The protein content of butterfly pea is 21.34 g/100 g, which is higher than the protein content of general crops; it contains 17 kinds of amino acids, the total amount of amino acids is 19.40 g/100 g, and the total amount of essential amino acids is 6.77 g/100 g. The total amount of effective amino acids is 12.03 g/100 g, the SRC value of the essential amino acid ratio coefficient is 69.95, and the protein amino acid has a complete variety and rich content, which has good edible and medicinal value.
Take 1 000g of dried butterfly pea flower, moisten it with a small amount of water, put it into a microwave extraction container, use a frequency conversion microwave extraction device to extract, end the procedure when the oil volume no longer increases, and take out the upper layer of clean oil in the collector after standing still. Anhydrous sodium sulfur sulfate was added for dehydration for 12 h to obtain the absolute oil of butterfly pea flower extracted by microwave solvent-free extraction.
A total of 59 volatile components were identified in the butterfly pea flower absolute oil obtained by microwave solvent-free extraction, among which pentadecane, hexadecane, heptadecane, octadecane, nonadecane, eicosane, Alkanes such as pristane and esters such as ethyl palmitate, ethyl linoleate, ethyl linolenate, and ethyl stearate are the main ones. Others with high content include phyton, 2-acetylfuran, and pyridine , 2,3,5-trimethylpyrazine and other ketones and heterocyclic compounds. The above alkanes naturally exist in tobacco leaves and mainstream smoke, and are important aroma components produced after burning cigarettes; ethyl palmitate, ethyl linoleate and ethyl linolenate can soften the smoke and increase the fullness of the smoke; Ethyl fatty acid can increase the sweetness of smoke and make the smoke pure and full; phyton is the precursor of tobacco aroma substances, and is one of the important sources of aroma in tobacco and smoke; 2-acetylfuran, 2, Heterocyclic compounds such as 3,5-trimethylpyrazine and pyridine are important latent aroma substances of tobacco, and their degradation products after combustion have a pleasant characteristic aroma, which makes an important contribution to the aroma of cigarettes. Other identified alcohols, acids, aldehydes and terpenes are also important substances that constitute the flavor of cigarettes. Although the relative content is not high, they also have a relatively important effect on tobacco smoking. Alcohols and acids It does not have a particularly obvious direct effect on the aroma of the smoke, but it can adjust the pH of the tobacco, make the taste mellow, and increase the concentration of the smoke, thereby directly affecting the aroma of the smoke and playing an important balance in the smoke Aldehydes and terpenes add fruity and floral aromas to the smoke, making the tobacco aroma rich and elegant. For example, caproic acid can reduce the irritation of cigarettes and make the smoke mellow; caprylic acid can soften the smoke and make the smoke softer. The aroma is delicate and long-lasting; benzyl alcohol and phenylethyl alcohol provide elegant rose fragrance and honey-sweet notes to the aroma of cigarettes; phenylacetaldehyde adds nutty aromas such as almonds to the aroma of cigarettes; limonene can provide fruity flavors, making the aroma of cigarettes fresh and natural , increase suction comfort.
Butterfly Pea Flower Absolute can be coordinated with the aroma of tobacco, and has obvious improvements in increasing the aroma of tobacco, reducing thorns and removing impurities, alcohol and smoke, increasing the characteristics of fragrance, and enhancing the texture of aroma. 1% Butterfly Pea Flower Absolute Oil has the best effect when the dosage is 0.08%. It can increase the amount of aroma, significantly increase the sweetness, reduce irritation, improve aftertaste, make the aroma plump and round, the texture is delicate and soft, and significantly improve the quality of smoking.
Butterfly pea flower has in-depth development value in the tobacco flavor and fragrance industry. The fragrance developed by it can be used as a natural flavor raw material for cigarette flavoring, which can increase the aroma of cigarettes, enhance the aroma quality, significantly increase the fragrance characteristics and sweetness, reduce thorns and remove impurities, To improve the aftertaste and significantly improve the smoking quality of cigarettes, the optimal dosage is 0.0006% to 0.0008%.
