What is a double-blind experiment in nutritional studies?

Both the subjects and the researchers do not know which subjects are in which group.

Grams of sucrose per 100g of sample is the definition of what?

Brix

Which standard is used to calibrate pH meters?

Buffer solutions.

How are free fatty acids usually measured?

By titration with NaOH

The Beer-Lambert Law is A= ECL; what does the 'C' stand for?

C is concentration in moles/L

What is the Molisch test used for?

Carbohydrates. It detects the presence of all carbohydrates (monosaccharides, disaccharides, and polysaccharides) by dehydrating them with sulfuric acid to form furfural derivatives, which then react with α-naphthol to produce a violet or purple ring.

What protein is used as a reference to measure the Protein Digestibility Corrected Amino Acid Ratio?

Casein

What does COD stand for regarding measuring organic compounds in water?

Chemical Oxygen Demand

What are Mohr's titration and Volhard titration used for?

Chloride ion concentration (indirectly salt concentration)

Which analytical technique separates compounds based on differential partitioning between stationary and mobile phases?

Chromatography

CRISPR stands for?

Clustered regularly interspaced short palindromic repeats (enzyme used is cas9)

CMC is a subgroup of the society of Dyers and Colorists of great britain. This subgroup is the organization that developed and published in 1988 a more logical, ellipse-based equation based on L*C*h˚ color space for computing DE (see delta E*) values as an alternative to the rectangular coordinates of the CIELAB color space.What does CMC stand for?

Color Measurement Committee

What type of method is the phenol sulfuric acid value, and what does this assay determine?

Colorimetric, total carbohydrates

Which technique measures the color of food using L*, a*, and b* values?

Colorimetry (CIE Lab color system)

What type of spectroscopy is commonly used to determine food color values (L*, a*, b*)?

Colorimetry using a HunterLab or Minolta colorimeter
