A Review on New Trends, Challenges and Prospects of Ecofriendly Friendly Green Food-Grade Biolubricants

The standard operating procedure adopted to health and safety standards for food, beverage, and drug manufacturers are the most priority requirements to keep the business of feeding and healing society on the right track. Biolubricants used in particular should never be allowed to contaminate the raw materials, intermediates, and finished products. The consequences of biolubricant-contaminated products are rarely more acute than in the food processing industry. Therefore the food processing industry presents unique challenges to lubricant formulation engineers, lubricant marketers, plant lubrication engineers, and equipment designers. The food processing and pharmaceutical industries face additional challenges in selecting optimal food-grade biolubricants. Food-grade biolubricants used in these industries have specific requirements, protocols, and performance expectations that exceed typical industrial lubrications. Biolubricants formulated from biobased resources are a new trend in "green" food-grade biolubricants due to their low-cost renewable natural raw materials, biodegradability, environmental friendliness, low toxicity besides their excellent lubrication properties. In this review, the discussion will focus on the future trends, challenges, and prospects of green food-grade biolubricants applicable to the food, beverage, and drug manufacturing industries.
