Gas Chromatography is not typically used for determining moisture content in food. Karl Fischer Titration, Gravimetric Analysis, and Nuclear Magnetic Resonance (NMR) are commonly used methods.

pH is primarily used to measure the acidity or alkalinity of food, which is important for understanding its flavor, texture, and microbial stability.

Gas Chromatography-Mass Spectrometry (GC-MS) is widely used for identifying and quantifying specific compounds in food, due to its high sensitivity and ability to separate and analyze complex mixtures.

Proximate analysis is a fundamental technique in food analysis, used to determine the moisture, protein, fat, ash, and carbohydrate content of food, providing insights into its nutritional composition.

Soxhlet Extraction is a widely used method for determining the fat content of food, involving the extraction of fats using a suitable solvent.

The Kjeldahl Method involves converting nitrogen in food to ammonia, which is then titrated to determine the nitrogen content.

Water Activity Meter is specifically designed to measure the water activity of food, which is a critical factor in determining microbial growth and stability.

Ash analysis involves incinerating food at high temperatures to determine its mineral content, providing insights into the nutritional value and quality of the food.

Spectrophotometry is commonly used for determining the vitamin C content of food, as it allows for the quantification of vitamin C based on its absorbance at a specific wavelength.

Sensory evaluation involves the use of human senses to assess the flavor, texture, and appearance of food, providing insights into consumer preferences and overall quality.

Microbial Culturing and Plating is a fundamental technique for measuring the microbial contamination of food, involving the growth and enumeration of microorganisms on suitable culture media.

Food safety audits are conducted to assess compliance with regulations, evaluate the effectiveness of management systems, and identify potential hazards and risks, ensuring the safety and quality of food products.

Gas Chromatography-Mass Spectrometry (GC-MS) is widely used for determining pesticide residues in food, due to its high sensitivity and ability to separate and identify complex mixtures of compounds.

Food labeling plays a crucial role in providing consumers with accurate and transparent information about the nutritional content, ingredients, and other relevant details of food products.

Spectrophotometry is commonly used for measuring the antioxidant activity of food, as it allows for the quantification of antioxidant compounds based on their absorbance at specific wavelengths.
