Description

Application of DHA oil and fat composition in gelatin candy, gelatin candy and preparation method thereof Technical field

The invention relates to the technical field of food processing, in particular to the application of DHA oil and fat composition in gelatin candy and a gelatin candy and preparation method thereof.

Background technique

Docosahexaenoic acid (DHA) is a long-chain polyunsaturated fatty acid. It is mainly present in the gray matter in the brain. It is the main lipid component in human brain nerve cells and the fatty acid component that brain cells preferentially absorb and utilize. . The content of DHA in visual nerve cells and retinal tissue is as high as 40-47%, which plays an important role in the normal function of the photoreceptor. If DHA is lacking in food, the content of DHA in the retinal tissue can be reduced, resulting in vision and resolution decline. DHA can also reduce thrombosis and prevent cardiovascular diseases. At the same time, DHA also plays a significant role in delaying aging, preventing neurological diseases (such as preventing dementia, slowing down the condition of bipolar disorder, etc.), anti-cancer, inhibiting tumors, preventing osteoporosis, preventing diabetes, and anti-inflammatory.

The World Health Organization (WHO) and the American Medical Research Institute (IOM) unanimously recommend that pregnant and lactating women receive a daily DHA intake of 200 mg, and healthy people should have a minimum daily intake of 160 mg. Children aged 4-18 years The daily intake is 90-160mg. However, the daily intake of pregnant women, lactating women, children and adults in my country is far below this level.

EPA can inhibit the synthesis of liver fat and lipoprotein, promote cholesterol excretion, reduce triglyceride and low-density cholesterol in the blood, and increase beneficial high-density cholesterol. Effectively prevent the occurrence of hyperlipidemia. It can inhibit platelet aggregation and reduce the formation of thrombus. At the same time dilate blood vessels, reduce blood viscosity, increase red blood cell plasticity, improve platelet membrane fluidity, and help maintain the smoothness of blood vessels. Reduce the incidence of atherosclerosis, thereby reducing the incidence of cardiovascular and cerebrovascular diseases.

However, during the research, the inventor found that the EPA's "vascular scavenger" effect would have a negative effect on infants and young children: after extensive research, it has been shown that EPA has the ability to reduce blood viscosity and dilute Due to the role of blood, accumulation in pregnant women and infants is likely to cause abnormal bleeding. In addition, EPA will metabolize into prostacyclin PG3 in the human body and promote the premature puberty of children.

This embodiment is used to explain the gelatin candy provided by the present invention and its preparation method

The preparation of the gelatin candy was carried out according to the method of Example 1, except that in step (3), the gelatin candy was dried without washing the residual oil.

Test Example 1

(1) Color change

The color change is judged by observing the color change of the gelatin candy. Among them, the gelatin candy is light yellow and is scored as 10 points, and the light reddish brown is recorded as 1 point. Among them, the lower the score value, the more severe the color change. 1. (2) After removing the gelatin candy prepared in Examples 1-15 from the packaging, obtain the packaged DHA oil and fat composition, and perform a peroxide value (measured by a UV spectrophotometer according to the method of GB/T24304-2009), Determination of anisidine value (measured by GB/T 24304-2009 method) and acid value (measured by GB 5009.229-2016 method), the results are shown in Table 1.

It can be seen from Table 1 that the present invention can prepare gel candies containing DHA oil and fat compositions that meet the needs of different people, meet the requirements of different people for DHA and EPA, maintain the brain function of infants and young children, and promote their brain and vision The development of the system prevents the occurrence of side effects such as abnormal bleeding and precocious puberty. At the same time, it can regulate the blood lipids of middle-aged and elderly people, reduce blood coagulation, and prevent senile dementia. In addition, the method of the present invention can effectively slow down the oxidation of DHA and EPA in oils and fats, reduce the anisidine value, peroxide value and acid value of DHA oil and fat compositions, control the color change of gelatin candy, and increase DHA oil gelatin candy Save time.

The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited thereto. Within the scope of the technical concept of the present invention, a variety of simple modifications can be made to the technical solution of the present invention, including the combination of various technical features in any other suitable manner. These simple modifications and combinations should also be regarded as the disclosure of the present invention. All belong to the protection scope of the present invention.
