多酚,脂肪酸,在八个波斯核桃(JuglansregiaL.)样品中研究了矿物成分:\'Milotai10\'(M10)和\'Alsószentiváni117\'(A117)匈牙利品种,来自两个匈牙利种植区(Pálháza-P和Berzék-B),\'Chernivets\'ky1\'来自乌克兰,还有来自美国的钱德勒,智利,巴西在匈牙利消费市场购买。目的是从营养的角度揭示哪种核桃品种最适合食用。相比之下,在匈牙利气候条件下种植的两种匈牙利品种平均多含有约33%的多酚,SFAs(饱和脂肪酸)增加约22%,和大约27%更多的MUFA(单不饱和脂肪酸)。关于矿物,钙,镁,磷,在两个匈牙利品种中,钠的浓度都较高。在匈牙利培育的品种中,M10主要达到较高的化合物含量,但是水果现场条件的影响没有被清楚地检测到。其他品种主要含钾,铜,还有锌,比如从智利收获的钱德勒。\'Chernivets\'ky1\',从乌克兰收获,与其他受检品种相比,肉桂酸和亚油酸含量优异。与来自匈牙利的样品相比,所有“钱德勒”样品(主要是美国人)的PUFA含量增加了11%。
Polyphenols, fatty acids, and mineral composition were studied in eight Persian walnut (Juglans regia L.) samples: \'Milotai 10\' (M10) and \'Alsószentiváni 117\' (A117) Hungarian varieties derived from two Hungarian growing areas (Pálháza-P and Berzék-B), \'Chernivets\'ky 1\' from Ukraine, and \'Chandler\' from the United States of America, Chile, and Brazil purchased on the Hungarian consumer market. The aim was to reveal which walnut variety is the most suitable for consumption from a nutritive point of view. In comparison, both Hungarian varieties grown in Hungarian climatic conditions had on average approximately 33% more polyphenols, approximately 22% more SFAs (saturated fatty acids), and approximately 27% more MUFAs (monounsaturated fatty acids). Regarding the minerals, calcium, magnesium, phosphorus, and sodium were present in higher concentrations in both Hungarian varieties. Among the Hungarian-bred varieties, M10 mainly reached a higher compounds content, but the effects of the fruit site conditions were not clearly detected. Other varieties contained mainly potassium, copper, and zinc, such as \'Chandler\' harvested from Chile. \'Chernivets\'ky 1\', harvested from Ukraine, had outstanding cinnamic acid and linoleic acid contents compared to the other examined varieties. All \'Chandler\' samples (mainly the American) contained 11% more PUFAs compared to the samples derived from Hungary.
