Propriedade organoléptica

Chamam-se propriedades organolépticas às características dos materiais que podem ser percebidas pelos sentidos humanos, como a cor, o brilho, a luz, o odor, a textura, o som e o sabor[1][2]..

Estas propriedades são importantes em marketing, mas principalmente na avaliação do estado de conservação de alimentos, que frequentemente são sujeitos a um "exame organoléptico" para verificar se estão em boas condições para o consumo.

Cor

Um balão

A cor pode ser percebida pela visão, uma matéria pode possuir cor ou não, um exemplo de matéria incolor é a água, e um exemplo de matéria colorida é um balão.

Os alimentos, como a carne, o peixe e os vegetais, têm cores próprias e quando são apresentados com uma cor diferente podem ser rejeitados pelos consumidores, seja por uma questão de hábito, seja por mostrarem indícios de deterioração.

Sabor

Sabor é uma propriedade percebida com o paladar. As substâncias podem apresentar ou não sabor como no caso da água pura. Substâncias com sabor são os alimentos em geral.

Copo d'água

.

Odor

O odor é uma propriedade que pode ser percebida com o olfato. Uma flor, como a rosa, pode ter cheiro (odorífera) ou não (inodora). Os alimentos também têm o seu odor próprio e um odor diferente pode indicar que o alimento não se encontra em condições para consumo (por exemplo, odor a putrefação).

Textura

A textura é uma propriedade que pode ser percebida pelo tato e, do ponto de vista do consumidor, é importante, por exemplo, nos têxteis e nos alimentos.

In complex analysis, the open mapping theorem states that if U is a domain of the complex plane C and f : U → C is a non-constant holomorphic function, then f is an open map (i.e. it sends open subsets of U to open subsets of C, and we have invariance of domain.). The open mapping theorem points to the sharp difference between holomorphy and real-differentiability. On the real line, for example, the differentiable function f(x) = x2 is not an open map, as the image of the open interval (
