DuPont has unveiled an expanded lineup of the Holdbac Protective cultures range to target contamination in the mild acidic environments of cheese and fresh yogurt manufacture while maintaining flavour.

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

Tailormade to the cheese manufacturing environment, Holdbac YM-XPK can help to maintain optimum cheese quality throughout shelf life by effectively controlling fungal spoilage and waste and enhancing flavour attributes. In addition to optimising flavour and manufacturers cost base, the product shelf life extension may bring opportunities to increase volume by expanding trading areas.

In addition, Holdbac YM-XPM has been created to prolong freshness in mild yogurt and fresh fermented dairy products. The range maintains the mild taste attributes that consumers prefer, while simultaneously controlling spoilage.
