The core challenge faced by traditional salt reduction is that salt (sodium chloride) is not only a source of salty taste, but also serves multiple functions such as enhancing flavor, suppressing bitterness, and improving texture. Simply reducing salt content can lead to:

Lack of saltiness: the most direct issue.

Diminished flavor: Food becomes' tasteless'.

Highlight bitterness and odor: The negative taste of raw materials (such as certain potassium salts and peptides) that were originally masked by saltiness will be revealed.

Taste deterioration: The texture may become loose or viscous.

Therefore, developing salt reducing products is not only about reducing sodium chloride, but also requires the use of salt substitutes (such as potassium chloride), flavor enhancers, or process adjustments to compensate for the aforementioned deficiencies. Objective, accurate, and efficient taste evaluation is the key to success in this process. However, traditional artificial sensory evaluation has limitations such as strong subjectivity, fatigue, and difficulty in standardization. JapanINSENTThe electronic tongue precisely compensates for these shortcomings.

JapanInsentThe electronic tongue, with its technical features, is very suitable for complex taste analysis:

Biomimetic lipid membrane sensor technology:The sensor surface is covered with a special lipid membrane, which simulates the response mechanism of taste buds cells in the human tongue to taste substances. When taste substances are adsorbed on the membrane, it will cause a change in membrane potential and be detected.

High sensitivity and objectivity:Capable of detecting subtle differences below the human taste threshold and providing absolute output, the results are not affected by subjective emotions, physical condition, or environment.

No taste fatigue:It can continuously and repeatedly test a large number of samples to ensure data consistency and reliability.

Taste decomposition ability:Complex taste information can be broken down into several basic taste intensities for quantification: salty, sour, bitter, sweet, umami, astringent, as well as bitter aftertaste, astringent aftertaste, and fresh aftertaste.

Specific applications in the development of salt reduction products

Japanese electronic tongue is widely used in the entire process of salt reduction products, mainly focusing on the following aspects:

1. Screening and optimization of salt substitutes

Electronic tongue can accurately quantify different formulas (such asNaCl:KClThe intensity of saltiness and bitterness in proportion.

2. Evaluate the overall taste balance of salt reducing products

The electronic tongue can draw a complete taste profile radar map of reduced salt products and full salt products.

3. Quality control and batch stability assessment

It is crucial to ensure taste consistency in each batch of mass-produced salt reducing products.

4. Competitive Analysis

Objectively compare the advantages and disadvantages of our own salt reducing products with competitors in various taste indicators.

Practical application cases

Reduced salt soy sauce:

Challenge: After reducing salt, both salty and umami flavors (derived from amino acids) decrease, resulting in a bland product.

Application: Use electronic tongue to compare salt reducing soy sauce with different processes or added with different flavor enhancers, find the solution that can maximize the recovery of the "salty fresh synergistic effect", and monitor whether any adverse bitterness is introduced.

Reduced salt soup seasoning and instant noodle seasoning package:

Challenge: The ingredients are complex, and reducing salt affects the overall flavor balance.

Application: Through taste profile analysis, accurately adjust the ratio of salt, substitutes, sugar, and umami to ensure that the final product reduces salt30%In this case, it can still maintain a satisfactory rich taste.

Reduced salt meat products (such as ham, sausages):

Challenge: Salt also plays a role in extracting protein, improving water retention and texture in meat products. Reducing salt may lead to a deterioration in taste.

Application: Although electronic tongue does not directly detect texture, it can monitor taste release characteristics that may be indirectly affected by texture changes (such as flavor persistence and intensity), and combine them with sensory evaluation to optimize formulations.

The relationship between electronic tongue and artificial sensory evaluation

It should be emphasized that electronic tongue is not meant to replace artificial sensory evaluation, but rather a powerful complementary tool.

Electronic tongue: Provides objective, quantitative, and highly repetitive basic taste data, adept at analyzing "what" and "how much".

Artificial senses: provide subjective and comprehensive evaluations of overall preference, flavor complexity, taste and texture, and are skilled at answering questions such as "which one you like" and "how you feel".
