Oat milk

Flavor Lab recipy

Flavor Lab published a video explaining that industrial oat milk (like Oatly) is sweet due use of amylase enzyme that breaks starch into sugar.

Ingredients:

• 1 cup (80 g) of rolled oats
• 6 cups (1.4 l) of water
• 5 g amylase (around 1 teaspoon)

Recipe:

1. cook rolled oats until grains are soft. This releases the starch (gelatinization process).
2. cool it down to 72-75°C range
3. add amylase
4. let this sit from 20 min to 1 hour.
5. blend
6. squeeze on nut bag
7. cool it down on fridge

The video description has a link to this amylase ad. It is a 43 g bottle and it says on its label:

Starch conversion aid - Use 0.1 - 0.3 teaspoons per gallon (4.54 l) to convert starches into fermentable sugars.

Oat milk study

Babolanimogadam N, Gandomi H, Akhondzadeh Basti A, Taherzadeh MJ. Nutritional, functional, and sensorial properties of oat milk produced by single and combined acid, alkaline, α-amylase, and sprouting treatments. Food Sci Nutr. 2022 Dec 8;11(5):2288-2297. doi: 10.1002/fsn3.3171. PMID: 37181303; PMCID: PMC10171527. Available at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10171527/

In this study, the effects of different treatments of the oat slurry on the nutritional, functional, and sensorial properties of oat milk were evaluated.

For all treatments, 500 ml of distilled water was added to 100 g milled oat in 1‐L bottles. In addition, 200 mg of α‐amylase was employed for enzyme treatment (En) and heating for 60 min at 65°C.

This corresponds to less than 400 mg of enzyme per liter of oat milk (assuming 1 l of water plus 200 g of oats will yield more than 1 l of oat milk).

The En treatment showed the highest color and aroma scores (8.2 and 8.1, respectively), and the sprouting treatment showed the highest flavor score (7.6). Furthermore, the overall acceptability score of enzyme and sprouting–enzyme treatments was the highest (7.9).

Prodooze

Prodooze is a brand of products for home-brew. It has the technical file of the Prodooze Alfa-Amilase available online.

• Na mosturação de adjuntos: Dosar no cozinhador antes do cozimento. Dosagem: entre 100 e 600 ml enzima/ton de adjunto. A Prodooze ALFA tem temperatura ótima de 80- 90°C, mas mantém cerca de 80% de sua atividade máxima a 75°C.

• Na mosturação do malte: Dosar a qualquer momento da mostura; a atividade será maximizada quanto maior for o tempo de contato com o mosto. Dosagem 50 a 200 ml enzima/ton de cereais (malte + adjuntos)

This ad converts the use instructions to lower volumes. It says:

• Na mosturação de adjuntos: Dosar no cozinhador antes do cozimento. Dosagem: entre 2 e 12 gotas enzima por kg de adjunto. A Prodooze ALFA tem temperatura ótima de 80- 90°C, mas mantém cerca de 80% de sua atividade máxima a 75°C.

• Na mosturação do malte: Dosar a qualquer momento da mostura; a atividade será maximizada quanto maior for o tempo de contato com o mosto. Dosagem 1 a 4 gotas enzima por kg de cereais (malte + adjuntos)

So it considered that 1 drop correspond to 50 mg. This matches the label, which says the dose is 0.05 - 0.2 g/kg (i.e., 50 - 200 mg/kg).

A typical drop of water from a standard dropper is often considered to be around 0.05 to 0.1 ml.
