Effect of different rootstocks on PAL activity and phenolic compounds in flowers, leaves, hulls and kernels of three pistachio (Pistacia vera L.) cultivars

Phenol metabolism and preservation of fresh in‐hull walnut stored in modified atmosphere packaging

“…PAL activity was assayed according to the method of Nadernejad et al 23 with some modifications. Approximately 1 mL of the extraction buffer, 1 mL of 20 mmol L −1 L-phenylalanine, 0.4 mL of deionized water and 0.5 mL of enzyme extract were incubated at 37 ∘ C for 1 h. The reaction was terminated with the addition of 1 mL of 1 mol L −1 HCl.…”

Risk assessment of exposure to aflatoxin B1 and ochratoxin A through consumption of different Pistachio ( Pistacia vera L.) cultivars collected from four geographical regions of Iran

“…The composition of pistachio kernel may vary depending on the cultivar, cultivation site, climate, and horticultural practice (Agar et al, 1994 ▶; Nadernejad et al, 2012 ▶; Tajabadipour et al, 2005 ▶; Tavallali and Rahemi 2007 ▶; Tsantili et al, 2010 ▶). It is necessary to evaluate the effects of cultivar, rootstock, geographical and climatic condition on some characteristics of agricultural crops, like pistachio, and investigate the effects of these parameters on the amount of fatty acids, mineral elements and total protein in pistachio cultivars (Chahed et al, 2008 ▶; Küçüköner and Yurt, 2003 ▶).…”

Effects of a rotational UV‐C irradiation system and packaging on the shelf life of fresh pistachio

“…For extraction of phenolic compounds, methanolic solution containing 1% hydrochloric acid was added to 0.2 g of homogenized sample, stirred for 2 h, and centrifuged at 958× g for 10 min. The supernatant was collected to measure TPC using Folin–Ciocalteu method . The results are expressed as grams of gallic acid equivalents (GAE) per kilogram of fresh weight (FW) (g GAE kg −1 FW).…”
