A kind of preparation method of brown alga-pumpkin vinegar drink rich in vitamin D

Abstract

The invention discloses a preparing method for a brown alga and pumpkin vinegar beverage rich in vitamin D. The preparing process comprises the following steps that firstly, pumpkin juice, a smashed brown alga solution and an acetic acid bacteria culture solution are prepared; secondly, active dry yeast is inoculated into the pumpkin juice for alcoholic fermentation; thirdly, filtering is carried out to remove alcohol dregs; fourthly, the smashed brown alga solution accounting for one tenth to one ninth the volume of the clear wine solution is mixed; fifthly, acetic acid bacteria are used for carring out acetic fermentation to prepare pumpkin crude vinegar; sixthly, mixing is carried out; seventhly, filtration sterilization is carried out; eighthly, filling is carried out. In the preparing process of the healthcare vinegar, the mixed acetic acid bacteria (acetic acid bacteria AS1.41 and Gluconacetobacter hansenii, ATCC 23769), the brown alga raw material and the intermittent stirring and fermenting method are used, the content of vitamin D in the prepared vinegar is high, about 4.5 micrograms of vitamin D can be supplemented in 500 mL of the vinegar beverage, and the vinegar beverage has a fain scent and unique flavor and is a good bone substance healthcare beverage.

Description

technical field [0001] The invention belongs to the field of beverage processing, and relates to a preparation method of brown algae-pumpkin vinegar drink rich in vitamin D. Background technique [0002] Vitamin D is a fat-soluble vitamin with five family members, the most important of which is vitamin D for human health 2 (ergocalciferol) and vitamin D 3 (cholecalciferol). Vitamin D promotes the intestinal absorption of calcium, maintains the blood calcium concentration, and is an important nutrient for bone health. Vitamin D deficiency severely affects bone development during growth, leading to soft, deformed bones, osteoporosis, and affects bone growth and bone remodeling. [0003] Vitamin D is a derivative of provitamin D after ultraviolet irradiation. Vitamin D stored under the skin of the human body after exposure to sunlight 3 Original can be converted into vitamin D 3 . Proper sunbathing is enough to meet the body's need for vitamin D. But because of the curr...

Problems solved by technology

[0006] Studies have shown that vinegar can improve bone calcification. The reason is that acetic acid can increase the content of soluble calcium in the small intestine, leading to enhanced passive absorption of calcium, but the passive absorption efficiency is much lower than the active absorption of calcium caused by vitamin D.

Since vitamin D is fat-soluble and extremely unstable in acidic conditions, there has been no report of vitamin D in vinegar so far.
