Formerly a manufacturer’s dream, today DuPont market-driven science took on the challenge and made it a reality.

HOLDBAC® YM-XP Protective cultures are designed to provide optimum protection against yeast and mold, specifically in the mild acidic pH conditions typical in cheese and mild yogurt. This can result in dramatic improvements in eliminating spoil age and waste, not only during manufacturing, but also in the retail and consumer environments.

Control fungal spoilage in cheese with HOLDBAC® YM-XPK

The multiple steps involved in cheese manufacture and handling processes – such as separation, salting/brining, ripening at non-refrigerated temperatures, slicing/shredding and portion packaging all bring increased risk of cross-contamination.

Without effective inhibition, the high salt content and mild acidic pH of the cheese matrix is not enough to control the growth of yeast and mold. Broader spectrum protective cultures are simply not as effective in this mild acidic environment, risking more rapid fungal growth. Building on the innovation know-how seen in the HOLDBAC® Protective cultures range, DuPont scientists have created an expert inhibition solution that is tailor-made to the cheese manufacturing environment.

HOLDBAC® YM-XPK can help to maintain optimum cheese quality throughout shelf-life by effectively controlling fun gal spoilage and waste, and enhancing flavor attributes. In addition to optimizing flavor and manufacturers' cost base, the product shelf-life extension may bring opportunities to increase volume by expanding trading areas.

Prolong freshness in mild yogurt and fresh fermented dairy products with HOLDBAC® YM-XPM

Mild and very mild acidic tasting yogurt and fresh fermented dairy products are increasingly popular with consumers. However, this has brought a significant technological challenge for manufacturers as the mild and very mild pH of these products makes them even more sensitive to fungal spoilage. DuPont has developed the HOLDBAC® YM-XPM range of dedicated expert solutions which maintain the mild taste attributes that consumers prefer, while simultaneously controlling spoilage.

Due to secured product quality throughout shelf-life, brands can be protected throughout the uncertain environments of logistics and distribution, with the bonus of Clean Label credentials as preferred by consumers.

HOLDBAC® YM-XP Protective cultures expertise

DuPont has over 15 years of innovation and expertise in protective cultures for yeast and mold control in fermented dairy applications. The HOLDBAC® YM-XP Protective cultures range is a powerful new weapon in manufacturers' armoury against fungal spoilage, to help ensure production of longer-lasting, fresher-tasting fermented dairy products.

HOLDBAC® YM-XP Protective cultures will protect and maintain flavor in a wide range of fresh fermented dairy products, including drinking yogurt, Quark, Tvarog, white brine and semi-hard cheeses and sour cream. The cultures can simply be added to the milk together with the starter culture, ensuring a simple and efficient manufacturing process.
