Description

A kind of strong antioxidant walnut oil soft capsule and preparation method thereof

technical field

The invention belongs to the technical field of preparation of health care products, and in particular relates to a strong antioxidant walnut oil soft capsule and a preparation method thereof.

Background technique

Walnuts are rich in calcium, phosphorus and other trace elements and minerals, and are a nutritious health food. Walnuts contain a large amount of walnut oil, accounting for about half of the total mass of walnut kernels. The linoleic acid and linolenic acid contained in it have good effects on reducing blood lipids and preventing coronary arteriosclerosis. With the continuous development of modern science, walnuts Oil production is increasing year by year, of which walnut oil for culinary purposes is the most common.

Soft capsules are capsules in which liquid medicine or liquid medicine is sealed in a soft capsule material after appropriate treatment. In recent years, soft capsule products of walnut oil have gradually appeared on the market, which are convenient to carry, transport and eat. However, because walnut oil is rich in unsaturated fatty acids, it is very prone to oxidative deterioration in the process of processing and storage, which is not conducive to the long-term preservation of walnut oil health products. Therefore, it is necessary to develop a strong antioxidant Walnut Oil Softgels.
