Top 10 Food Flavors and Food Colors


Industrialists use immobilized plant cells for the production of food flavors and colors. Plant cell cultures have unavoidable approach for the production of food flavors, colors, and enhancers. In this article, you can get to know the top 10 food flavors and food colors.

What Are Food Flavors?

According to the US Society of Flavor Chemists, flavor is the material taken into mouth and stimulates one or both sensations of smell and taste.

Food flavors also stimulates the general pain, tactile, and temperature receptors in the mouth. The period of biotechnology has steered with the use of microorganisms for the purpose of developing flavors both for food as well as non-food operations.

What Are Food Colors?

Food color is the substance of which the purpose is to conduct high aesthetic appeal to the foods. Food additives are the substances not typically used as a characteristic component of food. There are four general orders of food complements, such as

  • Nutritive additives
  • Recycling agents
  • Preservatives
  • Sensitive agents

Other typical examples are acidulants, anti-browning agents, anti-caking agents, anti- microbial agents, and antioxidants. Emulsifiers, stabilizers, concrete and crisping agents, flavour enhancers, food colors , and sweeteners are also food additives.

Top 10 food flavors and food colors

Food flavors contain their own nutritional value, newness preservation. They use in industry for sensitive quality enhancement and aids in recycling. Basically, food flavoring and food coloring is an approach that may confine to a catalytically active enzyme or to a cell within a reactor system.

Here is a list of top 10 food flavors and food colors.

1. Esters

This is a food flavor that uses immobilized lipase from the incentive Candida cylindracea. It results in the production of broad range of esters including ethyl-butyrate, isoamyl acetate, and isobutyl acetate. Ethyl-butyrate has a large market demand. Industrialists use a large number of esters for food flavoring. A few esters and their flavors include:

  • Ethyl butrate- Pineapples
  • Ethyl formate- Rum
  • N-octyl acetate- Oranges
  • Methyl butrate- Apples
  • N-amyl butrate- Apricots
  • Methyl salicylate- Oil of wintergreen
  • Linalyl acetate- Lavender, sage
  • N-amyl acetate- Pears, bananas

2. Diacetyl

Diacetyl or biacetyl- butadione is a significant flavour element of cultured buttermilk, sour cream, and cultured butter. It is sometimes an essential component in the so-called brown flavors, such as butterscotch, caramel, and coffee flavors.

Food flavoring from diacetyl may depend on the bioconversion of citrate by Streptocccus diacetylactis and Leuconostoc citrovorum. The conversion takes place through a inducible citric acid permease system. A pH>5.5, temperature between 20-30 °C, aeration and presence of citrate is essential for production of diacetyl.

Diacetyl is the major flavoring substance in shortening, margarine, and many other artificially flavored butter substitutes. Other than its usage in microwave popcorn, potato chips, corn chips and crackers, you can also frequently add it in cookies, chocolate, cocoa-flavored products, candy, gelatin desserts, and flavored syrups. Soft drinks, sauces, chewing gum, and ice cream are other main products.

3. Pyrazines

Cultures of Bacillus subtilis when raised in a media holding sucrose, asparagine, metal ions, ferrous, Mg, Na, K, Mn are known to produce tetramethyl pyrazine. Another constituent of pyrazine is 2-methyl-3 isopropyl pyrazine, produced from Streptococcus lactis, Pseudomonas perolenes, and Streptomyces. It gives bell pepper, earthy, peas, potatoes odor.

These are heterocyclic compounds with a characteristic taste. Pyrazine is responsible for the “roasted-like” flavoring taste of the roasted coffee beans and broiled meat.

4. Lactones

Lactones give fruity, coconut-like, buttery, sweet and nut-like flavor notes which are generally made by chemical conflation from keto acids. They impart the aroma of fruits, butter, cheese, and other foods.

Following organisms yield optically active lactones within 48 hours:

  • Candida
  • Saccharomyces
  • Penicillium notatum
  • Cladosporium butyricum
  • C.suaveolens
  • Sarcina lutea

When incubated, they show with the results of glucose and keto acid.

5. Terpenes

You can add Terpenes in cooking and baking. Even, terpenes pair well with particular foods, which will provide a strengthening bond too. Limonene, such as, is a great terpene to add to tangy and sweet dishes, like, strawberry shortcake, key lime pie, or caesar salad.

 The constituents of Terpenes are:

  • Linalool produced from Ceratocystic variospora and C.moniliformis has rose, flowery, light, sweet, and fresh citrus aroma.
  • Citronellol produced from Ceratocystic variospora having rose, sweet, and slightly bitter aroma.
  • Geranyl acetate from C.coarulescens having a sugary odour.

6. Monosodium glutamate (MSG)

It’s added to ready-to- eat food food but should not exceed. On fermentation, α-glutamic acid is attained and is suspended in water and neutralised with NaOH, decolourised with active watercolor to gain clear liquid which is further concentrated to solidify MSG.

Organisms producing α glutamic acid are:

  • Corynebacterium
  • Brevibacterium
  • Microbacteriumand

Arthrobacter MSG has a certain taste umami, which is the fifth basic taste along with sour, sweet, salty, and bitter. It has a meaty flavor that also refers to the presence of proteins in food.

7. 5 ′ nucleotides

The 5′-nucleotides are important as flavor additive in gravies, soups, bouillons, and other foods. It can be brought about directly by fermentation using Brevibacterium, Bacillus subtilis, and Actinomycetes. Treatment of an enzyme 5 ′ Phosphodiesterase results in the coexisting product of 5 ′-AMP, 5 ′-GMP, 5 ′-CMP, and 5 ′-UMP.

8. Color from the moulds

In Japan, red rice is raised with Monascus purpurens to yield a fusion of six colors (red, yellow and purple painted polypeptides).

 Other composites produced from moulds are:

  • Rubropunctatin & Monascorubin which are red color.
  • Rubropunctamine & Monascorubramine which are purple color.

9. Color from yeasts

Phaffia rhodozyma produced a red color pigment, Asthaxanthin. Yields of asthaxanthin depend on dissolved oxygen absorption at low aeration rate.

10. Colors from algae

Rhodophyta produces Phycocyanins and Phycoerythrins piecemeal from chlorophylla. Cyanophyta and Cryptophyta produce red or blue colors, Phycobiliproteins.

Flavor Enhancers For Food

You can outline flavor enhancers as substances which increase the sweetness of the flavor of another substance. Flavor potentiators are substances that can increase the perceived intensity of the flavor of another substance.

Top 10 flavor enhancers

A wide variety of flavor enhancers are available in the market. The top 10 flavor enhancers are:

  1. Glycine
  2. Disodium ribonucleotides
  3. Guanosine monophosphate
  4. Inosinic acid
  5. Calcium inosinate
  6. Glutamic acid
  7. Disodium guanylate
  8. Ethyl maltol
  9. Glutamate flavoring
  10. Disodium inosinate

Major products available in market containing these food enhancers may include:

  • Salsa
  • Banana Peppers
  • Unsweetened ketchup
  • Thai red curry paste
  • Dijon Mustard
  • Bragg’s Liquid Aminos
  • Bragg’s Nutritional Yeast
  • Trader Joe’s Everything Bagel Seasoning
  • Liquid Smoke
  • Trader Joe’s 21 Salute Seasoning

What are Nutrient Supplements?

Nutrient supplements are substances which you can use in food making. These supplements compensate the nutrients that may lose during food making.

For example,

  • Fermentation of butter with vitamins A and D
  • Enrichment of wheat flour with lysine, calcium, thiamin, niacin and iodization of everyday salt.
  • Multiple types of research and health laboratories employ these products, and health- food stores sell them as nutritional supplements.
  • Microorganisms produce amino acids, nucleotides, vitamins, and organic acids are in tons, such as, the lysine specified by some croakers to treat herpes Simplex infections. It is a product of the bacterium Corynebacterium glutamicum.
  • Vitamin B (cyanocobalamine) 12 and vitamin B (riboflavin) are 2  produced by a bacterium and a mold.
