Plasma-Activated Water Affects the Antioxidant Contents in Water Spinach

Understanding Alkaline Antioxidant Water - Ionized Water

Protein Extraction from Water Spinach (ipomoea Aquatica)

Extractability of protein in water spinach (Ipomoea aquatica Forsk., I. reptans Poir), a possible source of food protein concentrate was examined. Fresh and fresh frozen leaves were extracted by the conventional bufferhomogenate method at room temperature and by a method involving pre-treatment of the leaves with polar and nonpolar solvents. Pre-treatment of leaves with dimethylsulfoxide (DMSO)...

Long-term antibacterial efficacy of air plasma-activated water

Indirect air dielectric barrier discharge in close proximity to water creates an acidified, nitrogen-oxide containing solution known as plasma-activated water (PAW), which remains antibacterial for several days. Suspensions of E. coli were exposed to PAW for either 15 min or 3 h over a 7-day period after PAW generation. Both exposure times yielded initial antibacterial activity corresponding to...

Promoting lentil germination and stem growth by plasma activated tap water, demineralized water and liquid fertilizer

Tap water, demineralized water and liquid fertilizer have been activated using an atmospheric pressure plasma jet (APPJ) to investigate their benefits for the germination rate and stem elongation rate of lentils from Puy-en-Velay (France). By plasma-activating tap water, we have obtained germination rates as high as 80% (instead of 30% with tap water). Also, higher stem elongation rates and fin...

Along-vein necrosis as indicator symptom on water spinach caused by nickel in water culture

Water spinach (Ipomoea aquatica Forsk, cv. Bamboo-Leaf) grown in aerated nutrient solution in greenhouse was treated with various levels of nickel, copper, zinc, chromium, cadmium, manganese, arsenic, aluminum, and lead. Injury symptoms caused by these metals were compared with each other. Among these metals, only nickel produced specific symptoms of along-vein necrosis on leaves and stems. Lea...
