چکیده :

Ensuring optical clarity and sensory integrity of non-alcoholic malt beverages during storage is essential for consumer acceptance and commercial success, particularly in markets where alcohol-free products are mandated or preferred. This review synthesizes recent advances in understanding the chemical and physical mechanisms that drive haze formation, flavor deterioration, and microbiological spoilage in non-alcoholic malt beverages, and presents evidence-based strategies to maintain product quality. We evaluate raw-material approaches, including selection of low-haze barley cultivars and lipoxygenase-deficient (LOX-less) malts; process interventions such as optimized mashing, kettle fining, and controlled whirlpool regimes; and stabilization techniques including polyvinylpolypyrrolidone (PVPP), silica gel, chitosan, and combined adsorbent systems. Packaging and storage factors—oxygen ingress, headspace management, light exposure, temperature, and humidity—are examined for their contributions to oxidative aging and light-induced off-flavors. Analytical approaches for haze prediction and shelf-life assessment are discussed, and practical protocols suitable for both small-scale producers and industrial manufacturers of non-alcoholic malt beverages are proposed. Emerging solutions such as breeding for haze resistance, composite stabilizers, and active packaging with oxygen scavengers are also reviewed. The study concludes that an integrated, multilevel strategy combining raw material control, targeted stabilization, and optimized storage conditions maximizes clarity retention and extends the sensory shelf life of non-alcoholic malt beverages.
