Perilla Seed Oil
Perilla oil is a kind of vegetable oil extracted from perilla seeds. It is rich in omega-3 fatty acids (ALA), omega-6 fatty acids, and omega-9 fatty acids, as well as rich in antioxidants and vitamin E. In Asia, perilla seed oil is widely used for cooking and medicinal purposes, especially in Japan, where it is used as a seasoning. It has a fragrant aroma and a mild taste, making it suitable for use in salads, mixed rice dishes, and stir-fry dishes. In addition, perilla seed oil has some medicinal value. For example, it can help relieve allergy symptoms, reduce cholesterol, and prevent diabetes. In general, perilla seed oil is a healthy and delicious vegetable oil that is a good choice for chefs who want to try different flavors and people who are health-conscious.
The Bioactivity of Perilla Seed Oil
Perilla seed oil is a pale yellow oily liquid with high transparency and no irritating odor. It is rich in nutrients, including oleic acid, linoleic acid, alpha-linolenic acid, gamma-tocopherol, and other substances. The oil content of dried perilla seeds can reach more than 40%, and there are significant regional differences in their oil content, but it is generally between 24% and 50%. The content of unsaturated fatty acids in perilla oil can be between 91.1% and 93.8%, with polyunsaturated fatty acids between 70.7% and 83.4%. The content of palmitic acid, sulfuric acid, sulfurous acid, and linoleic acid are 5.1%-70%, 9.6%-20.8%, 9.5%-14.4%, and 0.9%-58.8%, respectively. Among them, alpha-linolenic acid is the main component, accounting for 55%-65%. This level of content is the highest among existing plant seed oils.
Perilla seed oil is a dietary supplement that is gaining attention due to its potential health benefits. Perilla seed oil has been shown to possess various biological activities that contribute to its beneficial effects on human health. One of the main components of the perilla seed oil is alpha-linolenic acid (ALA), which is an essential omega-3 fatty acid that cannot be produced by the human body. ALA has been found to exhibit several biological activities, including anti-inflammatory and neuroprotective effects. These effects are attributed to the ability of ALA to modulate various signaling pathways and gene expressions.
In addition to ALA, the perilla seed oil is also rich in other bioactive compounds, such as rosmarinic acid and luteolin. Rosmarinic acid is a potent antioxidant and has been found to exhibit anti-inflammatory and antiallergic effects by inhibiting the production of inflammatory cytokines. Luteolin has been shown to possess anticancer, anti-inflammatory, and neuroprotective effects by modulating various signaling pathways. Various studies have investigated the potential health benefits of perilla seed oil. For example, studies have demonstrated that perilla seed oil supplementation can reduce the risk of cardiovascular diseases by lowering blood pressure and improving lipid profiles. Furthermore, perilla seed oil has been found to possess antidiabetic effects by improving insulin sensitivity and glucose metabolism.
Perilla seed oil possesses various biological activities that contribute to its potential health benefits. Its rich content of ALA, rosmarinic acid, and luteolin may underlie its anti-inflammatory, antioxidant, and neuroprotective effects. These results suggest that perilla seed oil may be a promising dietary supplement that can improve human health and reduce the risk of various chronic diseases.
Hyperlipidemia (HLP) is a disease that leads to significantly elevated levels of lipids in the blood due to metabolic or operational abnormalities in the body's fat. It is characterized by three highs and one low: high levels of triglycerides (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and low levels of high-density lipoprotein cholesterol (HDL-C). According to World Health Organization surveys, HLP is a key factor among the various contributory factors to cardiovascular diseases. In 2020, the number of people with blood lipid disorders worldwide reached about 78 million, with 1/6, or around 13 million in China alone. The presence of hyperlipidemia increases the risk of cardiovascular diseases. In China, the number of people with blood lipid disorders has exceeded 160 million, and the number of cases of diseases caused by HLP, such as diabetes, cerebral infarction, stroke, myocardial infarction, is increasing year by year. The disability rate and the mortality rate are also increasing every year. Therefore, it is imperative to find effective methods and measures to prevent and control HLP, reduce the possibility of cardiovascular and cerebrovascular diseases, and improve people's survival rates and quality of life.
Expanding the Applications of Perilla Seed Oil
The main reason for making perilla seed oil into perilla seed oil powder is for convenience and extended shelf life. Perilla seed oil is a type of edible oil that is prone to oxidation and can easily be affected by factors such as light, heat, and oxygen, leading to a decrease in quality. By converting perilla seed oil into a powder form, its surface area exposed to air can be greatly reduced, slowing down the rate of oxidation and extending its shelf life. In addition, using perilla seed oil powder is more convenient, avoids waste and portability issues when using liquid oil, and allows for more accurate control of food ingredient ratios and taste.
HSF Biotech Company utilized Arabic gum and maltodextrin as wall materials, perilla seed oil as the core material, and prepared perilla seed oil microcapsules using the spray drying method. The obtained microcapsule powder is light yellow and tasteless, with good solubility. HSF Biotech Perilla Seed Oil Powder is a regular sphere and is distributed uniformly. Oxidation stability and heat stability tests have shown that the microencapsulation technology can greatly improve the antioxidant and thermal stability of perilla seed oil, significantly improving its stability and ensuring it remains stable during storage and transportation.
