Other claims from this paper (12)
- Intervention effect Addition of chloride decreased the nitrate uptake of the tomatoes.
- Intervention effect Chloride addition significantly reduced detinning in plain cans.
- Association Detinning correlated positively with a high nitrate, high chloride nutrient regime after 27 months storage, attributed to higher total acid in the juices.
- Association Delamination with underfilm corrosion in lacquered cans was correlated with tomatoes grown under a higher nitrate, medium chloride regime.
- Intervention effect Tomatoes grown under a higher nitrate, low chloride regime had nitrate concentrations as high as 1.0 mmol/litre and high corrosivity.
- Intervention effect Tomatoes grown under low nitrate and increasing chloride gave juices with nitrate as low as 0.18 mmol/litre.
- Intervention effect Under low nitrate and increasing chloride regimes, juices had higher chloride concentrations up to 42 mmol/litre.
- Observation No delamination was observed in lacquered cans of juices from tomatoes grown under low nitrate and increasing chloride.
- Observation Some pitting corrosion and perforations occurred in lacquered cans of these juices at the end of 27 months at 36 C.
- Association Ascorbic acid retention was mainly correlated with can type and the initial ascorbic acid level of the raw tomatoes, which resulted from Cl and NO3 interaction in the nutrient solution.
- Intervention effect At 22 C over 27 months, ascorbic acid retention was higher in plain tinplate cans (88%) than in lacquered cans (24%).
- Intervention effect At 36 C over 27 months, ascorbic acid retention was higher in plain tinplate cans (70%) than in lacquered cans (18%).
