Soybean hull as a rich and inexpensive source of dietary fiber and because of its health properties, is a good option for supplying dietary fiber to various food industries. Optimization of the extrusion process and the effects of its variables [Feed moisture (35-45%), screw speed (160-200 rpm), and temperature (75-95 °C)] were investigated on the structural, nutritional, and functional properties of soybean hull by response surface methodology. Based on response surface analysis, the maximum soluble dietary fiber content and water absorption index in addition to the minimum specific mechanical energy and anti-nutritional composition of tannin were obtained at a feed moisture content of 42.58%, screw speed of 182.46 rpm, and temperature of 87.43 °C. The extrusion process also increased the rate of swelling capacity, solubility index, yellowness, and redness of the samples. It also reduced the oil absorption index and lightness in comparison with the control. The FTIR spectroscopy did not show a new functional group and the urease test (trypsin inhibitor activity) was negative in the extruded samples.Peanut (Arachis hypogaea) is an important oilseed crop of the world. Peanut seed oil (PSO) contains linolenic acid, oleic acid, also a good source of omega-6 fatty acids and omega-3 fatty acids. It contains an abundant amount of vitamin E which also act as an antioxidant. The research work was carried out to estimate the suitability of utilization of peanut oil from different available peanut varieties, i.e., Bari 2001, Bari 2011 in cereal-based products. The main objective of the study is the characterization of peanut seed oil acquired from Bari 2001 and 2011 variety, and explored its application in cookies and shelf life of the product. The purpose of the study is to determine the oil contents and characterization, its application in cookies and shelf life of the product. The data thus collected was analyzed by applying standard statistical procedures. Peroxide, saponification, and free fatty acids in Bari 2001 and Bari 2011 were 1.51 ± 0.09 meq O2/kg and 1.47 ± 0.07 meq O2/kg, 195.81 ± 2.47 mgKOH/g and 191.60 ± 2.66 mgKOH/g and 0.96 ± 0.07% and 0.91 ± 0.04% respectively. Cookies were prepared by incorporating PSO oil (Bari 2011) at concentrations of 5% (FC1), 10% (FC2), 15% (FC3), 20% (FC4), 25% (FC5) and along with control (FC0). Storage study (60 days) assessed the quality, sensory evaluation and oxidative stability of products in order of most suitable to least accepted as FC3 > FC4 > FC5 > FC1 > FC2 > FC0. The cookies produced by 15% replacement peanut seed oil resulted in an acceptable product.Virgin coconut oil (VCO) and propylene glycol (PG) have received more attention as bio-based solvents for natural bioactive recovery in green extraction process. Here, maceration extraction and ultrasound-assisted extraction (UAE) of bioactive phenolics from mangosteen peel (MP) by VCO, PG and VCO-PG mixture were compared. The goal was to maximize the phenolic extraction and improve bioactivities. Based on a single-factor experiment for UAE with VCO, the optimal condition was sample to solvent ratio of 16.6 g/mL, amplitude of 55 µm, and extraction time of 7 min, which yielded total phenolic content of 365 mg GAE/100 g. Regarding the extraction methods and bio-based solvents, UAE with mixed VCO-PG was not only provided greater polyphenol yield in a shorter time, but it also enhanced the bioactivities (radical scavenging, antibacterial, and antidiabetic activities) of the extract. Therefore, UAE can be potentially used in combination with bio-based solvents, especially mixed VCO-PG, for maximizing bioactive phenolic isolation from MP. This study provided an alternative method for production of bio-based oil solution from MP which can be directly used as a functional ingredient in emulsion based food, neutraceutical and cosmetic products.The relationship existing between operating parameters like speed of operation, applied pressure, feed rate and dependent variables like oil recovery and throughput capacity was investigated while mechanically expressing oil from kernels of Pentaclethramacrophylla. A 3-factor, 5-levels central composite design of response surface methodology was used for modeling and optimization of the process. GSK-2879552 in vitro The speed was varied over 15, 30, 45, 60 and 75 rpm using pulley arrangement, applied pressure was varied over 5, 10, 15, 20 and 25 MPa by adjusting the wormshaft distance of the oil expeller and the feed rate was varied over 100, 200, 300, 400 and 500 g/min by regulating the quantity of kernels fed into the expeller. Developed models were validated by comparing predicted values with experimental values. In optimizing the process, the oil recovery and throughput capacity were maximized while the independent variables were set at ranges. Optimum oil recovery of 73.2% and throughput capacity of 4.18 kg/h was obtained at 45 rpm speed of operation, 20 MPa applied pressure and 300 g/min feed rate. A quadratic polynomial model was developed for the oil recovery while a two-factorial-interaction model was developed for the throughput capacity. The results showed that speed of operation, applied pressure and feed rate had significant influence on the oil recovery and throughput capacity. The models developed were valid as they showed a good agreement between the variable due to low variations between calculated and predicted values.In present study kinetic, thermal and rheological characteristics of oil isolated from flaxseed were studied and because of high content of α-linolenic acid (essential omega-3 fatty acid), flaxseed oil was incorporated in muffins by replacing fat/shortening at different levels (10%, 20%, 30% and 40%). To evaluate rheological behaviour, the experimental data of flow behaviour for flaxseed oil was fitted to Power law model, consistency index (K) and flow behaviour index (n) and Arrhenius parameters (activation energy and frequency factor) were evaluated. The n value of the oil treated at 10, 15, 20, 25 and 30 °C were found between 0.8 to 0.9, which suggested the non-Newtonian fluid behaviour of flaxseed oil. Thermal properties of flaxseed oil was evaluated using DSC (differential scanning calorimetry). The flaxseed oil possessed three endothermic and one shoulder peak. Gas chromatography revealed the fatty acids composition qualitatively and quantitatively and flaxseed oil is dominated by unsaturated fatty acids.
