Purple Sweet Potato Extract Powder

 

Purple sweet potato extract powder is made from fresh and high-quality purple sweet potatoes, which are peeled and dried. Purple sweet potato retains all dry matter except the skin: protein, fat, carbohydrates, vitamins, minerals and dietary fiber, etc. It has the functions of lowering blood pressure, enriching blood, and beautifying.

 

Purple sweet potato contains a large amount of anthocyanins, dietary fiber and selenium, the most effective of which is anthocyanins. Anthocyanins have a small molecular structure and are the only protective agents against free radicals that can penetrate the blood-brain barrier.

 

The free radical scavenging ability of anthocyanins in purple sweet potatoes is 20 times that of vitamin C and 50 times that of vitamin E. Purple sweet potato powder is widely used in food pigments, food industry and health care products industry.

1. Antioxidants

Purple sweet potato extract powder contains a large amount of anthocyanins, which not only has antioxidant effects, but also can be anti-inflammatory, anti-radiation, and lower blood pressure.

 

2. Regulate metabolism

 

(1) Glucolipid metabolism:

• By activating the AMPK pathway to increase GLUT4 transport activity, muscle cell glucose uptake is ↑29%.
• Inhibit FASN enzyme activity (IC50=1.2mg/mL) and reduce liver fat regeneration.

 

(2) Intestinal microecology:

• Resistant starch accounts for 18% and promotes the proliferation of Bifidobacteria 3.7 times.
• Bile acid binding capacity is 42% higher than oat beta-glucan.

 

 

3. Minerals

 

(1) Selenium-anthocyanin chelate: Purple sweet potato extract powder increased glutathione peroxidase activity to 2.3 times that of the control group.
(2) Zinc-polyphenol complex: accelerates wound healing. Clinical trials show that epidermal regeneration time is shortened by 28%.

Category	Antioxidant value (ORAC)	Dietary fiber(g)	Glycemic Index (GI)	Active ingredients
Purple sweet potato powder	18,500 μmol TE	8.6	55	Anthocyanins/Se/Zinc
Sweet potato powder	4,200 μmol TE	5.2	70	Beta-carotene/potassium
Potato powder	1,800 μmol TE	3.1	85	Vitamin C/lysine
Tapioca powder	350 μmol TE	1.8	94	Resistant starch/cyanoside derivatives

 

2. Differences in functional characteristics

 

(1)Thermal stability:

The retention rate of purple potato anthocyanins after baking at 120°C is 91%, while the retention rate of sweet potato carotenoids is only 68%.

(2) Processing adaptability:

Purple sweet potato extract powder has a water-holding capacity of 8.3g water/g flour, which can delay starch retrogradation when making pasta.

(3) Allergen risk:

Potato flour contains patatin protein allergen, and the allergy rate of purple potato flour is as low as 0.03%.

 

3. Application scenario innovation

 

(1) Pharmaceutical excipients:

Purple sweet potato nanocellulose is used as a targeted drug delivery carrier, and the drug loading capacity is increased to 2.8 times that of conventional materials.

(2) Smart packaging:

Purple sweet potato extract powder anthocyanin-pH sensitive film monitors food freshness in real time.
