However, scant data are available on the nutrient profiles of these products. In the present work, 38 samples of regular and reduced-fat varieties of four white brined cheeses (Akkawi, Halloumi, Double Crème and Braided) and Labneh, produced from cow’s milk, were analyzed for basic nutrients (water, protein, fat, ash and lactose), cholesterol and selected minerals (Na, Ca, K, Mg, P and Zn). The moisture contents of Labneh (78.6 g·100 g−1) and Double Crème (60.3 g·100 g−1) were higher than those of Akkawi, Halloumi and Braided cheeses (46.6–55.1 g·100 g−1). The fat content of full-fat Labneh was 8.8 g·100 g−1 while the full-fat brined cheeses contained fat levels between 18.3 and 23.9 g·100 g−1. Protein contents ranged between 8.9 and 24.8 g·100 g−1. Cholesterol strongly correlated with fat content and an increase in cholesterol/fat ratios was observed with decreasing fat levels. Sodium contents ranged between 151 and 5012 mg·100 g−1 while Ca levels ranged between 43 and 921 mg·100 g−1. The moisture contents indicated that Double Crème was a soft cheese while Akkawi, Halloumi and Braided cheeses were firm/semi-hard cheeses. The fat levels in dry matter (FDM) revealed that only full-fat Double Crème cheese with a FDM of 48 can be classified as full-fat while the other cheeses can be classified as medium fat, partially skimmed or skim. These data will be of use to dairy scientists and technologists, dietitians and bodies concerned with promoting healthier dietary practices. brined cheese / Labneh / composition / minerals / cholesterol 摘要 – 常规和低脂白卤干酪及浓缩酸奶 (Labneh) 中化学成分矿物元素和胆固醇含量○ 白卤干酪和浓缩酸奶是 (Labneh) 是地中海东部地区最普遍的乳制品○ 但是缺乏这些产 品营养方面的数据○ 本研究中,在四种白卤干酪中 (常规和低脂干酪) 中取 38 个样品 (Akkawi, Halloumi, Double Crème 和 Braided) 以及用牛奶制作的浓缩酸奶 (Labneh), 分析了这些样品最基本的营养成分 (水分、蛋白、脂肪、灰分、乳糖)、胆固醇及一些元 −1 −1 素 (Na,Ca,K,Mg,P,Zn)○ Labneh (78.6 g·100 g ) 和 Double Crème (60.3 g·100 g ) 的 *Corresponding author (通讯作者): [email protected] Article published by EDP Sciences 700 D.

Les fromages frais en saumure et le Labneh (lait caillé égoutté) sont les produits laitiers les plus populaires dans les pays situés à l’est du bassin méditerranéen. Cependant de rares données sont disponibles sur les profils nutritionnels de ces produits. Dans cette étude, 38 échantillons de 4 types de fromages frais en saumure (Akkawi, Halloumi, Double Crème et Braided) et de Labneh, à teneur normale ou réduite en matière grasse, produits à partir de lait de vache, ont été analysés pour leurs teneurs en nutriments basiques (eau, protéines, lipides, cendres, lactose), cholestérol et certains minéraux (Na, Ca, K, Mg, P, Zn). La teneur en matière grasse des Labneh « gras » était de 8,8 g·100 g−1 tandis que les fromages frais en saumure « gras » présentaient des teneurs en matière grasse de 18,3 à 23,9 g·100 g−1. Le cholestérol était fortement corrélé avec la teneur en matière grasse et une augmentation des ratios cholestérol/matière grasse était observée avec la réduction des niveaux de matière grasse. Les teneurs en sodium variaient entre 151 et 5012 mg·100 g−1 alors que les teneurs en calcium allaient de 43 à 921 mg·100 g−1. Les teneurs en humidité indiquaient que le Double Crème est un fromage à pâte molle, alors que l’Akkawi, l’Halloumi et le Braided sont des fromages fermes/à pâte demi-dure. Les niveaux de matière grasse sur extrait sec (G/S) montraient que seul le Double Crème à teneur non réduite en matière grasse peut être classé en fromage « gras » avec un G/S égal à 48, alors que les autres fromages peuvent être classés en « moyenne- ment gras », « partiellement maigre », ou « maigre ». Ces données seront utiles aux scientifiques et technologues du domaine laitier, aux diététiciens, et aux parties concernées par la promotion de pratiques alimentaires plus saines. fromage en saumure / Labneh / composition / minéraux / cholesterol 1.

Moreover, growing consumer practical means for preserving milk nutrients demand for low-fat/low-salt products, driven in a form that can be safely stored for by higher awareness of the perceived health extended periods of time at the high ambient risks associated with the consumption of temperatures in the region [16].
