A small-scale, 24-run experiment to evaluate standard process vs treatment options, using 3 salting/crystallization methods.
Using a single powdered material, which vendor describes as “San Pedro Ecuador, T. pachanoi…100% flesh, no spines, no core”.
Salting/Crystallization Methods:
A. Low Citric, Passive Crystallization: 0.75g citric acid, single stir, 56 hour rest
B. Low Citric, Active Crystallization: 0.75g citric acid, 20 minute magnetic stirring, 24 hour rest
C. High Citric, Active Crystallization: 2.25g citric acid, 20 minute magnetic stirring, 24 hour rest
Treatments (refer to detailed method in posts 497 & 566):
I,0,0,0,1 - individual paste, wet mixed, no microwave, no chilling, each run stirred 1 minute then rested 2 minutes
B,0,0,0,1 - bulk paste, wet mixed, no microwave, no chilling, each run stirred 1 minute then rested 2 minutes
B,1,0,0,1 - bulk paste, dry mixed, no microwave, no chilling, each run stirred 1 minute then rested 2 minutes
B,0,1,0,1 - bulk paste, wet mixed, microwaved paste, no chilling, each run stirred 1 minute then rested 2 minutes
B,0,0,1,0 - bulk paste, wet mixed, no microwave, chilled solvent & paste, each run stirred 1 minute but not rested
B,0,0,1,1 - bulk paste, wet mixed, no microwave, chilled solvent & paste, each run stirred 1 minute then rested 2 minutes
B,0,1,1,0 - bulk paste, wet mixed, microwaved paste, chilled solvent & paste, each run stirred 1 minute but not rested
B,0,1,1,1 - bulk paste, wet mixed, microwaved paste, chilled solvent & paste, each run stirred 1 minute then rested 2 minutes
The first 3 treatments are slight variations of what I refer to as the “standard process”, involving slight changes in the initial preparation of the paste ingredients.
Individual Paste: paste runs made from individual 15g batches of material
Bulk Paste: paste runs made from 45g batches of material, divided into 3 equal-weight runs after 10 minute rest or after microwaving in the case of microwaved treatments
Wet mix paste: mix lime & water, them mix powder in for 8 minutes, let rest 10 minutes
Dry mix paste: mix lime and powder, then mix water in for 8 minutes, let rest 10 minutes
Microwaved paste: after resting paste, microwave paste until 2/3 of added water has evaporated
Chilled solvent & paste: prior to pulling, chill solvent in freezer for 24 hours, chill paste in fridge for 24 hours
Bulk Batch Ingredients:
Material - 45g (~9% moisture content)
Pickling lime - 11.25g (~3% moisture content)
Distilled water - 135mL
Individual Batch Ingredients:
Material - 15g (~9% moisture content)
Pickling lime - 3.75g (~3% moisture content)
Distilled water - 45g
Fresh ethyl acetate volume per pull:
1st pull - 30mL
Pulls 2 to 6 - 22 mL each
Results:
The 1st pic shows representative samples of products produced in all runs, using salting methods A, B, C. Each product from each run was also tasted, from a flavor/perception perspective all product, regardless of pastemaking, pulling, and salting treatment, “tastes” identical, with moderate bitterness and absolutely zero acidity.
The 2nd pic shows the yield results of each run.
Key Points:
1. Comparing (I,0,0,0,1) vs (B,0,0,0,1): Bulk paste preparation and division into equal-sized portions, provides the same or slightly better yield than individual preparation of portions that are the same size as subdivided bulk portions.
2. Comparing (B,0,0,0,1) vs (B,1,0,0,1): Wet mixing or dry mixing of standard process paste provides no meaningful difference in yield.
3. Comparing standard process (I,0,0,01), (B,0,0,0,1), (B,1,0,0,1) vs all other treatments: The standard process provides the same or higher yield than any of the other treatments (which involve additional processing steps).
4. Comparing (B,0,0,1,0) vs (B,0,0,1,1) and (B,0,1,1,0) vs (B,0,1,1,1): Adding a 2 minute resting period after 1 minute of mixing, per pull, provides the same or better yields, particularly when using magnetic stirring.
5. Comparing Salting/Crystallization methods A, B, C: Except for chilled treatments with a 2 minute rest period, passive vs active stirring makes little difference in yield. Additionally, the high citric acid active stirring treatment provided no addition yield vs the low acid active stirring treatment.
