Do you dare to eat the colorful food

Colorful is the way that nature shows itself. Color is the external appearance. We can interpret the internal health information of food through color. Food is closely related to color. Color, aroma, taste and shape are the four major elements of food. Vision is an important source of information for human beings. All natural and healthy foods have natural and healthy colors.

But now, more and more things with bright colors and people appear in our food, such as the hot fried zombie meat. It is difficult to distinguish its appearance and color from fresh meat through various additives.

Some “corn steamed buns” on the market feel soft and delicate. They can not feel the smell of corn when eating, and their color is too yellow to be true. This kind of “corn steamed bread” is likely to be added with additives such as pigment, which is mainly lemon yellow.

Dyed peanuts
Because the retail price of red and purple peanuts on the market is higher than that of white peanuts, many vendors use peach pigment to dye white flowers red before frying peanuts for petty profit.

Dyed black sesame
Normal black sesame seeds will appear slight discoloration after being soaked in water, but the color will not be too dark. The natural pigment in black sesame has a process of dissolving in water, so raw black sesame will not fade quickly when placed in cold water at room temperature, except for aged black sesame.

Dyed yellow croaker
Some illegal traders dye yellow croaker and pretend to be yellow croaker. This dye is often chemical dye, such as jade yellow, which is harmful to human health after eating.

Some extra white mushrooms appeared in the vegetable wholesale market, and were tested to be coated with fluorescent substances. Fluorescent bleach has strong bleaching effect. Soak mushrooms in water with fluorescent bleach, they will become white and bright, prolong the preservation time of mushrooms, and maintain the color of products.

Dyed orange
Orange is a popular fruit, but consumers must be careful when choosing oranges. The dyed orange looks very red on the surface.

Dyed millet
At the farmers’ market, some dyed millet was found for sale. The so-called dyeing refers to that when millet becomes mouldy and loses its edible value, speculators rinse it and then dye it with yellow pigment to make it bright yellow and deceive buyers. People will hurt their bodies if they eat the dyed yellow rice.

Dyed black rice
When the bought black rice is discolored, beware of the “dyed black rice”. The selection of black rice can be judged by “one look and two smells”.

How to distinguish between natural or synthetic pigments?
Look at the table of food ingredients:
There are 7 varieties of edible synthetic pigments approved for use in China, namely amaranth, carmine, allure red, lemon yellow, sunset yellow, indigo and brilliant blue. It is illegal to use more than these seven varieties. At the same time, according to China’s Hygienic Standard for the Use of Food Additives, the amount of food pigment used shall not exceed 0.1g/kg.

According to the shelf life of food:
Because natural pigments are easy to react with other additives in food, and are unstable and easy to decompose in the air, the shelf life of food using natural pigments is generally short. If the shelf life of food is long, it is almost impossible to dye it with natural pigments.

Look at the food color:
In fact, this is a simple method. Food dyed with natural pigments is generally light in color and looks natural. Especially bright colors that do not exist at a glance are naturally artificial pigments.

But sometimes our eyes will deceive us, so how can we better distinguish colors? In production and life, it is often necessary to accurately identify colors. What kind of instrument is needed to accurately measure colors? How does a color measuring instrument measure color accurately? Where can I use a colorimeter?
