Abstract：
Aging is accompanied by a decline in appetite and food intake with associated deficiencies in both macronutrients and micronutrients. The aim of this study was to investigate the impact of adding Iranian brown sumac (Rhus coriaria) (CIBS) into butternut squash soup on sensory evaluation and food intake among older adults (n = 20; >65 years old) and younger adults (n = 20; 18-35 years old). To evaluate the polyphenol content and antioxidant activity of the sumac samples, a Folin-Ciocalteu assay (FCR) and ferric ion reducing antioxidant power (FRAP) assay were used, respectively. L-glutamic acid was assessed using a Megazyme L-glutamic acid assay. Compusense software was used to assess the sensory evaluation attributes of free-living older adults and younger adults receiving different doses of sumac in butternut squash soup. Nutritics software was used to assess food intake following the addition of 0.37 g of sumac to soup. CIBS was selected based on a preliminary assessment in vitro for L-glutamic acid, antioxidant, and polyphenol content of six varieties of sumac. Sensory evaluation results revealed that the difference in perceived intensity of brown color between the soup samples with different doses of CIBS was greater in the younger adults\' group (p = .001) than in older adults (p = .037). In addition, the food intake study found that during the ad libitum lunch, older adults consumed more energy (kcal; p = .014), protein (g; p = .025), carbohydrate (g; p = .013), and fat (g; p = .002) after soup with sumac compared to control soup. The overall findings of this study suggest that the addition of sumac to food may have a potential benefit in enhancing ad libitum lunch intake in older adults leading to effective management of malnutrition. This may promote healthy aging and minimize the burden and the consequences of anorexia of aging as main public health concerns.
摘要：
衰老伴随着食欲和食物摄入的下降,伴随着大量营养素和微量营养素的相关缺乏。这项研究的目的是调查在胡桃南瓜汤中添加伊朗棕色漆树（Rhuscoriaria）（CIBS）对老年人（n=20；>65岁）和年轻人（n=20；18-35岁）的感官评价和食物摄入的影响。为了评估漆树样品的多酚含量和抗氧化活性，a使用Folin-Ciocalteu测定法（FCR）和三价铁离子还原抗氧化能力（FRAP）测定法，分别。使用MegazymeL-谷氨酸测定法评估L-谷氨酸。Compusense软件用于评估在胡桃南瓜汤中接受不同剂量漆树的自由生活的老年人和年轻人的感官评估属性。在向汤中添加0.37g漆树后，使用营养学软件评估食物摄入量。CIBS是根据体外L-谷氨酸的初步评估选择的，抗氧化剂，6个漆树品种的多酚含量。感官评估结果表明，不同剂量CIBS的汤样品之间棕色颜色的感知强度差异在年轻人组中（p=.001）大于老年人组（p=.037）。此外,食物摄入研究发现，在随意享用午餐期间，老年人消耗更多的能量(大卡；p=0.014)，蛋白质（g；p=.025），碳水化合物（g；p=.013），与对照汤相比，用漆树汤后的脂肪（g;p=0.002）。这项研究的总体结果表明，在食物中添加漆树可能对增加老年人的随意午餐摄入量具有潜在的益处，从而有效地管理营养不良。这可能会促进健康的衰老，并最大程度地减少衰老的负担和厌食症的后果，这是主要的公共卫生问题。
