Problems solved by technology

However, since the fatty acids contained in perilla seed oil are almost all unsaturated fatty acids, they are easily oxidized and rancid, lose their original flavor and mouthfeel, and even produce substances harmful to human body. Therefore, how to inhibit the growth of perilla seed oil Oxidative rancidity, thus prolonging the shelf life of perilla seed oil is of great significance
In the prior art, Nanchang University proposed a patent application titled "A Method for Prolonging the Shelf Life of Perilla Oil" with application number 201510685644.3, which discloses adding 0.01-0.02% TBHQ, 0.005%-0.01% citric acid, 0.01%-0.1% degreased perilla seed extract, the method of prolonging the shelf life of perilla seed oil, has the disadvantage that the TBHQ used is a non-natural antioxidant, adding The measurement needs to be strictly controlled, and the preparation of the defatted perilla seed extract is cumbersome, which increases the complexity and cost of the preparation of perilla seed oil products

Embodiment 1

[0020] 1. Accurately weigh 4 parts of 1000g freshly squeezed perilla seed oil, 1 part is the blank control, and 3 parts are the test group, and set aside.

[0021] 2. Take 20g of oil from the perilla seed oil of the three test groups, add 0.1g, 0.4g and 0.7g of rosmarinic acid to it, put it in a water bath at 50°C, and dissolve it while heating and stirring. After the rosmarinic acid is fully dissolved, it is added back to the spare perilla seed oil respectively, that is, the concentrations are 0.1 g / kg, 0.4 g / kg and 0.7 g / kg.

[0022] 3. Divide the perilla seed oil into brown bottles and seal them tightly. Then place it under the temperature condition of 4°C (refrigerated storage), and keep away from light.

[0023] 4. Detect changes in the acid value and peroxide value of perilla seed oil at a fixed time every month. For the determination of acid value, refer to GB / T 5009.37 for the determination of peroxide value.

[0024] 5. The above experimental results are as follows...

Abstract

The invention relates to a storage method of perilla seed oil, and belongs to the technical field of grease preservation in the field of grease chemical engineering. The storage method has the advantages that a natural antioxidant, such as rosmarinic acid, is used for replacing the non-natural antioxidants in the prior art, so that the antioxidizing property of the perilla seed oil is improved, and the anti-inflammatory, antibacterial, antivirus, antitumor and other functions are greatly improved; the perilla seed oil is stored under the closed, light-shielding and low-temperature conditions,so that the reliability is higher; the perilla seed oil stored by the method can avoid carrying any injury to the health of a human body, the warranty period can be extended from six months to 30 months at normal temperature, and the application area of the perilla seed oil is greatly expanded.

Description

technical field [0001] The invention relates to a method for storing perilla seed oil, which belongs to the technical field of oil preservation in the field of oleochemical industry. Background technique [0002] Perilla seeds are rich in unsaturated fatty acids, reaching more than 90%, of which α-linolenic acid is as high as more than 60%. α-linolenic acid is an essential fatty acid and an important life factor for the human body. As the precursor of EPA and DHA, it has the functions of lowering blood fat, lowering blood pressure, antithrombotic, enhancing intelligence, improving memory, protecting eyesight, and improving sleep. It also has the functions of inhibiting allergic and inflammatory reactions and preventing cancer. Long-term use of perilla seed oil has significant preventive and therapeutic effects on various heart and brain related diseases. However, since the fatty acids contained in perilla seed oil are almost all unsaturated fatty acids, they are easily oxi...
