Natural solutions for beverage preservation

All foodstuffs need preservation, the inevitable delay between market and table force us to rely upon refrigeration, preservatives and logistics to avoid inevitable decay and deterioration, OrganoFresh is now available to help keep your beverages fresher for longer.


Organo Fresh represents the evolution of our range of natural preservatives. Our science team initially formatted the Brew Shield and Wine Shield range of products to meet a very real but specific need in these two beverage categories.

Through the success of these applications, our focus has expanded to the demand for natural, organic, and high-impact preservation in a broader range of products. Reactions involving oxygen and radical oxygen species are not limited to beer and wine.

Oxidation is a common and major challenge throughout the food and beverage industry, its impact on flavor, color, and aroma costs the industry billions of dollars every year in rejected, out of code and ruined product.

Manufacturers are increasingly looking for more healthy ways to preserve and protect their products, our registered organic Organo Fresh product provides an ideal solution. The active ingredients in Organo Fresh have proven efficacy in the defense and protection of food products against oxidation, staling and extending freshness and shelf life.


Natural beverage brands trust Organo Fresh to protect their products by maintaining freshness for longer.

Our clients, who use exclusively natural ingredients in their products, can now market them as 100 % natural while enjoying the benefits of an effective antioxidant preservative. With Organo Fresh, their products simply last longer, giving rise to improved customer satisfaction even with older stock.


Coffee is a highly volatile beverage with major challenges in maintaining freshness. Most coffee companies grind beans prior to serving for exactly this reason. This leaves mass retailers of ground coffee in a bind. In spite of foil packaging, nitrogen flushing, vacuum packing and other interventions, ground coffee has an extraordinarily short “fresh window”.

Oxidation and chemical degradation of coffee oils and acids cause decline in desired flavors and the introduction of undesirable flavors all of which present real quality issues for the manufacturer, most especially with more refined coffee products such as cold brew coffee.

Organo Fresh has been highly effective in preserving freshness in ground and cold brew coffee, allowing producers to better cope with long shelf life and storage timeframes.


Tea suffers from similar stability issues as coffee. Ultimately, both ingredients are mass produced but have long logistics, warehousing, and lead times from packaging to sale.

Organo Fresh has delivered amazing results in preserving brewed tea beverages that previously struggled with flavor and product stability. Our clients have been able to move away from undesirable synthetic preservatives to our extract, resulting in excellent customer feedback and improved market value.


Organo Fresh has been applied in a wide variety of beverages requiring preservation. These include juice, low calorie carbonated drinks, kombucha and more.

Our clients are looking to deliver healthier more natural ingredients to their customers at the same time customers are demanding more natural, organic and healthier products, they are seeking out products with natural preservatives and products that are preserved using Organofresh have a clear advantage over their competitors, creating greater market value and share.
