Deep freezing refers to the rapid cooling of products. This offers many benefits, as it extends the product\u2019s shelf life, maintains its safety, preserves its physicochemical stability, and keeps it fresh.<\/p>\r\n<p>For this reason, storing products at very low temperatures has become an integral part of the bakery and pastry industry. As the shelf life of products is protected against all types of spoilage, freezing is often the preferred method in many cases.<\/p>\r\n<ul>\r\n\t<li>How deep freezing works<\/li>\r\n<\/ul>\r\n<p>A complete freezing system cools the food product with cold air until it reaches the desired temperature. To achieve proper freezing, the product must be exposed to low temperatures for a short but sufficient period of time. As the temperature of the product drops, its liquid components transform into a solid state. Rapid freezing can halt any oxidative changes in the ingredients, prevent bacterial growth, and preserve the product\u2019s freshness. If the freezing process is slow, ice crystals form inside the product \u2014 which can negatively affect its texture and quality.<\/p>\r\n<ul>\r\n\t<li>Why choose it<\/li>\r\n<\/ul>\r\n<p>Deep freezing products \u2014 whether at their initial stage or in their final form \u2014 helps the business in many ways. Freezing methods in bakeries are used to schedule night shifts, provide flexibility in production planning, and ensure the availability of ready-made products for sale and delivery. It also helps the business prepare for upcoming holidays, festive periods, and days when an increase in demand for specific products is expected.<\/p>\r\n<ul>\r\n\t<li>Freezing bakery and pastry products<\/li>\r\n<\/ul>\r\n<p>The freezing process for breads and pastry items is an ideal choice.<br \/>\r\nThe freezing of ready-made and semi-prepared doughs today offers excellent opportunities for efficient and cost-effective production.<br \/>\r\nIt also allows products to be transported over long distances (for example, in the case of a chain of stores) while maintaining their exceptional quality. <em>The products that are typically frozen include<\/em>: unbaked products \u2014 sweet and savory bakery items, semi-prepared bakery products such as tarts, puff pastries, tsourekia, etc., ready-made products such as ice creams, cakes, pastries, etc.<\/p>\r\n<ul>\r\n\t<li>What you need to consider<\/li>\r\n<\/ul>\r\n<p>Under freezing conditions, for plain white breads, yeast levels typically range from 1.3% to 1.8%; for other types of bread from 1.8% to 2.5%; and for small breads or products rich in fats and sugars from 3% to 8% respectively. The hydration level of bakery products should be reduced by 1% to 2% for all product types. For storing products in the freezer for more than <strong>7 days<\/strong>, a bread improver is required. Products with high concentrations of soluble substances such as sugars, salt, and fats depress the freezing point of the dough. As a result, longer freezing times or greater energy consumption may be needed to lower the product\u2019s temperature. Thus, certain types of products may require different freezing conditions and processes from others.<\/p>\r\n<p><em>At +7\u00b0C to \u20137\u00b0C, the likelihood of product quality deterioration is generally lower compared to room temperature.<\/em><br \/>\r\n<em>At \u201330\u00b0C to \u201340\u00b0C, deep-freeze storage takes place.<\/em><br \/>\r\n<em>It is necessary for products to reach this temperature to maintain their structure.<\/em><\/p>\r\n<ul>\r\n\t<li>Defrosting process<\/li>\r\n<\/ul>\r\n<p>The defrosting process must be smooth and not abrupt. Proper thawing requires more time and gradual exposure to temperature changes. Begin by transferring products from \u201330\u00b0C to \u201318\u00b0C into a +5\u00b0C environment for up to 24 hours. Finally, place them in the proofer at +20\u00b0C to +35\u00b0C until the dough is fully matured.<\/p>\r\n<p><strong>A key detail<\/strong>: All freezing procedures require proper planning.<br \/>\r\nThis helps keep frozen-food storage costs as low as possible.<\/p>\r\n<p><em>Dimitris Fragkogiannis<\/em><br \/>\r\n<em>Baking Technical Consultant, Loulis Mills \u2013
