Physical & Chemical Testing

Food physical and chemical testing refers to the determination of food ingredients through physical and chemical testing. Food can be tested for density, refractive index, optical rotation, moisture, acidity, etc. Physical and chemical testing of food can help food manufacturers monitor and control various indicators in the production process, such as moisture, acidity, pH value, etc., so as to ensure the stability and quality of food. Physical and chemical testing can also evaluate the content of nutrients in food, such as protein, fat, carbohydrates, etc., to ensure that the food meets nutritional standards and meets the health needs of consumers. Therefore, it is necessary to conduct reliable physical and chemical testing on food.

Physical & Chemical Testing Classification

Moisture Content Test	Acidity and pH Determination
Method: drying method, Kjeldahl nitrogen determination method, water activity test, etc. Purpose: control the storage, shelf life and microbial growth of food.	Method: use pH meter or acid-base titration method. Purpose: evaluate the acidity of food to affect its flavor and preservation effect.
Calorie Value Determination	Fat Content Determination
Method: combustion method or approximate calculation method. Purpose: determine the energy content of food.	Method: Soxhlet extraction method, solvent extraction method, etc. Purpose: evaluate the type and amount of fat in food.
Carbohydrate Determination	Protein Content Test
Method: enzymatic method, chemical method, etc. Purpose: analyze the sugar components in food.	Method: Kjeldahl nitrogen determination method, colorimetry, etc. Purpose: determine the protein content and amino acid composition of food.
Mineral Analysis	Volatile Substance Analysis
Methods: Atomic absorption spectrometry, inductively coupled plasma emission spectrometry, etc. Purpose: To evaluate the mineral content in food, such as calcium, iron, zinc, etc.	Method: gas chromatography, mass spectrometry, etc. Purpose: to analyze the aroma components and flavor substances of food.
Color Determination	Sensory Evaluation
Method: colorimeter or spectrophotometer. Purpose: to evaluate the visual quality and attractiveness of food.	Purpose: to evaluate the flavor, taste, smell, etc. of food through blind testing.

Why Physical and Chemical Tests?

With the development of social economy, people pay more and more attention to the nutritional content of food. Countries around the world have formulated food testing standards or regulations. Therefore, accurate food analysis is of great significance to ensure food quality and compliance with relevant standards.

Testing Food Quality: Physical and chemical tests can evaluate the quality of food, such as nutritional content, additive content, shelf life, etc., to ensure that food meets relevant standards.
Meeting Regulatory Requirements: Many countries and regions have strict laws and regulations on food safety and quality. Physical and chemical tests can help companies comply with these regulations and avoid penalties for non-compliance.
Improving Consumer Trust: Regular physical and chemical tests can improve consumers' trust in the brand and prove that the company attaches importance to product quality.
Product Development and Improvement: In the process of developing new products, physical and chemical tests can help the R&D team understand the physical and chemical properties of food, thereby optimizing the formula and process and improving the market competitiveness of the product.
