The Mexican government has regulations that defines the types of aguamiel used in the production of pulque. NMX-V-022 (Banco de Normas Mexicanas) (1) outlines the requirements of sugar, gum protein and lactic acid content, with Type I aguamiel being the cleanest variety with the highest sugar content and Type II being of a slightly more acidic pH.

NMX-V-037 is the regulation that recognizes the differences between seed or starter pulque and that which is commercially produced (1).

Escalante (etal 2012) in the Handbook of plant-based fermented food and beverage technology (Chapter 43) outlines a more general nutritional content of aguamiel than that shown above with the main compounds being present in the aguamiel as being, (2)

  • 0.3 to 0.4 g 100/mL of all essential amino acids (with exception of methionine) 

Vitamins (mg 100/mL) 

  • 0.02 riboflavin
  • 0.06 thiamine
  • 0.45 niacin
  • 19.60 biotin
  • 21.64 p-aminobenzoic acid
  • 65.17 panthothenic acid
  • 22.98 pyridoxine
  • 9.0 ascorbic acid

Sugars (glucose, sucrose, fructose, fructo-oligosaccharides, and inulin) (content levels not given)

Minerals (mg 100/mL) 

  • 25 sodium 
  • 9 magnesium
  • 1.1iron 
  • 0.8 zinc 
  • 0.3 Copper
  • 0.3 manganese

From these figures it is easy to see that fresh agave sap is a very nutritious food stuff
