Heat Stable Flavors

Heat Stable Flavors:

High temperature resistance is very important in the case of flavors in products that use high process temperatures in their production process.Because the lack of stability at high temperatures leads to the decomposition of volatile compounds such as aldehyde, ketone, furan, etc., and at the end of the process, we will face a severe loss of taste.This feature plays an important role in maintaining the final quality of the food product, and choosing the best suitable flavoring can have a significant impact on the taste and aroma of cooked or processed products.

Heat stability of flavors

Main components: Essential oils include volatile compounds such as terpenes, esters, alcohols and ketones.Many of these compounds are sensitive to heat and may decompose or change at high temperatures.
Decomposition temperature: Most flavors are stable up to a temperature of about 40-60 degrees Celsius.At higher temperatures, the main compounds may be broken down or new compounds may be formed, which can change the smell and properties of flavors.

Factors Affecting Heat Stability:

Chemical Composition: Certain compounds like alcohols, phenols, and esters tend to be more heat-resistant, whereas terpenes and volatile esters are more sensitive to heat.
Extraction and production method: Flavors extracted through steam distillation usually have a greater ability to maintain their properties at high temperatures.
Carrier Materials: Mixing flavors with stable carriers such as fats, sugars, or starches can improve their resistance to heat during application production.
Storage and processing temperature: It is often recommended that flavors be stored at low temperatures and in dry and dark environments to prevent thermal degradation and oxidation.

Examples of Heat Stable Flavors:

Vanilla:
- Vanilla, especially vanillin (the main ingredient in vanilla extract), has relatively good resistance and is widely used in baking all kinds of sweets and desserts.
Cinnamon:
- The main compounds of cinnamon, such as cinnamaldehyde, remain stable in the process of cooking and preparing hot foods.
Ginger:
- Dried ginger or its extract, such as gingerol, well resists in heat processes .
Cloves:
- Eugenol, the main compound in cloves, is resistant to heat and is used in cooking processes .
Cardamom:
- Cardamom flavor is also stable at high temperatures due to its resistant compounds such as Cineole and is widely used in preparing hot foods such as tea and coffee.

Maintenance recommendations to increase heat resistance

Storage in a cool and dry place: reducing the temperature and humidity of the environment can prevent the thermal decomposition of essential oils.

Use of protective containers: Dark or frosted glass bottles can prevent sunlight that increases the temperature and decomposes the compounds.

Tightly closing the lid of the container: Preventing flavors from coming into contact with air can prevent oxidation and thermal decomposition.

Applications with Heat stable flavors:

Heat resistant flavors and essential oils have wide applications, especially in industries where there is a need to use aromatic substances in high temperature conditions.The heat stabilities of these flavors is due to their stable chemical compounds that do not decompose at high temperatures and maintain their aromatic and properties.Below are some important uses of these flavlors:

Food and beverage industries

Cooking and confectionery: Heat-resistant flavors are used in baking all kinds of sweets, cakes, bread, and foods that are placed in the oven or on the stove.These flavors can add a desirable taste and aroma to the final product without losing their properties in high temperature.Some of the most commonly used flavors in this field are:
- Vanilla Flavor
- Lemon Flavor
- Cinnamon Flavor
- Almond Flavor
Hot drinks: In the production of hot drinks such as tea, coffee, and hot chocolate, heat-resistant flavors are also used.These flavors are added to drinks without losing their taste and aroma due to their resistance to temperature.

Cosmetics industry

Hair and skin care products: Heat-resistant flavors are used in the production of shampoos, creams, lotions and bath oils that are produced in thermal processes.These products may be exposed to heat at some stage, and heat stability preserve the aroma and natural properties of the essential oil.
Body sprays and deodorants: Some sprays and deodorants are exposed to different temperatures.The use of heat-resistant essences in these products helps their pleasant smell last even in hot environments.

The perfumery industry

Perfumes and colognes: heat-resistant essential oils are used in perfumery, especially for the production of perfumes for hot environments or tropical regions.These essential oils can withstand temperature changes and maintain their fragrance.
Air fresheners: In the production of air fresheners such as sprays, aromatic gels and incense, heat-resistant essential oils are used so that the desired fragrance can spread and last even at high temperatures.

Tobacco and Shisha industry

Tobacco and Shisha: In the production of aromatic tobacco and shisha, heat-resistant flavors are used.These flavors are subjected to direct heat but must retain their aroma and taste during the process.Fruit and spice food flavors are usually used in this industry.

Candle and Oud production industry

Scented candles: In making scented candles, heat-resistant essences are used that can emit a pleasant smell during the burning process of the candle.Essences such as vanilla, cinnamon, and sandalwood are popular in this industry.
Aromatic incenses and Diffusers: In the production of incenses and diffusers, heat-resistant essential oils are also used to release a pleasant aroma in the space by gradually burning.

Pharmaceutical industry

Heat-resistant medicinal products: heat-resistant flavors are used in the production of some drugs and topical creams that require heat for activation.In addition to adding a pleasant smell, these essential oils may also have therapeutic properties.

Detergent products

Detergent and cleaning products: heat-resistant essential oils are used in the production of cleaning products such as laundry and dish detergents.These products may be exposed to heat (such as washing with hot water), so essential oils must be able to retain their scent.

Plastic industry and industrial materials

Scented plastic products: In the production of some plastic products such as scented garbage bags and household plastic products, heat-resistant essences are used to maintain their fragrance even at high temperatures (for example, in the dishwasher).

Essences for industrial products

Essences used in industrial production processes: In some industries, such as the rubber and oil industry, heat-resistant essential oils are used to add odor and improve the working environment.
