What is Pullulan?

Pullulan is a sort of extracellular water-soluble mucopolysaccharide similar to dextran as well as additionally xanthan gum tissue generated by the fermentation of Aureobasidium pullulans, likewise called pullulan and pullulan, the English name is Pullu-lan, Equated as Pululan. It was developed in 1938 by R. An unique microbial polysaccharide revealed by Bauer. The polysaccharide is mostly composed of maltotriose linked by α-1,6 glycosidic bonds. The molecular weight is commonly in between 4.8 x10 and also 2.2 x10 (the standard molecular weight of industrial pullulan is 2×105. It is made up of concerning 480 maltotriose). The polysaccharide has a special structure and also buildings, as well as likewise is flexible in structure and likewise relatively massive in solubility. Pullulan has strong film-forming houses, gas obstacle residential or commercial properties, plasticity, in addition to viscosity, in addition to has excellent attributes such as being conveniently soluble in water, safe, safe, anemic, as well as likewise odorless. Wide application potential customers. Because it can be worn away along with utilized by bacteria in nature, it will certainly not trigger environmental pollution, so it is described as pollution-free plastic. On May 19, 2006, the Ministry of Health and wellness released the No. 8 Statement. Pullulan is among the four new artificial additive products. It can be made use of in pleasant, tasty chocolate surface, movie, compound seasonings as well as additionally fruit and vegetable juice drinks. Utilized as a layer rep as well as likewise thickener.

Pullulan Uses

Pullulan polysaccharide has been widely made use of in medicine, food, light industry as well as chemical sector. Pullulan polysaccharide is among the 4 new food additive products. It can be utilized in sweet, delicious chocolate finish, diaphragm, substance seasoning as well as vegetables and fruit juice drink Utilized as a covering representative and also thickener. Pullulan aqueous option has a smooth and rejuvenating feeling, and also has the qualities of enhancing the preference, so it can be utilized as a food top quality improver and also thickener. Including a small amount of pullulan throughout food processing can dramatically improve food high quality. As an example, fish cakes can improve the preference as well as quality; including a percentage of pullulan when making tofu can preserve the aroma of soybeans and also streamline the procedure; soy sauce. Including a small amount of pullulan to spices, pickles, sweet fish as well as shrimp, and also delicious food can maintain its thickness, raise its stickiness and make its preference smoother.

The Food Industry Urgently Needs Expansion - Pullulan

Capsule application
Capsules are a conventional dosage form of medicines, and the quality of capsules directly affects the performance of medicines. Traditional capsules are made of gelatin, glycerin and water, and are widely used because of their low price. However, gelatin is not used in many types of medicines due to its shortcomings such as easy water loss hardening, water absorption softening, and cross-linking and curing. It is suitable for adoption, so plant capsules based on hydroxypropyl methylcellulose and microbial polysaccharide capsules based on pullulan came into being with stronger applicability. The oxygen transmission rate of pullulan is hydroxypropyl methylcellulose. 1/300 of methyl cellulose capsules, 1/8 of gelatin capsules, which can well protect the contents of capsules from oxidation. In the selection of high-quality capsule wall materials, pullulan can be said to be “unmatched right”.

Fruit and vegetable preservation
The film-forming property of pullulan is very prominent, and it is very easy to form a tough film, and the film has low permeability, which can effectively isolate the exchange of gas and water molecules, thus playing the role of freshness preservation. The fresh-keeping effect of pullulan is related to the molecular weight, the larger the molecular weight, the more stable the formed film. The storage period of fruits and vegetables treated with high-molecular-weight pullulan has been greatly improved. Some studies have pointed out that after apples are treated with 200,000-molecular-weight pullulan, the water retention rate is still above 99% after 2 months. The fresh-keeping mechanism of pullulan is slightly different from that of chitosan, and chitosan has more antibacterial pathways. Therefore, the combined use of pullulan and chitosan can maximize the improvement of the freshness of fruits and vegetables. freshness.

Edible film
Under the dual pressure of environmental degradation and resource scarcity, the enthusiasm for developing environmentally friendly products continues to rise. Pullulan polysaccharide has good film-forming properties, and it can form a film without the assistance of other substances. Because the edible film made of pullulan polysaccharide has poor permeability, it can protect the contents well and increase the shelf life. Lulan polysaccharide is easy to degrade in the environment, and has outstanding advantages in the development of edible films, known as “edible plastics”.

Food processing
Compared with common microbial polysaccharides such as xanthan gum and gellan gum, the application of pullulan in food processing has not been widely developed. The former Ministry of Health listed pullulan as a new food additive product in 2006 One of them is currently only used in a limited range of seasonings, fruit and vegetable juice drinks, and protein solid drinks.

In fact, pullulan polysaccharide has shown good application advantages in many fields such as meat products, rice and flour products, and my country, as a large agricultural country, has abundant corn as the raw material of pullulan polysaccharide, and its application in the food industry will be promising .

The Production Method of Pullulan Polysaccharide

A fermentation method for producing pullulan, characterized in that the implementation steps are as follows:

(1) prepare seed culture medium;

(2) preparing the initial medium for fermentation;

(3) Insert the liquid seeds into the fermentation medium, the inoculum size is 3-8%, the fermentation stirring speed is 200-500rpm, the fermentation temperature is 29°C±1°C, the ventilation rate is 0.5-10V/V, and the tank The pressure is 0.01-0.02MPa;

(4) Add another carbon source after 24 hours of fermentation, the feeding amount is 40-80g/L, and the feeding liquid is sucrose solution, glucose solution or starch hydrolyzate with a DE value of 40-60; After adding carbon source, continue to ferment for 60-72 hours;

(5) The above fermented liquid is conventionally flocculated, ultrafiltered, membrane separated, concentrated, and dried to obtain pullulan with a molecular weight of 200,000-600,000 Daltons.

The process of the present invention is simple and the effect is remarkable. Compared with the previous fermentation process using only sugar, the fermentation time is significantly shortened, and the fermentation time is 80-100 hours, which effectively improves production efficiency and saves energy. The product yield is greatly improved, and the yield can reach above 50.
