From the selection of raw materials to their transformation into consumer-ready products, every stage requires meticulous <strong>control<\/strong>. Ensuring that food is safe, nutritious, and of high quality is no accident: it is the result of rigorous procedures that include the detailed study of its properties. In this context, <strong>physicochemical analyses<\/strong> are essential tools for food production.<\/p>\n<p>At <strong>Cosmos Arom\u00e1tica<\/strong>, we work on the design and production of <strong>flavourings and aromatic solutions for the food industry<\/strong>, collaborating with R&amp;D, quality, and production teams to develop stable, reproducible profiles adapted to each matrix and process. Throughout this article, we explain the purpose of <strong>physicochemical analyses<\/strong> and their importance in food production.<\/p>\n<h2><strong>Why physicochemical analyses are critical in a food plant<\/strong><\/h2>\n<p><strong>Physicochemical analyses<\/strong> are integrated into a control system that helps to <strong>maintain the product<\/strong> within specification and to <strong>reduce operational risks<\/strong>. When a batch deviates, it is rarely due to a single cause: it could be a variable raw material, a change in temperature, insufficient mixing, a shorter drying stage, fermentation progressing faster than planned, or packaging that does not provide the same level of protection.<\/p>\n<p><strong>Physicochemical analyses<\/strong> provide three clear advantages:<\/p>\n<ul>\n<li aria-level=\"1\"><strong>Process control<\/strong>: detecting deviations before they turn into rejections, reworks, or downtime.<\/li>\n<li aria-level=\"1\"><strong>Raw material control<\/strong>: managing variations and adjusting formulations or process conditions with sound judgment.<\/li>\n<li aria-level=\"1\"><strong>Technical evidence<\/strong>: documenting compliance with internal and client requirements, with full traceability.<\/li>\n<\/ul>\n<h2><strong>What objectives do physicochemical analyses pursue?<\/strong><\/h2>\n<p>The objectives can be organised in a practical way, keeping the day-to-day factory operations in mind. In all of them, <strong>physicochemical analyses<\/strong> act as sensors that translate what is happening in the process into comparable figures.<\/p>\n<h3><strong>Ensuring stability and shelf life<\/strong><\/h3>\n<p>Many shelf-life problems are anticipated using parameters such as <strong>water activity, moisture, pH, acidity, peroxide value in fats, or colour changes<\/strong>. If a parameter drifts from batch to batch, something in the process is changing.<\/p>\n<h3><strong>Maintaining consistent sensory quality<\/strong><\/h3>\n<p><strong>Texture, succulence, crunchiness, stable emulsion, or the absence of phase separation<\/strong> are usually connected to measurable variables: fat content, protein, soluble solids, viscosity, particle size, or water-holding capacity. Physicochemical analyses allow <strong>perceivable characteristics<\/strong> to be linked with the <strong>parameters that can be modified<\/strong>.<\/p>\n<h3><strong>Reducing waste and reworks<\/strong><\/h3>\n<p>Precise control of the end point of each stage makes it possible to <strong>avoid exceeding or falling short of the desired target<\/strong>. For example, insufficient drying can increase moisture and trigger subsequent incidents; excessive thermal treatment can affect colour or functionality. Measuring accurately avoids correcting too late.<\/p>\n<h3><strong>Verifying technological functionality<\/strong><\/h3>\n<p>In food production, many raw materials are chosen for their <strong>function<\/strong>: to emulsify, gel, thicken, stabilise foam, or provide structure. Physicochemical and rheological tests help to <strong>check<\/strong> if that functionality is maintained across different suppliers, batches, and real-world conditions.<\/p>\n<h3><strong>Supporting continuous improvement<\/strong><\/h3>\n<p>Data opens the door to <strong>optimisation<\/strong>: adjusting times, temperatures, addition order, stirring speed, homogenisation pressure, or intermediate storage conditions. With historical series, <strong>physicochemical analyses<\/strong> allow a distinction to be made between normal variation and a real process change.<\/p>\n<h2><strong>Where they are applied in the production flow<\/strong><\/h2>\n<p>Typical control points are usually located in:<\/p>\n<h3><strong>Raw materials intake<\/strong><\/h3>\n<p>The aim here is to <strong>confirm identity, condition, and variability<\/strong>: moisture, fat, protein, pH, ash, density, soluble solids, or functional properties as appropriate. Good reception control prevents the problem from entering the line.<\/p>\n<h3><strong>In-process control<\/strong><\/h3>\n<p><strong>Rapid measurements<\/strong> on the line or in the plant laboratory to decide whether to proceed to the next stage: pH in fermentation, soluble solids during concentration, viscosity in mixtures, salinity, conductivity, or moisture control during drying.<\/p>\n<h3><strong>Finished product release<\/strong><\/h3>\n<p><strong>Final verification<\/strong> of internal specifications and client requirements. In many cases, the analytical data is combined with sensory controls, weight, sealing, and documented operational parameters.<\/p>\n<h2><strong>What are the basic parameters in a physicochemical analysis?<\/strong><\/h2>\n<p>Although each food category has its own particularities, there is a set of<a href=\"https:\/\/www.aoac.org\/official-methods-of-analysis\/\" target=\"_blank\" rel=\"noopener\"> <strong>base parameters<\/strong><\/a> that appear in most plants.<\/p>\n<h3><strong>Moisture and dry matter<\/strong><\/h3>\n<p><strong>What it indicates<\/strong>: Water availability in the product and, in many cases, stability. <strong>Why it matters in production<\/strong>: It affects texture, yield, cost per kilo, stability, and storage behaviour. <strong>Process notes<\/strong>: Changes in drying, baking times, evaporation, or absorption can be quickly reflected here.<\/p>\n<h3><strong>Water activity (aw)<\/strong><\/h3>\n<p><strong>What it indicates<\/strong>: How much water is &#8220;free&#8221; for reactions and microbial growth (this is not the same as moisture). <strong>Why it matters<\/strong>: Stability, <a href=\"https:\/\/new.cosmosaromatica.com\/en\/microbiological-analysis-in-flavours-beverages-and-their-ingredients-control-quality-and-safety\/\"><strong>microbiological<\/strong><\/a> risk, and texture (for example, loss of crunchiness). <strong>Typical use<\/strong>: Snacks, bakery, dehydrated products, confectionery, products with a fat phase, and long-life foods.<\/p>\n<h3><strong>pH and acidity<\/strong><\/h3>\n<p><strong>What it indicates<\/strong>: Acid-base balance and, depending on the case, the progress of fermentation or the impact of ingredients. <strong>Why it matters<\/strong>: Safety, stability, flavour, and functionality of proteins or hydrocolloids. <strong>In the plant<\/strong>: It is used to control cut-off points in fermentation, formulation adjustments, or emulsion stability.<\/p>\n<h3><strong>Soluble solids (\u00b0Brix)<\/strong><\/h3>\n<p><strong>What it indicates<\/strong>: Approximate concentration of dissolved solutes (widely used in aqueous matrices). <strong>Why it matters<\/strong>: Consistency of syrups, <a href=\"https:\/\/new.cosmosaromatica.com\/sectores\/bebidas\/\"><strong>beverages<\/strong><\/a>, sauces, and concentrates; impact on perceived sweetness and viscosity. <strong>In process<\/strong>: Control of concentration, evaporation, or mixing.<\/p>\n<h3><strong>Fat, protein, and ash content<\/strong><\/h3>\n<p><strong>What they indicate<\/strong>: Basic composition and technological profile. <strong>Why they matter<\/strong>: Yield, nutritional value, functional behaviour, and batch consistency. <strong>In production<\/strong>: They help to adjust formulations, detect out-of-range raw materials, and maintain homogeneity.<\/p>\n<h3><strong>Salinity or chlorides<\/strong><\/h3>\n<p><strong>What it indicates<\/strong>: Salt level and, in some products, stability and flavour. <strong>Why it matters<\/strong>: Product standard, sensory perception, and process control (brine, curing, formulation).<\/p>\n<h3><strong>Colour (instrumental)<\/strong><\/h3>\n<p><strong>What it indicates<\/strong>: Changes due to oxidation, browning reactions, thermal treatment, or raw material variation. <strong>Why it matters<\/strong>: Client acceptance and visual consistency. <strong>In the plant<\/strong>: Useful for monitoring roasting, cooking, oxidation, or ingredient deviations.<\/p>\n<h3><strong>Viscosity and rheological behaviour<\/strong><\/h3>\n<p><strong>What it indicates<\/strong>: How the product flows and how it responds to mixing or pumping stress. <strong>Why it matters<\/strong>: Filling, stability, mouthfeel, and batch-to-batch consistency. <strong>In production<\/strong>: Highly relevant in sauces, creams, dairy products, thick beverages, or emulsions.<\/p>\n<h2><strong>What equipment is required to perform advanced physicochemical analyses?<\/strong><\/h2>\n<p>When basic control is not enough (due to client demands, process complexity, or the need to investigate causes), more advanced techniques and equipment appear.<\/p>\n<h3><strong>Instrumentation for rapid composition and characterisation<\/strong><\/h3>\n<h4><strong>Spectroscopy (e.g. NIR)<\/strong><\/h4>\n<p>Used for <strong>rapid estimations<\/strong> of composition parameters in certain matrices (moisture, fat, protein, or others, depending on calibrations). Its value lies in its speed and support for decision-making in reception and processing, provided calibrations are well maintained.<\/p>\n<h4><strong>Automatic moisture analysers<\/strong><\/h4>\n<p>When time is of the essence, rapid-reading equipment is used to support immediate adjustments in drying, baking, or mixing.<\/p>\n<h3><strong>Equipment for stability, texture, and structure<\/strong><\/h3>\n<h4><strong>Advanced rheometers and viscometers<\/strong><\/h4>\n<p>These allow an understanding of whether a product is <strong>pseudoplastic, thixotropic<\/strong>, or if its structure changes over time. This impacts pumping, mixing, filling, and final texture.<\/p>\n<h4><strong>Texture analysers<\/strong><\/h4>\n<p>They help to correlate process parameters with <strong>bite, firmness, elasticity, or fracture<\/strong>. In production, they can serve to standardise processes when sensory criteria are not enough.<\/p>\n<h3><strong>Equipment for fat and oxidation control<\/strong><\/h3>\n<h4><strong>Measurement of oxidation and fat stability<\/strong><\/h4>\n<p>Determinations related to oxidation are key in products with a <strong>fat phase<\/strong> (snacks, sauces, nuts, preparations). The industrial interest is to avoid rancidity and protect shelf life.<\/p>\n<h3><strong>Equipment for detailed separation and quantification<\/strong><\/h3>\n<h4><strong>Chromatography (GC\/HPLC)<\/strong><\/h4>\n<p>Used when it is necessary to <strong>separate and quantify compounds<\/strong>: fatty acid profiles, sugars, organic acids, volatile aroma compounds, or process markers. In production, it usually comes into play when confirming causes, comparing suppliers, or validating changes.<\/p>\n<h4><strong>Spectrometry (coupled according to the method)<\/strong><\/h4>\n<p>Applied in contexts where <strong>identification and quantification<\/strong> require high selectivity. Its use is common in laboratories with complex analytical needs.<\/p>\n<h3><strong>Infrastructure and technical support of the laboratory<\/strong><\/h3>\n<p>In addition to the &#8220;main&#8221; equipment, the reliability of <strong>physicochemical analyses<\/strong> depends on:<\/p>\n<ul>\n<li aria-level=\"1\">Internal calibrations and verifications.<\/li>\n<li aria-level=\"1\">Reagents and reference materials when the method requires them.<\/li>\n<li aria-level=\"1\">Suitable balances, temperature control, and good sampling practices.<\/li>\n<li aria-level=\"1\">Cleaning procedures and prevention of cross-contamination in the laboratory.<\/li>\n<\/ul>\n<h2><strong>Data that turns into control<\/strong><\/h2>\n<p><strong>Physicochemical analyses<\/strong> are a practical part of production control: they allow raw materials to be understood, critical stages to be monitored, the product to be kept within specification, and batch-to-batch quality to be sustained. When designed with real plant decisions in mind, they become an <strong>operational advantage<\/strong>: less variation, less rework, and more stability.<\/p>\n<p>To apply <strong>physicochemical analyses<\/strong> with a truly useful approach for production (reception, process, and release), at <strong>Cosmos Arom\u00e1tica<\/strong> we help you define which parameters make sense for your line and how to turn the results into clear control criteria. <a href=\"https:\/\/new.cosmosaromatica.com\/contacto\/\"><strong>Get in touch<\/strong><\/a> with us for a technical consultation, and we will review your case.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Every food that reaches our table goes through a long process before being consumed.
