Laboratory analysis and quality control at SUPERSENTIALS

Transparency, rigor and security in every batch

At SUPERSENTIALS, we believe trust is built by demonstrating how we work. We grow and freeze-dry our own microgreens, and every batch undergoes a rigorous quality control process designed to ensure safety, purity, and true quality . This page summarizes how we analyze our products, why we do it, and what it means to you when you choose our natural, freeze-dried microgreen supplements.

Analyses performed on each batch

Each batch is tested in an accredited independent laboratory. These tests focus on ensuring the food safety of our products.

Heavy metals

We test each batch for arsenic, lead, mercury, and cadmium to ensure they are free of contamination.
Our results remain below the limit of quantification, meaning there are not enough to measure them, a sign of the purity of our crops and our production system.

Microbiological safety

Each batch is analyzed to confirm the absence of pathogenic microorganisms such as Listeria monocytogenes , Salmonella , E. coli or staphylococci .
Our freeze-drying process produces extremely low water activity, which prevents microbial growth and ensures product stability.

These analyses are systematically repeated in each batch , which guarantees the safety of each of our products.

Periodic nutrient analysis

In addition to mandatory batch analyses, we perform regular nutritional analyses to evaluate key vitamins and phytonutrients, such as glucoraphanin, a precursor to sulforaphane.
These analyses do not need to be repeated for each batch because our cultivation and freeze-drying process is consistent and controlled. Their objective is:

  • verify the stability of nutrients over time

  • to guarantee that the levels we declare are real

Why this system is reliable

Our quality policy is based on criteria recognized in the food industry.
Heavy metals and microbiology are the parameters that determine the safety of any food or powdered supplement.
Controlling these two aspects in each batch is the most honest and effective way to ensure that our freeze-dried microgreens reach you in optimal condition.

The most comprehensive periodic analyses ensure that the nutritional profiles —natural vitamins, glucosinolates and other phytonutrients— are consistent and reflect the true value of our young plants.

Our control process

Our process is designed to maintain the highest quality from seed to final product.

  1. Grown in our own facilities under controlled conditions and suitable for products intended for human consumption

  2. Harvest at the moment of maximum nutritional concentration

  3. Washing and drying

  4. Freeze-drying in a cold environment, without heat, a few hours after harvest

  5. Cold milling and hermetically sealed

  6. Batch analysis in an external laboratory

Each stage contributes to preserving the natural nutritional value of our microgreens and ensuring a clean, safe, and stable supplement.
