Gajar, A.M. | Badrie, N.
Effects of high methoxyl pectin (2% HM) and low methoxyl pectin (1.0, 2.0% LM) and carrageenan (0.03, 0.06, 0.09%) on gel set and texture were investigated in the production of a low-calorie (13g /1tbsp jam of < 10 calories) christophene (Sechium edule (Jacq.) jam. Inclusion of aspartame, saccharin with aspartame, and sucralose in jam provided sweetness and bulkiness while saccharin contributed to sweetness. Pectin had no effect (P>0.05) on texture but provided gel set (P < 0.05). A jam of 12 degrees Brix, pH 3.62, 2% HM pectin, 0.03% carrageenan, with 1.9% sucralose was "liked moderately" to "very much". Based on ranking, sucralose was most preferred (P < 0.05) over other sweeteners. Sensory texture of jam improved on storage at 7 degrees C but with loss (P < 0.05) of total soluble solids and significant fading (P < 0.05) of color by day 35.
