ANTI-SAP CHEMICALS AND HOT WATER QUARANTINE TREATMENT EFFECTS ON STORAGE LIFE AND FRUIT QUALITY OF MANGO CV. SAMAR BAHISHT CHAUNSA
Bibliographic record
Abstract
This study aimed at testing the combined effects of anti-sap chemicals and hot water quarantine treatment (HWQT: 48°C-60min) on a commercial mango cv.Samar Bahisht (S.B.) Chaunsa, as potential protocol for export to China.The physiologically mature mango fruit were harvested along with 4-5 cm pedicel.After de-stemming, the fruits were treated with potential anti-sap chemicals: calcium hydroxide [Ca(OH) 2 ], potassium aluminium sulphate [KAl(SO 4 ) 2 .12(H 2 O)], Tween-80 [C 64 H 124 O 26 ].After chemical application, half of the fruit lot was subjected to HWQT as per protocol, while the remaining half was kept without HWQT.The fruit after treatments were air dried, packed in cardboard boxes and stored (13±1°C, 85% RH) for 21 days.Sapburn injuries were scored after 24, 48, 72 hrs and 21days of storage.After storage the fruit were allowed to ripe at room temperature and assessed for physical disorders and disease incidence.Fruit were also analysed for firmness, peel colour, sugars, titratable acidity, total carotenoids, ascorbic acid contents and organoleptic characteristics (pulp colour, texture, taste, aroma, flavour).Sapburn injury score showed significant differences for chemicals and chemical-HWQT interactions.De-stemming under lime [Ca (OH) 2 ] followed by HWQT showed least sapburn injury with more firm fruit.HW treated fruit showed significantly lower anthracnose disease incidence (1.68 vs 2.42), while higher sugars (18.32 vs 14.56%) with more pulp browning (0.74 vs 0.48) and higher total carotenoids (67.0 vs 56.1µg/g) compared to without HWQT.Organoleptic evaluation revealed smoother pulp texture in fruit without HWQT.It was concluded that mango desapping with 1.0% lime solution, followed by HWQT (48°C-60min), did not significantly impair quality during 21 days of storage, beside controlling sapburn injury and meeting market access requirement.However, in view of the exhibited heat induced effects, more studies are needed on HWQT effects on various maturity levels and improving post-storage colour development in mango cv.S.B. Chaunsa, for its export to China, by sea or road, using refrigerated containers.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
