Abstract

Non-thermal two-stage microfiltration technique in aseptic conditions was used to preserve coconut water. Concentrations of citric acid (0.02 g/100 mL), ascorbic acid (0.18 g/100 mL) and l-cysteine (0.009 g/100 mL) were standardized according to taste and added to coconut water as natural additives. The coconut water was packed in glass and plastic bottles after flushing the headspace with nitrogen and stored under refrigeration (4 °C). The microfiltered water was studied for microbial, sensory and physicochemical properties for a period of 46 days. The quality of the water packed in glass bottles was better in all respects. The total soluble solids changed from 5.4 to 6 °Brix. The pH changed from 5.7 to 5.8. The soluble sugar concentration increased from 1.9 g/100 mL to 3.1 g/100 mL, free fatty acid content increased from 0.064 mg KOH/g to 2.8 mg KOH/g at the end of 46 days, which was much lower than the changes in control. The protein content decreased in all the samples. Two way ANOVA showed that the storage time had more impact on the sensory properties of the product than the packaging material. The glass bottled product was acceptable on sensory basis till 46 days of storage.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
