Grape jellies

The grape jellies were made using the pectin concentrations of 0.5, 0.75, and 1% for the three types of essayed pectin.

Grape color extract is used to color such products as bakers jams, non-standard jellies and preserves, sherbets, ices, pops, raspberry, grape and strawberry yogurts, gelatin desserts, canned fmit, fmit sauces, candy and confections, and bakery fillings and toppiags. Typical use concentrations are 0.05 to 0.8%, based on the weight of the finished product. 

Production of hypocaloric jellies of grape juice with sunflower pectin... 

Following earlier studies about physico-chemical characterization of sunflower pectin (Alarc o-Silva, 1990 Leitao et al, 1995) and technological utilization in the manufacture of low-caloric gels (Alarcao-Silva et al, 1992), we intend with this contribution to study the behaviour of this pectin in the confection of grape juice jellies and the evaluation of their organoleptic characteristics. 

Following previous works on physico-chemical characterisation of sunflower low-methoxyl pectins (Alarc o-Silva, 1990, Leitao at al., 1995) and technological utilisation in the manufacture of low calorie gels (Alarc o-Silva et al., 1992), this investigation was carried out to test the suitability of that pectin to the confection of grape juice reduced calorie jellies in comparison with two types of commercial pectin. Aiming at the optimisation of low-calorie jelly formula, based on consumers preferences, the jellies were submitted to a sensory panel test judgement and instrumental texture-analysis.

LVSS conditions were sample injection time 25 s (2 psi) sample stacking time 2.9 min (—5 kV), after which the current reached 95 per cent of its maximum value. Samples were heated with a polyamide column SPE and then separated by LVSS-CE. Reprinted with permission from H.-Y. Huang el cd. [189].

Because damascenone is a ketone its volatility is reduced in products containing sulfur dioxide and thus its contribution to the odor of labrusca wines will be minimized f17). However, its contribution to the odor of grape juice and jelly may be substantial, especially since 5ng/g is 700 times the odor threshold reported for this compound in water (18)- In contrast, the methyl anthranilate concentration usually found in Concord grapes is only 50 times its threshold in water(19).
