How Does the Electric Salt Spoon Work? The Science Behind Taste Enhancement
“The device sends electricity from the spoon to your tongue to give you the sensation of saltiness. It’s a weak electric current that concentrates sodium ion molecules in your food, adding a stronger umami and salt flavor to low-sodium foods.”
– CNET Technology Review TeamIon Concentration Technology
According to research from Meiji University’s Dr. Homei Miyashita Laboratory, the Electric Salt Spoon uses a unique current waveform that controls the movement of ions. When the person puts the spoon in their mouth, they complete an electrical circuit, allowing a weak electrical current (0.1-0.5 mA) to flow through the food.
Award-Winning Research Foundation
The technology behind Kirin’s spoon won the 2023 Ig Nobel Prize for unusual scientific research. The researchers first published their thesis in 2011 and have since developed spoons, forks, and chopsticks that pass electric currents into food to enhance taste perception.

Health Benefits & Medical Research
Addressing Japan’s Sodium Crisis
According to Ministry of Health, Labour and Welfare data, Japanese adults consume 10.1g of salt daily – more than double the WHO’s recommended 5.0g intake. Research shows that approximately 60% of people trying to reduce salt intake are dissatisfied with low-sodium food taste.

Clinical Testing Results
In controlled studies with 31 participants aged 40-65 currently reducing salt intake:
- 94% Success Rate: 29 out of 31 participants reported increased saltiness perception
- 30% Salt Reduction: Maintained taste satisfaction with significantly less sodium
- Umami Enhancement: Additional improvement in savory taste beyond saltiness
Important Safety Information
People with pacemakers or other medical electrical devices should not use the Electric Salt Spoon. The device is not recommended for minors. Always consult healthcare providers before significant dietary changes.
Real User Experience & Testimonials
“It tasted decent, but I do tend to like my food on the salty side. Then, I gripped the Electric Salt Spoon, making sure my hand made contact with the sensors. The difference was noticeable – the broth suddenly had more depth and saltiness.”
– Tom’s Guide Hands-On ReviewerLearning Curve & Usability
According to multiple expert reviews, the Electric Salt Spoon has a moderate learning curve:
- Requires contact with both handle sensors and food contact with spoon tip
- LED indicator system helps users know when device is active
- Most users adapt to the grip technique within 2-3 uses
- Effect is most noticeable with liquid-based foods

Frequently Asked Questions
How does the Kirin Electric Salt Spoon work?
The spoon uses a weak electric current (0.1-0.5 mA) to concentrate sodium ions in food, enhancing the perception of saltiness without adding actual sodium. When you put the spoon in your mouth, you complete an electrical circuit that stimulates taste receptors.
Is the electric current safe?
Yes, the device uses a very weak electric current that is safe for most users. However, people with pacemakers or other medical electrical devices should not use it. The current is similar to what you might experience with a 9V battery on your tongue.
What foods work best with the Electric Salt Spoon?
According to Kirin, the spoon works best with liquid and semi-liquid foods including soups, broths, curry, fried rice, ramen noodles, and other meals with sauce. The effect is most noticeable with foods that have existing sodium content.
How long does the battery last?
The CR2 lithium battery provides extended use, though Kirin hasn’t specified exact battery life. The device includes LED indicators to show battery status and activity level.
Can I use it for weight loss or medical diets?
While the spoon can help reduce sodium intake, it’s not specifically designed for weight loss. People on medical diets should consult their healthcare provider before use. The device is most beneficial for those trying to reduce salt intake for health reasons.
When will it be available in the United States?
Kirin Holdings expects to launch the Electric Salt Spoon in North America sometime in 2025, likely in Q2. The company is currently working on regulatory approvals and distribution partnerships.
How much does it cost and is it worth the price?
The Electric Salt Spoon costs approximately $125-127 USD. While expensive for a spoon, it’s positioned as a health technology device. For people who need to significantly reduce sodium intake, the one-time cost may be justified versus ongoing medication or health complications.
