Embodiment Construction

[0017] The following is a specific embodiment of the present invention, which will now be further described.

[0018] A processing method of dehydrated carrots includes the following steps:

[0019] ① Material selection;

[0020] Choose mature carrots that are complete, clean, bright in color, and have no mildew and spoilage as raw materials;

[0021] ②Ultrasonic cleaning and peeling;

[0022] The selected carrots are placed in saturated brine containing sodium hydroxide and sand with a diameter of 1.5 ~ 5.0 mm, and ultrasonic waves are applied to the saturated brine using an ultrasonic generator. The frequency and sound intensity of the ultrasonic waves are 5 kHz ~ 1 MHz and 0.2 ~ respectively. 10W / cm2, duration 10-15 minutes;

[0023] ③Cut the carrots into cubes and soak them in sodium hydroxide solution for 10-15 minutes;

[0024] ④ Cleaning and screening;

[0025] Wash the carrots in a cleaning appliance to remove the grit, sodium hydroxide and sodium chloride solution residue left by...

Abstract

The invention discloses a processing method of dehydrated carrots, and belongs to the technical field of food preparation. The processing method comprises the following steps that 1, material selecting is conducted; 2, ultrasonic cleaning and peeling are conducted; 3, carrots are cut into cubes or strips and then soaked with a sodium hydroxide solution for 10 min to 15 min; 4, cleaning and screening are conducted; 5, steam blasting is conducted; 6, cooling is conducted, wherein the product obtained in the previous step is put in a screen mesh to be washed with a citric acid solution and cooled for 15 min to 20 min; 7, drying and packaging are conducted. According to the method, sodium hydroxide is added in the ultrasonic cleaning and peeling process, color protection treatment is conducted on the carrots while peeling is conducted, the efficiency is high, and the caring effect is good; soaking is conducted with the sodium hydroxide solution before steam blasting, and therefore the condition that the ingredients such as pigments of the carrots are destroyed in the processing process is prevented; when cooling is conducted, washing is conducted with the citric acid solution to achieve further color protection treatment on the carrots, and then the dehydrated carrot processed product with the good appearance and the excellent taste is made.

Description

Technical field [0001] The invention relates to the technical field of food preparation, in particular to a method for processing dehydrated carrots. Background technique [0002] Dehydrated vegetables are convenient to eat, have less water content, have a long storage time, and are easy to transport. They can effectively regulate the off-peak and peak seasons of vegetable production, which is beneficial to their use in daily life. But at present, after processing carrots into dehydrated vegetables, due to improper technology, it is easy to cause the loss of nutrients and the destruction of color and taste, which affects its quality. Summary of the invention [0003] In order to solve the above technical problems, the present invention provides a method for processing dehydrated carrots. [0004] The present invention is realized by the following technical solutions: a processing method of dehydrated carrots, including the following steps: [0005] ① Material selection; [0006] ②Ult...
