[0004] At present, nicotinic acid is mostly synthesized or extracted from plants, and the method of extracting nicotinic acid from animals has not been reported yet; beef tripe is crisp and delicious, rich in nutrition, and belly collar and At the same time, tripe also contains a relatively large amount of niacin. The nutrient content of tripe is shown in Table 1:

Abstract

The invention belongs to the technical field of nicotinic acid extraction, and particularly relates to a method for extracting nicotinic acid from beef tripe. The method includes the following steps:microwave treatment, high-voltage pulsed electric field treatment, and supercritical carbon dioxide extraction. The method provided by the invention has the characteristics of a high extraction rate,short extraction time, stable product quality and few process steps, avoids the use of expensive equipment and the use of nanofiltration and ultrafiltration membranes, and has low separation requirements.

Description

technical field [0001] The invention belongs to the technical field of nicotinic acid extraction, and in particular relates to a method for extracting nicotinic acid from tripe. Background technique [0002] Niacin is white or off-white powder, commonly known as nicotinic acid, vitamin PP or vitamin B3, and its molecular formula is C6H5NO2. It is a kind of pyridine-3-carboxylic acid derivatives with nicotinic acid activity. can sublimate. Because its molecular structure has the representative structure of the vitamin B family, and its physical and chemical properties also have certain characteristics shared by the vitamin B family, such as anti-"3D" disease, dilating blood vessels and other medical effects. Niacin is also known as the anti-pethiasis factor in some medical works. Niacin is insensitive to light, heat, humidity, redox, etc., and slightly sensitive to heavy metal ions. Its stability can also be guaranteed under alkaline conditions. However, due to structural...
