Importancia de los aromas en la industria alimentaria

Introducción

With the rapid development of the food industry, people have put forward higher requirements for the flavor, taste and overall sensory experience of food. In this process, flavors, as an important food additive, have played an irreplaceable role in improving food flavor, enhancing appetite, extending food shelf life and enriching food culture. Flavors can not only make up for the natural aroma lost in food processing, but also give food a more diversified taste experience, thereby meeting the needs of different consumers. This article will discuss in depth the important role of flavors in the food industry.

I. Improving food flavor

The flavor of food is mainly composed of its aroma and taste, and aroma plays a key role in the attractiveness of food. During food processing, the natural aroma of many raw materials themselves may be lost due to factors such as high temperature, low temperature, oxidation, etc., resulting in a weakened flavor of the final product. At this time, the addition of flavors can effectively compensate or enhance the original flavor of the food, making it more attractive.

1. Restore aroma lost during processing*
In the food industry, processing methods such as baking, frying, and high-temperature sterilization often destroy the natural aroma of food. For example, after pasteurization, the unique milky aroma of milk may be weakened, but by adding frankincense, the milky aroma can be restored or enhanced, making the product more attractive. Similarly, in the production of fruit juice drinks, some fruity substances are easily lost during the concentration or dilution process. The use of fruit flavors can make the product closer to the flavor of fresh juice.

2. Improve the taste of low-flavor or no-flavor foods
Some foods have a light flavor or no obvious aroma, such as soy protein, plant-based foods, etc. By adding corresponding flavors, these foods can have a taste closer to natural meat or other foods, thereby improving their acceptability. For example, meat flavors are often used in vegetarian products to make them closer to the flavor of real meat, meeting the needs of vegetarians and environmentally friendly consumers.

3. Create a unique flavor experience
Flavors can also help food manufacturers develop products with innovative flavors. For example, some specialty beverages use special floral, tea or fruity aromas to distinguish them from traditional products and form brand uniqueness. In recent years, popular “mixed flavor” foods, such as “blueberry cheesecake flavored ice cream” or “mango coconut flavored drinks”, are all successful applications of flavor technology in the food industry.

2. Enhance appetite

People’s preference for food is largely influenced by their sense of smell and taste, and flavors can increase appetite by enhancing the aroma of food.

1. Stimulate the brain’s sense of pleasure
The aroma of food can stimulate the brain to release dopamine and make people feel happy. For example, the rich wheat aroma of freshly baked bread or the meaty aroma of frying steak can greatly increase people’s appetite. Flavors play a key role in this process, which can enhance or reproduce these mouth-watering smells, so that food can induce people’s desire to eat even in the packaged state.

2. Enhance the sensory appeal of food
In the modern food industry, many ready-to-eat foods and pre-prepared foods rely on flavors to enhance their sensory appeal. For example, instant noodles usually add meat flavors to make the soup base more tempting, while snacks such as potato chips and puffed foods use flavors such as cheese, barbecue, and barbecue to enhance the layering of flavors and give consumers a stronger sense of satisfaction when tasting.

3. Adapt to the taste needs of different groups of people
People of different ages, regions, and cultural backgrounds have different preferences for food flavors. For example, the elderly may prefer foods with strong flavors due to their weakened sense of taste, while children tend to accept sweet fruity or milky flavors. Food companies can use flavors to adjust the aroma of food to meet the needs of different groups and thus expand the market.

3. Help preserve food

In addition to giving food a delicious flavor, flavors can also play an important role in preserving food and extending its shelf life.

1. Masking odors in processed foods
Many processed foods may produce certain odors during storage or transportation, such as oxidation, fishy smell, or plastic packaging smell. By adding appropriate flavors, these unpleasant odors can be effectively masked, allowing the food to maintain a better flavor. For example, fish products may have a fishy smell. A proper amount of lemon essence or other blending essences can reduce the impact of the fishy smell and improve the overall taste of the food.

2. Reduce dependence on food preservatives
Some essences themselves have antibacterial and antioxidant effects, such as citrus essences, rosemary essences, etc., which contain natural antioxidant ingredients, which can delay food oxidation to a certain extent and increase the shelf life of food. In addition, some spices such as cinnamon, cloves and other natural essences have a certain preservative effect, which can be used to reduce the use of chemical preservatives and improve the natural properties of food.

3. Help food keep freshness
The use of essences can also make up for the quality decline caused by the loss of aroma after long-term storage. For example, frozen food may lose some of its original flavor during storage. Adding a proper amount of essence can restore its proper taste after thawing, so that consumers can get a closer experience to fresh food.

4. Enrich food culture

Flavor is not only a tool to enhance the flavor of food, it also has a profound impact on the dissemination and development of food culture.

1. Reproduce the flavor of traditional food
The flavor of many traditional foods relies on specific aroma components, such as the sweet-scented osmanthus fragrance of Chinese pastries and the vanilla flavor of French desserts. In the modern food industry, flavors can help restore these classic flavors and enable traditional foods to spread in a wider market. For example, some modern food brands use jasmine flavors or oolong tea flavors to create the flavor experience of Chinese tea culture.

2. Promote international food culture exchanges
Due to the development of flavor technology, food flavors from different countries and regions can be more easily replicated and spread. For example, matcha-flavored ice cream, which is popular in the Asian market, is also popular in the European and American markets, while Western caramel and hazelnut flavors are gradually being used in Asian beverages and baked goods. This globalization of flavors promotes the exchange of food culture, allowing people around the world to experience the food characteristics of different regions.

3. Promote food innovation and diversification
Modern consumers are increasingly pursuing personalized and novel food experiences. The advancement of flavor technology enables food manufacturers to continuously launch innovative products, such as flower and fruit flavored drinks and mixed flavor snacks. The emergence of these novel flavors has enriched the choices of the food market and promoted the continuous development of the food industry.

It not only enhances the flavor of food and increases appetite, but also helps to extend the shelf life of food, while promoting the development and dissemination of food culture.
