PROBLEM TO BE SOLVED: To provide a carrier capable of safely exerting a function.SOLUTION: A freshness preserver is so configured that carrier materials 2 including palladium chloride (PdCl) are supported by a carrier 1, and each carrier material 2 includes palladium (Pd), alkali metal element, and chlorine (Cl) as constituent elements. In the carrier material 2, a composition ratio of the palladium is 0.001 mass%-0.1 mass%, a composition ratio of the alkali metal element is 0.004 mass%-20 mass%, and a composition ratio of the chlorine is 0.002 mass%-5 mass%. When a mole ratio of the palladium is defines as 1, a mole ratio of the alkali metal element is 5-300, and a mole ratio of the chlorine is 5-300.SELECTED DRAWING: Figure 1 【課題】安全に機能を発揮することが可能な担持体を提供する。【解決手段】鮮度保持剤では、塩化パラジウム（ＰｄＣｌ2）を含む担持材料２が担体１により担持されており、その担持材料２は、パラジウム（Ｐｄ）と、アルカリ系金属元素と、塩素（Ｃｌ）とを構成元素として含む。担持材料２中において、パラジウムの組成比は０．００１質量％〜０．１質量％、アルカリ系金属元素の組成比は０．００４質量％〜２０質量％、塩素の組成比は０．００２質量％〜５質量％である。パラジウムのモル比を１としたとき、アルカリ系金属元素のモル比は５〜３００、塩素のモル比は５〜３００である。【選択図】図１
