Influence of Storage on Some Physicochemical and Microbial Properties of Concentrates from Two Sudanese Mangos (Mangifera indica) Verities | Chapter 11 | Current Trends in Food Science Vol. 1
Aims:
To produce concentrates at remote areas of production, where fruits are
expected to be cheaper and hence compete with imported concentrates.
Study Design: Factorial Experimental
design.
Place and Duration of Study:
Department of Food Science and Technology, Faculty of Agriculture, University
of Khartoum, Sudan and Food Research Center, Shambat, Sudan, between September
2009 and May 2010.
Methodology: Two mango (Mangifera
indica) varieties Abu Samaka and Baladi were used to produce concentrate and
the concentrate was stored at ambient temperature and a refrigerator at 4ºC for
6 months. The concentrates were prepared by using open kettle boiler (100ºC)
and they were packed in cans using double seam machine.
Results: The Baladi variety gave
higher total soluble solids (TSS) than Abu Samaka. Abu Samaka exhibited an
excellent percentage (29.7%) of total sugars during storage and the total
titrable acidity of mango concentrate in the two varieties reported a slightly
increase. The reducing sugars increased gradually with storage time. The two
varieties showed retention of ascorbic acid content during storage. There was
no growth of E. coli, yeast and molds in the concentrates of the two varieties
tell the end of the storage period (6 months). The concentrates from the two
varieties at both temperatures were acceptable by the panelists.
Conclusion: The two varieties showed
suitability in processing to give mango concentrate.
