The use of animal fats as raw material for shortening production has been avoided because of low supply, and religious restrictions of certain beliefs. The use of hydrogenated vegetable oils is also avoided because that may induce cardiovascular diseases. Palm oils and soya bean oil are theoretically potentials to be used as raw materials for shortening manufacturing due to their triacylglycerols composition and these oils can be easily modified to achieve desirable plasticity. In this study, shortening was produced by formulating a blend of palm stearin and soya bean oil in varying proportions. Physicochemical properties, product stability, and sensory acceptability of the processed shortening were determined. Stability tests of the processed shortening were determined for 6 months at two months intervals. The acidity, peroxide value, and free fatty acid values were increased with storage time and storage temperature. The physicochemical properties of the processed shortening samples were within the requirements of the food domain. The samples stored at 37 °C exhibited the highest acid, peroxide, and free fatty acid values throughout storage time. In conclusion, shortening produced from 60% palm stearin (S60) and stored at room temperature has shown a good physicochemical characteristic and is well accepted for different sensory attributes.

This study aimed to compare the conventional soybean ( L.) cultivation method with integrated systems in an Latossolo Vermelho Acriférrico típico and how these systems affect soil cover biomass production, initial nutrient concentration in plant residues, soil respiration and microclimate, as well as soybean growth, physiology and productivity. A comparative analysis of microclimate and soil respiration, plant physiology, and growth was conducted between a conventional soybean monoculture (soybean grown without plant residues on the soil from the previous crop) and soybean grown in soil containing maize residues.

The morbidity of the chronic diseases such as the hypertension and cardiovascular diseases has been increasing in recent decades. The unhealthy diet with excessive salt intake is one of the proegumenal causes. In this research, spherical hollow salt particles with high specific surface area and durable ginger flavor were prepared as a seasoning powder for salt reduction and saltiness enhancement in solid foods.

This study aims to enhance the emulsifying properties of soybean peptide aggregates (SPA) by preparing SPA-soluble soybean polysaccharide (SSPS) composite particles at the assistance of ultrasound technique. The optimal pH for SPA and SSPS complexation was determined by measuring the charge and particle size of the composites. The effects of ultrasound power and duration on the physicochemical properties of the composite particles were assessed through measurements of particle size, zeta potential, contact angle, FTIR, and SEM.

Soy extract waste, okara, is a rich source of bioactive compounds such as isoflavones, which are phytoestrogens with potential health benefits. To develop a green approach to recovering these compounds and valorizing okara, a study was developed to screen variables for the extraction of isoflavones from okara and soybean (for comparison) using Deep Eutectic Solvents (DES) composed with choline chloride ([Ch]Cl) and acetic acid (AA) ([Ch]Cl: AA, 1:2). A fractional design (2) was used to evaluate variables in the extraction of isoflavones, followed by a Central Composite Rotatable Design (CCRD).
