Improving bioactivities of Jatropha curcas protein hydrolysates by optimizing with response surface methodology the extrusion cooking process

Response Surface Methodology Optimization of Ultrasonic-Assisted Extraction of Acer Truncatum Leaves for Maximal Phenolic Yield and Antioxidant Activity

“…Compared to other conventional methods, UAE offers a net advantage in terms of productivity and selectivity with shorter processing times, enhanced quality, reduced chemical and physical hazards, and it is environmentally friendly and causes less damage to the structural and molecular properties of compounds in plant materials [ 9 , 10 ]. For these reasons, UAE from plant materials has been widely used lately to facilitate extractions of phenols from Chrysanthemum morifolium flower heads [ 10 ], Olea europaea fruits [ 11 ], Morus nigra must [ 12 ], and Curcuma longa rhizomes [ 13 ], lipids from rice [ 14 ], polysaccharides from pumpkin [ 15 ] and mycelial fermentation of Phellinus igniarius [ 16 ], proteins from Jatropha curcas seeds [ 17 ], lignans from Schisandra chinensis fruits [ 18 ] and other value-added compounds from various natural resources. However, to the best of our knowledge, no report is available regarding improvements of phenolic yield by itself, let alone the phenolic yield together with antioxidant activity from ATL by using ultrasonic stimulation.…”

“…Being a valuable tool to investigate the interaction among factors and quantitatively depict the effects of given parameters on their measured responses [ 19 ], RSM is a collection of statistical and mathematical methods for developing, improving, and optimizing a process [ 20 ]. In comparison with single variable optimization methods, RSM is a time- and cost-effective means of simultaneously evaluating interactions as well as the key experimental parameters [ 21 ], thus have been wildly applied to optimize many bioprocesses [ 17 , 22 , 23 , 24 ]. Central composite design (CCD) used in RSM, is superior compared with the classical approach in terms of the comprehensiveness of information gained and the accuracy of the experiments conducted [ 22 , 25 ], thus is applied in the present study to optimize the UAE process.…”

Optimisation of antioxidant hydrolysate production from sweet potato protein and effect of in vitro gastrointestinal digestion

“…Protein hydrolysates, commonly generated from food proteins by enzymatic hydrolysis, present certain bioactivities that can be used in health care, such as antioxidant, antimicrobial, antihypertensive, immunostimulatory, antithrombotic and antidiabetic activities. (Agyei et al, 2016;Valdez-Flores et al, 2016). Antioxidant hydrolysates can scavenge free radicals and/or inhibit free radical formation, which plays an important role in delaying the oxidation of food system and is essential to the human health.…”
