Example Embodiment

[0028] The preparation method of the food additive includes the following steps:

[0029] S1: Take the green fruits and chop them, place them in an ultrasonic extraction tank, add 750-800mL water and 50-80mL acetone solution with a concentration of 60%-70%, adjust the pH to 6.5-6.9, seal the extraction tank, start the ultrasonic wave, and wait for the temperature to rise When it reaches 50-60℃, add glycosidase, pectinase, cellulase, β-glucanase, mix well, ultrasonic treatment for 3-5h, get enzymatic hydrolysate, extract enzymatic hydrolysate and filter with 200 mesh silk cloth , To obtain the filtrate, the pH of the filtrate is 5.2-5.6, and then use a rotary evaporator to concentrate, adjust the temperature to 45-55°C, and concentrate to a water content of 50%-70% to obtain a green fruit extract;

[0030] S2: Add fermenting bacteria to the green fruit extract obtained in step S1, and then ferment for 5-7 days in a closed environment at 26-28°C to obtain green fruit extract;

Abstract

The invention discloses a food additive and belongs to the technical field of the food industry. The food additive comprises raw materials as follows: a Chinese olive extract, a dragon fruit anthocyanin extract, glycosidase, pectinase, cellulase, beta-glucanase, amylase, starch, maltodextrin, acetic acid, butyric acid, dodecyl ester acid and fermentation florae. The food additive is prepared through steps of Chinese olive extraction, dragon fruit extraction, mixing, drying and the like. Chinese olive effective ingredients extracted with the method are high, contain rich substances such as polyphenols and flavonoids and have high antibacterial, anti-corrosion and antioxidant capacity, the dragon fruit anthocyanin extract is added to the food additive, as anthocyanin belongs to flavonoids, the total flavonoid content of the food additive is further increased, and the free radical scavenging capacity and the antioxidant capacity of the food additive are improved.

Description

technical field [0001] The invention belongs to the technical field of food industry, and in particular relates to a food additive and a preparation method thereof. Background technique [0002] According to the provisions of my country's Food Sanitation Law (1995), food additives are artificial or natural substances added to food to improve the quality of food color, aroma, and taste, as well as to meet the needs of antisepsis and processing technology. [0003] Qingguo has a more detailed record in "Compendium of Materia Medica" "Although this fruit is ripe, its color is also green, so it is commonly called Qingguo", which is a commonly used medicine for clearing away heat and relieving throat. Table "records, green fruit contains compounds such as protein, fat and vitamin. In 1979, the Ministry of Health of the People's Republic of my country announced it as the first batch of "dual-use medicine and food" resources in China. After the 1980s, green fruits were processed ...
