Moving on to next goo re-creation experiment. This one will test too litlle/much of pickling lime and citric acid, also 250ppm tap water will be used instead of distilled water.
Two 30g paste batches, one with 10% of scaled pickling lime, the other with double the scaled amount; each batch pulled as normal with scaled amounts of fresh EA; combined pulls from each batch split 6 ways: 3 to be actively crystallized, 3 to be passively crystallized; three levels of citric acid: 10% of scaled 5g dosage, scaled 5g dosage, 400% of scaled 5g dosage.
Specifically:
Cactus powder - 30g/ batch
Pickling lime - Batch A 0.75g, Batch B 15g
250ppm tap
: 90mL per batch
8 minute stir, fold, mash
10 minute rest
6 x 3 minute standard pulls; fresh EA: 1st pull 71mL, pulls 2-6 43mL; each pull coffee filtered, combined pulls rested 1hr, then split into 6 equal portions per batch
For each batch, 3 portions will be actively magnetic stirred (sub-batch 1) for 10 minutes, then rested for 24hrs before filtering; 3 portions will be passively crystallized (sub-batch 0) for 48 hrs before filtering. Each 3-portion sub-batch will be individually dosed with either 0.03g (X), 0.25g (Y), or 1.00g (Z).
2/2:
Processing Observations:
Batch A - paste became sticky pudding-/guacamole-like during mixing, stayed that way until becoming sticky snot-like first to last pulls; first 2 pulls very light, almost yellow hue, darkening on pull 3, combined pulls somewhat lighter than normal; solvent recovery about 70%; combined pulls pH 9-10.
Batch B - paste became somewhat drier and more crumbly than my usual cookie dough/playdough during mixing, stayed that way until pulling, when it eventually became somewhat more runny and finer grained than my normal applesauce consistency by last pull; hue substantially darker than normal for first 4 pulls, then lightening in 5th & 6th pulls, combined pulls substantially darker than normal; solvent recovery about 80%; combined pulls pH 9-10.
Salting proceeded as normal: all active jars clouded during magnetic stirring and precipitated shortly afterwards; all passive jars clouded, and later were crystallizing as normal.
2/3: The six active crystallization treatments, for both levels of lime and three levels of citrate, have been filtered. The jars will be washed and evap’d, with yields (fwiw) posted later. All jars produced white powder product as is normal for this crystallization method. Nothing that could be called “goo” was produced.
2/5: Got delayed. The passive crystallization jars were filtered today, none had goo.
Also, weighed all filtrate samples, as follows:
Low Lime. Active Crystallization: low citrate 0.038g, standard citrate 0.040g, high citrate 0.046g
Low Lime, Passive Crystallization: low citrate 0.071, standard citrate 0.068g, high citrate ?0.029g?
High Lime, Active Crystallization: low citrate 0.048g, standard citrate 0.042g, high citrate 0.038
High Lime, Passive Crystallization: low citrate 0.070g, standard citrate 0.069g, high citrate 0.071g
2/6: Jar washes evaporated, final yields:
Low Lime. Active Crystallization: low citrate 0.045g, standard citrate 0.047g, high citrate 0.047g
Low Lime, Passive Crystallization: low citrate 0.077g, standard citrate 0.0.076g, high citrate ?0.043g?
High Lime, Active Crystallization: low citrate 0.052g, standard citrate 0.051g, high citrate 0.047g
High Lime, Passive Crystallization: low citrate 0.076g, standard citrate 0.070g, high citrate 0.087g
Conclusions:
Goo production is not simply due to too little/much of lime or citric acid.
Low Lime adversely impacts yield, high lime may have marginal positive impact on yield, if any.
Citrate level above 0.6% of cactus powder weight has little to no effect on yield.
