The Critical Impact of Water Quality on End Products in the Food & Beverage Industry

In the food and beverage industry, water is not just a raw material; it is the foundation, the solvent, and often the ‘soul’ of a product. From a perfect glass of beer to the deliciousness of broth, water quality directly reflects the quality of the final product. Ignoring it means jeopardising consistency, taste, and brand reputation.

This article will reveal how water parameters such as TDS, chloride, and taste subtly yet powerfully influence your products, and why investing in water polishing is not an option, but a necessity.

Water: The Secret Ingredient That Determines Product Excellence

While recipes and processing techniques are important, water makes up the largest percentage of many products. Inconsistencies in water quality can alter taste, aroma, texture, and even shelf life. Understanding the role of each key parameter is the first step towards superior production.

Key Parameters and Their Impact on Products

1. Total Dissolved Solids (TDS): Character Creator and Consistency Destroyer

TDS represents the total dissolved minerals such as calcium, magnesium, chloride, Fe and bicarbonate in water.

  • Impact on Beverages (Beer & Soda):

    • Soda & Soft Drinks: High TDS can disrupt the balance of sweetness and acidity, making the taste of the beverage ‘dull’ or unclear. The presence of certain minerals can also cause haze.

  • Impact on Processed Foods:

    • High TDS, particularly calcium and magnesium, can affect the texture of products such as tofu, bread, and processed meats. These minerals alter the way proteins and starches interact with water, resulting in a hard or uneven texture.

2. Chloride: A Hidden Cause of Saltiness and Corrosion

Chloride is an ion that is naturally present in water

  • Impact on Taste: Chloride provides an undesirable ‘salty’ or ‘briny’ sensation. In beverages such as soda or beer, slightly higher chloride levels can upset the flavour balance, making them taste salty or off-flavoured. In broths or soups, chloride can interfere with the balance of precisely crafted seasonings.

  • Impact on Corrosion & Shelf Life: Chloride is a highly aggressive corrosion trigger. At high concentrations, it can cause corrosion in stainless steel process lines and storage tanks. This not only causes costly equipment damage, but can also contaminate products with heavy metals such as chromium and nickel, which then shortens shelf life and poses a food safety risk.

3. Taste & Odour of Water: Must Be Clean

The water used must be a neutral canvas. Off-flavours and odours such as chlorine, earth, or sulphur will be directly transferred to the final product.

  • Soft Drinks & Bottled Water: Impurities in the water will be immediately detected by consumers, ruining the drinking experience and creating a negative perception of the brand.

Solution: Water Polishing - Final Stage Refinement for Highest Quality

Commonly Used Water Polishing Technologies:

  1. Activated Carbon: Highly effective at removing chlorine, odour-causing compounds, and organic colour. This is an important step to ensure a neutral flavour canvas.

  2. Ion Exchange: Used to further ‘soften’ water or remove specific ions such as nitrates and sulphates with high precision, enabling consistent mineral profiling.

  3. Reverse Osmosis (RO) and Electrodeionisation (EDI): These technologies produce water of extremely high purity (demineralised water). RO/EDI is often the backbone of modern water polishing, providing a clean and consistent base that can then be ‘reshaped’ by adding specific minerals as required by the product (remineralisation).

Conclusion: Quality Water is a Business Strategy

In competitive industries such as food and beverages, excellence often lies in the details. Water quality is one such critical detail.

By controlling parameters such as TDS, chloride, and taste, companies can:

  • Maintain Taste Consistency from batch to batch.

  • Protect Brand Integrity from consumer complaints and product failures.

  • Improve Production Efficiency by reducing equipment damage and batch rejections.

  • Innovate with Precision, creating new products with reliable flavour profiles.

Investing in the right water polishing system is not an operational cost, but a strategic investment in quality, reputation, and long-term profitability. Consult with water treatment experts to design a system that aligns with your standards and product characteristics.
