1, yacon polysaccharide can reduce blood sugar and blood fat: yacon polysaccharide can reduce postprandial blood sugar in mice, enhance glucose tolerance in diabetic mice, inhibit the increase of blood fat in mice fed with high-fat diet, prevent hyperlipidemia to some extent, and reduce the damage of cholesterol to the liver while reducing blood fat. It has certain protective effect on kidney and spleen of diabetic mice.
2. Anti-oxidation: The scavenging effect of DPPD on free radicals proves that yacon leaf extract has anti-oxidation effect. In a certain range, the scavenging ability of free radicals is directly proportional to the concentration of yacon extract.
3. Bacteriostasis: The effective components of yacon have certain inhibitory effects on Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli and Malassezia. ?
4. Yacon can be made into beverage, preserved fruit, fruit wine, jam, milk powder, etc. Fermented milk was made from Lactobacillus bulgaricus and Streptococcus thermophilus, which promoted gastrointestinal peristalsis and helped digestion.

5. Yacon is rich in vitamin E, which can resist oxidation and play the role of beauty beauty.
Extended data:
The content of fructooligosaccharides in yacon is 60-70% of dry matter, which is the highest among all plants. It is also rich in minerals and trace elements such as calcium, magnesium, iron, zinc, potassium and selenium. Japanese research also found that taking 3-6g fructooligosaccharides every day can reduce the content of toxic carcinogens in human feces by more than 40% within 3 weeks.
Fructooligosaccharides have the following functions: promoting digestion and regulating gastrointestinal tract; It is a growth promoter of intestinal beneficial bacteria and produces bifidus factors; Regulate blood, remove hyperlipidemia, and effectively control cholesterol and diabetes; Relieve, prevent and treat diarrhea; Reduce pathogenic fire, remove toxic substances, and prevent and treat facial blisters and acne; The effect of improving immunity.
It should be noted that yacon contains a chemical component, namely tannic acid, also known as tannin. Yacon will turn brown when exposed to air after it is cut and peeled. The reason for discoloration is that due to oxidation, quinone polymers produced by phenols in tannins form brown pigments, that is, melanin. In order to prevent discoloration, peeled and cut yacon can be soaked in clear water to isolate the air and prevent oxidation discoloration.
