Mosh and Moah Definition
Moh (Mineral Oil Hydrocarbons) are mineral based hydrocarbons obtained from crude oil, coal, gas or biomass that can potentially contaminate food production undermining food safety. Moh can be divided into two main categories:
The real challenge of this last years has been to establish a detection methodology to fix the ADI (Acceptable Daily Intake) value, which is the acceptable daily ingestion tolerance for humans. Generally speaking experts think that Moah percentage (ref. 3-7 PAC) settles at 15-35% of total Moh. Although a step forward has been made in detection methodology it is still hard to imagine long-term implications, especially regarding liver deposits.
Food Safety: Moh Contamination Sources
Apart from detection methodology it is still very difficult to establish the effective source of a Mosh Moah food contamination. Main potential occasions might occur from:
Take into account that hydrocarbons and light mineral oils are extremely volatile. Even if there's no direct contact, hydrocarbons can evaporate and later on re-condense on food.
Foodgrade lubricants: Pakelo Non Tox M Series
Pakelo Non Tox M series was born with the specific aim to help food and beverage industries to enhance food safety in view of a future stricter regulation on Mosh and Moah limits. This series is made of three key products which are both NSF compliant and Mosh Moah Free:
Pakelo products of Pakelo Non Tox M range are also: allergen-free, OGM-free and Halal-compliant.
Tribological test on Pakelo Foodgrade Lubricants
Pakelo tested its whole range of non-toxic lubricants to understand if the formulation changes to create Mosh and Moah free lubricants could affect their performance. In the graphic below we confronted friction coefficients of a standard mineral-based foodgrade lubricant (green line), a standard synthetic-based foodgrade lubricant (yellow line) and a product of the new Mosh and Moah free series Non Tox Oil M ISO 46 (blue line). Under the same viscosity, friction coefficient test reveals a -20% for Non Tox Oil M ISO 46 compared with other products. It means that this product is as good for food safety as it is for the good functioning and performance of mechanical organs.
You might rightly wonder if there is any Mosh and Moah limit fixed by law to respect. Like we mentioned in the premises at the beginning of 2021 EFSA has not established official parameters yet. In its "Scientific Opinion on Mineral Oil Hydrocarbons in Food" (Contam Panel) in 2012 EFSA affirmed that in absence of further studies ADI (Acceptable Daily Intake) thresholds will be those established by JECFA in 2002 (Joint Fao - Who Commitee on Food Additives). On low viscosity mineral group II and III oils the Commitee established a limit of: 10 milligrams per day per kilogram body weight referred to Mosh only. However, this limit has been suspended by Who itself in 2012 waiting for more accurate evaluations on the topic.
The German Case History
German Federal Ministry of Food and Agriculture (BMEL in German) has already taken a position autonomously. German limits on Mosh and Moah presence on packagings are:
We don't know when, but it is pretty obvious that both EFSA and the World Health Organization (Who) will also take a decision on this delicate matter in the next future.
