The blue item in the photo is a food‑grade oxygen absorber (desiccant) packet, often labeled “BST” (for “best” or brand identification). These small packets are commonly placed in packaged foods—like the pretzels shown—to absorb moisture and oxygen from the environment, helping preserve freshness and prevent spoilage.
How It Works1. Moisture control: The packet contains materials such as silica gel or iron powder that attract and trap water molecules, keeping the product dry.
2. Oxygen absorption: Some packets chemically bind with oxygen, slowing oxidation and extending shelf life.
3. Safety: Food‑grade packets are non‑toxic and designed to be safe even if accidentally ingested in small amounts, though they are not meant to be eaten.
What the Markings Mean- 25mm: likely refers to the diameter of the packet.
– BST: may indicate the brand or type of absorber.
– Cart No 230038: a batch or catalog number for inventory purposes.
Consumer Tips- Do not ingest: While generally safe, the packet should be discarded after opening the food package.
– Check packaging: Manufacturers often include a note about the presence of desiccant packets.
– Storage: Keep food packages sealed until ready to use to ensure the desiccant works effectively.
In summary, the blue object is a harmless food‑grade desiccant used to preserve snacks like the pretzels shown, ensuring they stay fresh by absorbing moisture and oxygen. 🚫🍬👍
