What is Yuka made out of? A look at the app's components and data

3 min read

With millions of active users worldwide, the Yuka app has transformed how consumers evaluate products by decoding complex labels. This widespread adoption naturally leads to the question: what is Yuka made out of? The answer lies not in physical ingredients, but in its sophisticated combination of technology, data, and methodology that empowers shoppers to make healthier choices.

Quick Summary

The Yuka app is a mobile barcode scanner built with a product database and a proprietary algorithm, which rates items based on nutritional quality, additives, and organic status for foods, or ingredient risk for cosmetics.

Key Points

The Yuka app and yuca are not the same: The query refers to the mobile application, not the tropical root vegetable known as cassava.
Barcode scanning is the core technology: The app uses a fast barcode scanner to pull up product information from its large database in real-time.
Product data comes from users and brands: Yuka's extensive database is built from user contributions and data provided directly by manufacturers.
An algorithm rates products objectively: Scores are generated by a proprietary algorithm that is independent of brand influence and based on scientific criteria.
Food is rated by nutritional quality, additives, and organic status: Food scores are 60% nutritional quality (based on Nutri-Score), 30% presence of additives, and 10% organic certification.
Cosmetics are rated by ingredient risk: Cosmetic scores are based entirely on the potential health and environmental risks of their ingredients, with a single hazardous ingredient significantly lowering the score.

Decoding the Yuka App's Composition

Many people encounter the word "Yuka" and wonder about its composition, but it is important to distinguish between the Yuka app and the starchy root vegetable, yuca. While the root vegetable consists of fiber, vitamin C, and carbohydrates, the mobile application's composition is entirely digital. The Yuka app is engineered from several key components that work together to provide instant, informative product analysis to health-conscious consumers.

The Core Technology: Scanning and Database

At the heart of the Yuka app's functionality is a high-speed barcode scanning module integrated into the mobile application. When a user scans a product's barcode, the app queries its extensive database to retrieve the product's information. This database is not static; it is constantly evolving and expanding through a two-pronged approach:

User Contributions: When a product is not yet in the system, users can contribute information by taking pictures of the product and its label. This crowdsourced data is then subject to verification.
Brand Data: Yuka also partners with brands that provide direct access to their product data, ensuring accuracy and consistency with what appears on the product label.

The app's backend is a complex architecture designed to handle millions of scans, manage this vast database, and perform real-time data analysis to generate a product's rating.

The Scoring Algorithm: How Ratings Are Made

Once the product data is retrieved, a proprietary algorithm, developed by Yuka's team of experts, takes over to generate the score. The rating criteria are weighted differently for food and cosmetic products.

Food Product Scoring Criteria

For food items, the rating is broken down as follows:

Nutritional Quality (60%): This is based on the European Nutri-Score calculation method, which considers positive elements like fiber, protein, fruits, and vegetables, and penalizes negative elements such as sugar, saturated fat, and salt.
Presence of Additives (30%): Yuka assesses the risk level of a product's additives based on scientific research and reports from reputable health organizations. If a high-risk additive is present, the product's score is automatically capped at a low level.
Organic Dimension (10%): Products with an official organic certification receive a positive adjustment to their score.

Cosmetic Product Scoring Criteria

Cosmetic products are evaluated solely on the risk level of their ingredients, based on the latest scientific data. Each ingredient is assigned one of four risk levels:

Risk-free
Low risk
Moderate risk
Hazardous

The final product score is heavily influenced by the highest-risk ingredient present. For example, a single hazardous ingredient will automatically give the product a score below 25/100.

A Commitment to Independence

A critical component of Yuka's composition is its commitment to independence and transparency. The company does not accept money from brands or manufacturers to influence scores or recommendations, and the app does not contain paid advertising. This objectivity is key to building consumer trust and driving adoption. Yuka funds its operations through premium subscriptions and the sale of physical products like books, ensuring its evaluations remain unbiased.

Comparison of Yuka's Scoring Methodologies


Feature	Food Product Evaluation	Cosmetic Product Evaluation
Scoring Basis	Primarily Nutri-Score, additives, and organic status.	Based exclusively on ingredient risk level.
Key Factors	Considers sugar, saturated fats, salt, calories, protein, fiber, and fruit/veg content.	Analyzes potential health and environmental risks like endocrine disruption, allergens, and carcinogens.
Risk Assessment	Additives are assigned risk levels, impacting the score significantly if high-risk items are present.	The highest-risk ingredient determines the overall maximum score.
Organic Weight	Certified organic status contributes 10% to the overall score.	Organic certification is not a primary factor in the scoring algorithm for cosmetics.

Conclusion

In summary, the Yuka app is made out of a sophisticated blend of technology, data, and an independent, science-based algorithm. Far from a simple list of ingredients, its composition includes a robust barcode scanner, a dynamic, user-fed database, and a scoring system that prioritizes nutritional quality and ingredient safety. This digital architecture empowers millions of consumers by providing transparent, easy-to-understand product evaluations directly at their fingertips. By understanding what Yuka is truly made of, users can more effectively use this tool to make informed choices about the products they buy.

For food products, Yuka's nutritional score accounts for 60% of the total rating and is based on the European Nutri-Score method, evaluating factors like calories, sugar, and fiber.

If a cosmetic product contains an ingredient that Yuka classifies as 'hazardous,' its score will automatically be rated below 25/100, landing it in the 'Bad' category.

No, the scoring systems for food and cosmetics are different. Food ratings consider nutritional value, additives, and organic status, while cosmetic ratings focus solely on the risk level of ingredients.

Yuka employs a system of controls, including algorithms and a dedicated team, to verify user-submitted data for accuracy before it becomes a permanent part of the database.
