Talc mineral for Food
Talc is useful and harmless in food products. Talc mineral in food is chemically inert and passes through the body without being digested. It is thus approved as a carrier for food colourings and as a separating agent in such products as rice, powdered dried foods, seasonings, cheese, sausage skins or table salt. The hydrophobic talc particles attach themselves to those of the food, protecting them and preventing clumping.
One key application is in chewing gum. Here, the low alkaline level of our talc is important. Thanks to its chemical inertness, it does not react with the acidic components of fruit chewing gum.
Talc for Olive Oil Production
Native olive oil is generally produced in a mechanical process at temperatures that do not harm the quality of the oil. After the harvest, the olives are washed, pressed and then ground into a paste. Water is then added, and the solid matter is separated from the oil and water in a centrifuge. After a while, the oil that separates from the water is skimmed off and bottled.
Often, it is not easy to separate the oil from the solids. This is the case when “difficult" olives are used. These are most likely to end up in the process at the beginning and end of the season, when the olives contain either too little or too much water. Bad weather during ripening increases the proportion of difficult olives. When the paste is produced, difficult olives release fine solids that act as a natural emulsifier. They attract numerous droplets in the water phase so that these cannot be skimmed off.
Talc solves this problem. When just a small amount is added to the olive paste, the talc adsorbs the emulsifier particles. It also joins the oil droplets to form larger drops that are easier to centrifuge. Talc itself is chemically inert, with the result that it does not alter the characteristics of the paste or the oil. Microtalc FC 8-AW from Mondo Minerals is ideal for this application. This grade is highly pure, and its active surface is exceptionally large thanks to the extremely fine particles. Thus, this talc is especially lipophilic. Our studies show that producers using our product can save 70% of the talc quantity compared to the conventional talcs from other manufacturers.
Our Amsterdam plant is certified according to ISO 22000:2005 to assure conformity for food applications. Inspecta Certification has granted this certificate as proof that the food safety management system of Mondo Minerals BV, The Netherlands, complies with the requirements of standard ISO 22000:2005. Certification covers sales, production and deliveries of talc products to cosmetic, food and pharma applications, Amsterdam. The certificate is valid on condition that the food safety management system of the organization remains in compliance with the aforementioned standard and the General Regulations ABC 200.
In addition, we run HACCP and GMP systems to fulfil requirements of food and cosmetics applications. For most of these applications, in most EU countries a GMP quality system with HACCP is required. Mondo Minerals is one of the few suppliers who manufacture talc grades according to this standard.
HACCP (Hazard Analysis and Critical Control Points) is a systematic preventative approach to food safety that addresses physical, chemical and biological hazards as means of prevention rather than finished product inspection. "cGMPs" or "current Good Manufacturing Practices" is a term that is recognized worldwide for the control and management of manufacturing and quality control testing of pharmaceutical products. The term is also used for food and feed production, where it is mandatory.
