Description
Investigations were conducted on the effect of sugar concentration, pH balance and high methoxy pectin concentration on quality characteristics of pineapple jam using standard analytical methods. Addition of 50% sugar improved the colour and texture of the jam. Non-sugar jam was too soft, and could not hold their form. The jam balanced to pH 3.2 and 3.5 with the addition of lemon juice as a source of acid was of acceptable finished pH. Jam colour was not greatly affected by the incorporation of lemon juice. Addition of pectin had no significant effect on the pH of the finished jam. Sufficient pectin levels (0.5%) however improved the texture, gel formation and enhanced spreadability of the jam. Non-pectin jam was hard, tough and stiff and this was more evident in the 100% sugar with no pectin jam formulations. At 1.0% pectin concentration, spreadability of the jam was poor and colour became redder. Sensory …
