What is the use of konjac in food?
May 22, 2024
At present, there are more than 260 species of konjac worldwide, and different species exhibit variations in growth habits and cultivation method. In China alone, over 30 species of konjac are known, including 13 endemic varieties.
Konjac offers numerous health benefits. First, its main component, konjac glucomannan (KGM), is a type of edible plant fiber that is low in calories and possesses various unique properties. It can induce a sense of satiety, aiding in weight loss without the need for strict dieting. You can eat keto konjac rice and pasta konjac shirataki. Second, it can absorb cholesterol, promote its excretion, influence bile secretion, prevent cholesterol absorption, and interfere with the metabolism of cancer cells, thereby detoxifying the body and preventing various types of cancer. Third, the calcium in konjac is easily absorbed, making it an effective source of dietary calcium.
In recent years, with advancements in food processing technology and a deeper understanding of the unique properties and functions of konjac, its applications in the food industry have become increasingly widespread.
Application in the noodles, vermicelli
Konjac flour enhances the processing performance of noodles, preventing them from sticking together during cutting and drying. It also ensures that the dough does not clump during cooking, resulting in noodles with a uniform texture, smooth surface, and excellent chewiness. Additionally, shirataki magic noodles are resistant to overcooking and do not become mushy. When used in vermicelli production, konjac flour yields a product that is white in color, resistant to overcooking, and maintains its integrity without breaking apart. The resulting vermicelli di konjac has a delicate, pliable texture and is highly resistant to spoilage during storage and transportation.
Application in ice cream:
Konjac powder increases the viscosity of ice cream mixtures, preventing the formation of coarse sugar crystals. This results in a product with a smooth, creamy texture and stable form.
Application in beverage:
Konjac fine powder has excellent thickening properties and remains stable under acidic conditions. This makes it ideal for use in fruit-based beverages, where it enhances the viscosity of juices and pulp, suspends and stabilizes fruit particles, and improves the overall quality of the drink. Like mango konjac jelly and konjac shuang snack.
Application in confectionery:
Konjac flour is valued for its strong gel-forming ability, high elasticity, and transparency. It is free of particles, easy to demold, and its gel formation is not significantly affected by minor variations in preparation. This makes it a convenient and cost-effective ingredient for confectionery production.
Application in the preservation of fruits and vegetables：
When Wenzhou mandarin oranges were treated with a solution of konjac glucomannan and metribuzin, and stored at room temperature in a ventilated environment, it was found that the konjac glucomannan solution extended the storage period of the citrus fruits. Additionally, the appearance, color, and nutrient content of the fruits were better preserved.
