology and Exploitation

Miscible natural gas injection is widely considered as a practical and efficient enhanced oil recovery technique. However, the main challenge in this process is the high minimum miscibility pressure（MMP）between natural gas and crude oil, which limits its application and recovery factor, especially in hightemperature reservoirs. Therefore, we present a novel investigation to quantify the effect of chemicalassisted MMP reduction on the oil recovery factor. Firstly, we measured the interfacial tension（IFT） of the methane-oil system in the presence of chemical or CO2to calculate the MMP reduction at a constant temperature（373K） using the vanishing interfacial tension（VIT） method. Afterwards, we performed three coreflooding experiments to quantify the effect of MMP reduction on the oil recovery factor under different injection *** interfacial tension measurements show that adding a small fraction（1.5 wt%） of the tested surfactant（SOLOTERRA ME-6） achieved 9% of MMP reduction, while adding 20 wt% of CO2to the methane yields 13% of MMP reduction. Then, the coreflooding results highlight the significance of achieving miscibility during gas injection, as the ultimate recovery factor increased from 65.5% under immiscible conditions to 77.2% using chemical-assisted methane, and to 79% using gas mixture after achieving near miscible condition. The results demonstrate the promising potential of the MMP reduction to significantly increase the oil recovery factor during gas injection. Furthermore, these results will likely expand the application envelop of the miscible gas injection, in addition to the environmental benefits of utilizing the produced gas by re-injection/recycling instead of flaring which contributes to reducing the greenhouse gas emissions.
