Example Embodiment

[0021] Implementation case 7-9 The fading prevention effect of gardenia yellow pigment

[0022]

[0023]

[0024] Add the color protectant of the present invention to the above noodles to make the 3 types of noodle products in this case. The above combinations are mixed, kneaded, calendered, cut, steamed, packaged, heat sterilized, and cooled according to conventional methods. Invented color retention agent. Under room temperature conditions, the color of the noodles was measured with a color difference meter after irradiating with a 3500 Lux fluorescent lamp for 3 days, 6 days, and 10 days. The Lab value of the noodles was measured, and ΔE (color difference) was calculated. The results are shown in Table 2. It can be seen from Table 2 that the color retention agent of the present invention can effectively prevent the fading of gardenia yellow pigment. ΔL for color difference (ΔE) 2 +Δa 2 +Δb 2 The square root of, the larger the value, the larger the color change (fading).

Abstract

The invention discloses a gardenia yellow pigment colour retention agent containing chlorogenic acid substances and a preparation method thereof. The gardenia yellow pigment colour retention agent disclosed by the invention contains the chlorogenic acid substances, wherein the chlorogenic acid substances comprise chlorogenic acid, caffeic acid, ferulic acid, 3,5-dicoffee acyl quininic acid and neochlorogenic acid. The chlorogenic acid substances can effectively prevent gardenia yellow pigment from fading and can be taken as a colour retention agent of the gardenia yellow pigment, and the chlorogenic acid substances can be taken as the colour retention agent, can be widely applied to the food field, is especially applicable to food and drink which contain the gardenia yellow pigment, can not influence flavour of the food and has an excellent colour retention effect.

Description

technical field [0001] The invention relates to the field of pigment color-protecting agents, more specifically, relates to a gardenia yellow pigment color-protecting agent and a manufacturing method thereof. Background technique [0002] In the past, synthetic colorings were widely used as food colorings, but people began to replace synthetic colorings with natural colorings after discovering the safety problems of synthetic colorings. Now, natural pigments mainly including gardenia yellow pigment, capsanthin, cabbage red pigment, safflower yellow pigment and gardenia blue pigment are widely used in food, beverage, cosmetics, health care, pharmaceuticals and other fields, especially It is widely used in food and beverage. However, compared with synthetic pigments, natural pigments are unstable, and will change in color due to factors such as light, oxygen, and temperature, and may fade, thereby reducing the value of the product. At the same time, the natural pigment mainl...
