جهت بهینه سازی شرایط تولید پروتئین هیدرولیز شده (شامل نسبت آنزیم به سوبسترا، دما و زمان) به منظور دستیابی به بالاترین خواص آنتی اکسیدانی، مینس تهیه شده از ضایعات میگوی ببری سبز (penaeus semisulcatus) پس از تعیین درصد پروتئین آن (13%، بر اساس وزن تر) با استفاده از دو پروتئاز تجاری آلکالاز و فلاورزایم بر اساس 18 تیمار تعیین شده با طرح آزمایشات سطح پاسخ برای هر آنزیم، هیدرولیز شده و با خشک کن انجم...
in recent years many researchers have been focused on interaction of small molecules with dna. dna is generally the primary intracellular of anticancer drugs, so the interaction between small molecules and dna can cause dna damage in cancer cells, blocking the division of cancer cells and resulting in cell death. the flavonoids are a large group of polyphenolic natural products that are widely ...
in order to optimization of protein hydrolysis condition (including enzyme to substrate ratio (e/s), temperature and time) for achieving the highest antioxidant activity, the green tiger prawn (p. semisulcatus) mince was tested via commercial protease (alcalase® 2.4l) based on the response surface designed method in 18 treatments and then dried to obtain powder in freeze dryer. the antioxidant ...
ethanolic extract of leaves of elaeocarpus ganitrus was analyzed for their total antioxidant capacity, reducing power, metal chelating, abts+ (2, 2-azinobis-(3-ethylbenzothiazoline-6-sulphonate) radical scavenging and hydroxyl radical scavenging activities. the extract at 500 ?g/ml showed maximum iron chelating activity (76.70%) followed by the scavenging of the abts+ radical (55.77%) at the sa...
Background and Objectives: Bioactive peptides have different health benefits and functional characteristics and are produced by enzymatic hydrolysis, microbial fermentation and chemical synthesis methods. The purpose of this study was to optimize the enzymatic hydrolysis conditions of fenugreek seed protein with alcalase and to evaluate the antioxidant properties of the resulting peptides. Mate...

the present study was carried out to evaluate the antioxidant and free radical scavenging activity of methanolic extract of ervatamia coronaria leaves (apocynaceae) in various systems. dpph radical, superoxide anion radical, nitric oxide radical and hydroxyl radical scavenging assays were carried out to evaluate the antioxidant potential of the extract. the antioxidant activity of methanolic ex...
Background and Objectives: Antioxidants are used to decrease oxidation of oils and increase shelf life of foods for centuries. Nowadays, researchers investigate for the replacement of synthetic antioxidants with antioxidants from natural sources. The purpose of this study was to investigate effects of quinoa enzyme-hydrolyzed proteins on functional and antioxidant properties of the produced pep...
The present study was carried out to evaluate the antioxidant and free radical scavenging activity of methanolic extract of Ervatamia coronaria leaves (Apocynaceae) in various systems. DPPH radical, superoxide anion radical, nitric oxide radical and hydroxyl radical scavenging assays were carried out to evaluate the antioxidant potential of the extract. The antioxidant activity of methanolic ex...
