However, in the apple juice production process, factors such as raw materials, oxidation reactions, extraction processes and storage conditions often lead to problems such as juice darkening, color instability and lack of transparency, which affect the appearance of the product and its marketability.<\/p>\n\n\n\n<p>To improve the color and transparency of apple juice, many food processing enterprises use activated carbon for decolorization. Activated carbon has a well-developed porous structure and strong adsorption ability, effectively removing pigments, oxidation products and some impurities from the juice, thus improving the appearance and stability of the finished product.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why does apple juice need discoloration?<\/h2>\n\n\n\n<p>The color of apple juice is affected by various factors such as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Different varieties of apples<\/li>\n\n\n\n<li>Oxidation during juicing and heating<\/li>\n\n\n\n<li>Enzymatic darkening<\/li>\n\n\n\n<li>Excessive storage time<\/li>\n\n\n\n<li>Differences in raw material maturity<\/li>\n<\/ul>\n\n\n\n<p>In industrial production, if the apple juice is too dark or the color is uneven between batches, it directly affects the market appeal of the product. Therefore, decolorization is a crucial step in the apple juice refining process.<\/p>\n\n\n\n<p>Using activated charcoal for discoloration primarily achieves the following goals:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Decrease in juice color<\/li>\n\n\n\n<li>Removal of certain substances that cause tarnishing<\/li>\n\n\n\n<li>Improved transparency<\/li>\n\n\n\n<li>Improved uniformity of product appearance<\/li>\n\n\n\n<li>Increasing competitiveness in the market<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Principle of action of activated carbon in decolourization of apple juice<\/h2>\n\n\n\n<p>Activated carbon is a porous adsorbent with a large specific surface area and an abundance of microporous and mesoporous structures. In the process of fruit juice decolorization it acts mainly by physical adsorption, adsorbing on its surface coloring substances, oxidation products and some organic impurities from the juice.<\/p>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table class=\"has-background has-fixed-layout\" style=\"background-color:#abb7c21a\"><thead><tr><th>Parameter<\/th><th>Significance<\/th><\/tr><\/thead><tbody><tr><td>Type<\/td><td>Food grade powdered activated carbon (PAC)<\/td><\/tr><tr><td>Specific surface area<\/td><td>800-1200 m\u00b2\/g<\/td><\/tr><tr><td>Iodine number<\/td><td>900-1100 mg\/g<\/td><\/tr><tr><td>Adsorption of methylene blue<\/td><td>120-200 mg\/g<\/td><\/tr><tr><td>Particle size<\/td><td>100-325 mesh<\/td><\/tr><tr><td>Humidity<\/td><td>\u226410%<\/td><\/tr><tr><td>Ash content<\/td><td>\u22645-8%<\/td><\/tr><tr><td>pH<\/td><td>6-9<\/td><\/tr><tr><td>Iron content<\/td><td>Conforms to food standards<\/td><\/tr><tr><td>Soluble substances<\/td><td>Conforms to food standards<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion<\/h2>\n\n\n\n<p>PureRus Carbon offers highly effective solutions for apple juice decolorization, helping producers achieve a clearer appearance, consistent quality and consistent production results.
