Winter signals a drop in temperature, leading people to wear more clothes, leaves falling with the wind, and grass withering. Additionally, some common alcoholic beverages and drinks undergo subtle changes, such as fruit wines, fruit vinegars, and fruit and vegetable juices developing turbidity and sedimentation issues within a short shelf life, which affects product market sales.
Products like fruit wines, fruit vinegars, fruit and vegetable juices (clear juices), rice wines, and clear rice wines are expected to present consumers with a highly clear and transparent appearance, free of sediment or with minimal sediment. Excessive sedimentation may lead consumers to believe the product has spoiled and is undrinkable. The causes of turbidity and sedimentation in fruit wines and vinegars are generally twofold: first, inadequate sterilization leading to microbial spoilage; second, insufficient filtration precision, resulting in the presence of large molecular impurities such as soluble and semi-soluble plant fibers, colloids, and foreign proteins. These impurities aggregate and precipitate during shelf life due to temperature drops and charge adsorption effects.
This is why some alcoholic beverages appear clear and transparent in summer but develop significant sedimentation in winter. The precipitated substances, such as colloids and foreign proteins, are soluble macromolecular impurities that do not necessarily compromise product quality but negatively affect sensory appeal. So, how can production enterprises avoid this situation?
Most products experiencing the above issues are processed using methods like natural sedimentation, filter cartridges, plate and frame filters, or diatomaceous earth, which lack sufficient filtration precision. Only by adopting advanced membrane separation ultrafiltration technology (0.1μm filtration precision) can these soluble macromolecular impurities be effectively removed while ensuring the permeation of beneficial components, thereby enhancing product quality and preventing turbidity and sedimentation over time.
