概括

食品分类指标,如营养分类和NOVA,并不能预测味道的愉悦性. 高脂肪,高糖,高盐 (HFSS) 食物更有味道,但没有指标预测食物奖励.

科学领域:

食品科学食品科学食品科学
营养科学营养科学
感官科学感官科学

背景情况:

食品分类指标旨在预测消费者接受度和健康影响.
这些指标包括营养分类 (高口味食品 - - HPF),NOVA (超加工食品 - - UPF) 和营养分类 (高脂肪,高糖,高盐 - - HFSS).
之前的假设表明这些类别,特别是HPF和UPF,本质上是超可口的.

研究的目的:

为了评估三种食品分类指标 (营养素聚类,NOVA,营养素概况) 对食品口味的预测性表现.
为了确定这些指标是否可以预测人们的食欲 (食物奖励).

主要方法:

通过72至224名在线参与者获得的52种不同食品的口感评级进行了比较.
使用营养分类 (HPF),NOVA (UPF) 和营养分析 (HFSS) 评估食品的分类.
统计分析了食品类别之间的关系,并测量了口感和食物奖励.

主要成果:

在三种指标的食品分类中观察到明显的重叠,但也存在差异.
在超可口味食品 (HPF) 和非HPF之间,或在超加工食品 (UPF) 和非UPF之间,没有发现可口味的显著差异.
高脂肪,高糖和高盐 (HFSS) 食品的口味性与非HFSS食品相比显著更高.
这些指标都没有有效地预测食物奖励 (吃饭的欲望).

结论:

这些发现不支持使用营养聚类或NOVA指标作为味道的代理.
HFSS分类显示了一些可口度的预测值,与HPF和UPF指标不同.
准确预测口感要求在不同成分的食品中进行直接测量,而不是依赖基于成分的理论分类.

Key Elements for Plant Nutrition

Key Elements for Plant Nutrition

Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

Protein Networks

Protein Networks

An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...
