The removal of the bitter taste of berberine hydrochloride powder in confectionery can be improved by a range of technological means. Such methods include the use of masking agents, encapsulation techniques, the addition of flavor enhancers, and changes in formulations to reduce bitterness and improve the acceptability of the product. A detailed description is given below.
Use of masking agents
Masking agents are methods to reduce perception by blocking bitter receptors or masking the bitter taste and are applied to most bitter compounds.
- Sweeteners:
Sweeteners such as aspartame, sucralose, and stevioside are effective in masking bitterness and enhancing the taste of candy. Aspartame not only provides sweetness but also reduces the bitter intensity of berberine hydrochloride to some extent.
- Acidulants:
Adding a small amount of acidulants such as citric acid, malic acid or lactic acid can give the candy a slightly sweet and sour taste, masking the bitter flavor. The acidity can neutralize the bitterness to some extent and reduce its prominence.
- Salt flavor masking:
Appropriate addition of trace salt can also weaken the perception of bitter taste to a certain extent, thus improving the palatability of the candy.
Use of embedding technology
The embedding technique is a method to reduce the release of bitter molecules by wrapping berberine hydrochloride powder with special materials. This technique is suitable for bitter substances that are difficult to remove.
- Microencapsulation:
By microencapsulating berberine hydrochloride with polysaccharide, protein or fatty acid materials. This allows for a slow release in the mouth and reduces the chance of direct contact with the taste buds. Encapsulation materials commonly used in microencapsulation technology include gum arabic, gelatin, and starch, which can effectively reduce the bitter taste.
- Lipid embedding:
A lipid matrix can be used to encapsulate berberine hydrochloride bulk to form liposomes or nanoparticles. This can not only reduce the bitter taste, but also improve the stability and bioavailability of berberine hydrochloride.
- Coating:
The surface of berberine hydrochloride powder is coated to make it evenly dispersed inside the candy and reduce its direct contact with taste buds. Coating materials such as edible wax and cellulose can be used to achieve the effect of slow release and bitter taste inhibition.
Adding flavor enhancers
Flavor enhancers can be used to enhance certain specific flavors in confectionery to mask the bitter taste of berberine hydrochloride.
- Natural flavor enhancers:
Fruit flavors such as citrus and berry flavors are effective in masking the bitter taste. The odor of these flavors stimulates the olfactory nerves, which diminishes the perception of bitterness.
- Peppermint and licorice extracts:
Peppermint has a cooling taste that masks the bitter flavor and freshens the candy. Licorice extract not only flavors, but also adds sweetness, which reduces bitterness.
- Milk and Cream Flavors:
Adding milk-based flavorings to a recipe in moderation gives the candy a rich milk or creamy flavor. These flavors can mask the bitterness to some extent and soften the overall flavor.
Changing candy formula
Adjusting the ingredients of candy formulations to change the form of binding of the base to berberine hydrochloride powder can also alleviate its bitterness to a certain extent.
- Increase sweetness:
A balance of sweetness and bitterness is achieved by adding sugars such as glucose, sucrose, and isomaltose. This will lessen the perception of bitterness.
- Use milk-based ingredients:
Milk-based ingredients such as milk powder or whey powder can mitigate bitterness and mellow the taste. The proteins in milk-based ingredients interact with the bitter molecules of berberine hydrochloride and can weaken the bitter taste.
- Fiber ingredients:
The addition of soluble dietary fiber can reduce the bitter taste of berberine hydrochloride by changing the texture of the candy. The use of dietary fiber in confectionery not only improves its taste but also reduces the rate of bitter taste release.
Use of bitter taste inhibitors
Bitterness inhibitors can achieve the effect of removing bitterness by inhibiting the perception of bitterness by taste buds.
- Protein-based inhibitors:
Protein ingredients with bitter taste-inhibiting effects, such as whey protein, can be added to candies. This is combined with berberine hydrochloride to achieve some masking effect.
- Cyclodextrins:
Cyclodextrin is a polysaccharide. It is able to encapsulate bitter molecules and reduce the release of bitter flavors, thus attenuating the bitter taste.
- Metal ions:
Calcium ions can reduce the release of bitter flavor by binding to the berberine hydrochloride molecule and reducing its solubility. Proper amount of Berberine hydrochloride powder should be taken when using so as not to affect the taste of the candy.
Heat treatment and acid-base regulation
Heat treatment and acid-base adjustment can alter the state of berberine hydrochloride in the confectionery matrix, thereby reducing the bitter taste.
- Heat treatment:
Moderate heat treatment of candies during the production process can induce certain structural changes in the bitter molecules of berberine hydrochloride and reduce the bitter taste.
- Adjustment of pH value:
By adding an appropriate amount of alkaline ingredients or acidic ingredients, such as sodium bicarbonate or citric acid, the pH value of the candy can be adjusted, so that the bitter intensity of berberine hydrochloride can be reduced.
Bio-enzyme treatment
Using biological enzymes to treat berberine hydrochloride powder, its bitter components are partially degraded or its structure is changed to achieve the effect of removing bitter flavor.
- Converting enzyme treatment:
The structure of berberine hydrochloride can be changed and its bitter taste can be reduced by using bitter inhibiting enzymes or bitter converting enzymes.
- Food enzymolysis:
Food-grade enzymatic ingredients are added at the pretreatment stage of confectionery production to partially break down or convert the bitter molecules of berberine hydrochloride, thus reducing the intensity of bitter flavor release.
To achieve more desirable removal results, a combination of two or more methods may be used. For example, microcapsule encapsulation combined with sweetener masking, or encapsulation combined with an acidifier, can be more effective in removing the bitter taste.Guanjie Biotech adopts the encapsulation technology to produce berberine hydrochloride microcapsule powder. The appearance of berberine HCL powder is yellow crystalline powder, and the specification is 97%-98%.
