A candidate preserved food made by salt-curing bitter gourd in India. Process research exists, but regional formulations and the endpoint for bitterness require separate verification.
A reader-facing overview for this entry is in preparation. What has been checked, and its sources, can be followed from the claim cards below.
Scope: A study that examined, using response surface methodology, the salt-curing of bitter gourd (karela), regarded in India as a traditional process
Note: The optimal-condition values are not recorded here, as the full text has not been read. The broader role as a 『苦味調味料』 (in translation: "bitter seasoning") remains unverified.
The source positions the salt-curing of bitter gourd as a major traditional preservation process in India, and examines blanching, brine concentration, and time using response surface methodology.
Limitations: Full text not read. Optimal values, direct sensory bitterness values, and reproducibility at home are not adopted.
The Findings section of the structured abstract states explicitly that the blanching treatment has a significant effect (p<0.001) on water loss (WL), weight reduction (WR), solid gain (SG), water activity, and hardness alike.
Limitations: Only significance is given; the effect size and direction cannot be determined without the tables in the full text.
Limits: In the Findings section's statement giving 「15%食塩水濃度・5時間浸漬・ブランチング5.26分」 (in translation: "15% brine concentration, 5-hour soaking, blanching 5.26 minutes") as the optimal condition, the source lists a physically unrealistic value of 800 degrees Celsius for the blanching temperature (blanching is ordinarily a heating process carried out below the boiling point of water). This is most likely a misprint in the original text itself (such as a dropped digit), but because the same value was reproduced twice via a fetched summary, it does not look like a simple retrieval error.
Limitations: This temperature value must not be used as numeric grounds for measurements.csv or a new claim until the original PDF has been checked directly. It is recorded only as a value under suspicion of inconsistency.
