In the global market of edible oils, cold-pressed non-GMO soybean oil has emerged as a popular choice among food enterprises and importers. But how can one scientifically evaluate its quality? This article delves into the core significance of two key quality indicators: acid value (≤0.2 mg KOH/g) and peroxide value (≤5.0 meq/kg), and their crucial impact on oil freshness, thermal stability, and food safety.
The acid value of oil reflects the amount of free fatty acids present. A lower acid value indicates better oil quality and freshness. The peroxide value, on the other hand, measures the level of primary oxidation products in the oil. High peroxide values can lead to off-flavors and reduced nutritional value.
The detection methods for these two indicators are well - established. For acid value, titration is commonly used, while iodometric titration is the standard method for peroxide value. Different industries may have slightly different standards for these values. For example, in the food industry, stricter standards are often applied to ensure consumer safety.
Acid Value and Peroxide Value Ranges
| Indicator | Ideal Range |
|---|---|
| Acid Value | ≤0.2 mg KOH/g |
| Peroxide Value | ≤5.0 meq/kg |
These indicators are direct reflections of oil freshness. Fresh cold - pressed non - GMO soybean oil typically has low acid and peroxide values. In terms of antioxidant capacity, oils with lower values are more resistant to oxidation, which means they can maintain their quality for a longer time.
Compared with traditional hot - pressed oils, cold - pressed oils have significant advantages. Hot - pressed oils often have higher acid and peroxide values due to the high - temperature processing, which can also lead to the loss of some nutrients. For example, a study showed that the acid value of hot - pressed soybean oil was on average 0.5 mg KOH/g, while that of cold - pressed oil was only 0.15 mg KOH/g.
International certifications such as ISO22000 and HACCP play a vital role in supply chain management. ISO22000 focuses on food safety management systems, ensuring that products meet international food safety standards. HACCP, on the other hand, is a systematic preventive approach to food safety that identifies, evaluates, and controls hazards.
"ISO22000 requires organizations to establish, implement, maintain, and continuously improve a food safety management system..."
These certifications have a significant impact on global customers' purchasing decisions. A product with these certifications gives buyers more confidence in the product's quality and safety. For example, a European food importer reported that they were more likely to choose suppliers with ISO22000 and HACCP certifications, as it reduced the risk of food safety issues.
Each batch of cold - pressed non - GMO soybean oil has a traceability system, which allows buyers to track the origin of the oil from the source to the table. This ensures that every step of the supply chain is controllable, making each purchase more reassuring.
The packaging of the oil also comes in a variety of sizes, from 500mL to 5L, which can meet different usage scenarios. For example, small - sized packages are suitable for households, while large - sized packages are more appropriate for food service providers.
To help buyers make more informed decisions, here is a practical procurement list template:
Procurement List Template
| Item | Requirement |
|---|---|
| Acid Value | ≤0.2 mg KOH/g |
| Peroxide Value | ≤5.0 meq/kg |
| Certifications | ISO22000, HACCP |
| Traceability | Available |
In addition, understanding how to read SGS/BV detection reports can also enhance buyers' confidence in their purchases. For example, by checking the acid and peroxide values in the report, buyers can quickly assess the product's quality.
In the context of the global trend towards healthy eating, cold - pressed non - GMO soybean oil has strong market competitiveness. Its low acid and peroxide values, along with international certifications and traceability systems, ensure compliance with various international regulations.
