Q: We are looking to clean agar residue from a belt in a machine that pours agar. What do you recommend?

A: For cleaning agar from a belt via manual cleaning, depending on you preference for a powder or liquid detergent, respectively, we would recommend 1-2% concentrations, warm temperatures, of Alconox® Powdered Precision Cleaner or Liquinox® Critical Cleaning Liquid Detergent, followed by thorough rinsing.

If the belt is intended to be removed from the machine and cleaned in a washer or high pressure spray system, the low foaming emulsifiers in Alcojet® Low Foaming Powdered Detergent and Solujet® Low-Foaming Phosphate-Free Liquid for powdered and liquid detergent formats, respectively, are a great answer.  If a phosphate free powder is sought: Tergajet® Low-Foaming Phosphate-Free Detergent

These options can also be used to remove agar residue from glassware, instruments and other labware surfaces. 

What is Agar?

Agar is a gelatinous substance that comes from red algae and seaweed. It’s particularly valued for its ability to gel without the need for refrigeration, which sets it apart from many animal-based gelatin products. Here are a few key points about agar:

  1. Culinary Uses: Agar is widely used in cooking as a vegetarian substitute for gelatin to thicken and stabilize desserts like jellies, puddings, and custards. It’s popular in Asian cuisine and is known for creating a firmer texture than gelatin.
  2. Scientific Applications: In microbiology, agar is a critical component of culture media used for growing bacteria, fungi, and other microorganisms. Agar plates provide a solid surface infused with nutrients necessary for microbial growth.
  3. Other Uses: Beyond food and science, agar is also used in various industrial applications, including as a clarifying agent in brewing, for sizing paper and fabrics, and in cosmetics as a thickener and moisturizer.

Agar’s ability to gel at room temperature and remain stable at high temperatures makes it highly versatile in many fields.
