Abstract— Yoghurt is a coagulated milk product that results from the fermentation of lactose in milk by Lactobacillus bulgaricus and Streptococcus thermphillus. The health benefits can be increased by adding native fruit pulps. Yoghurt with different fruit pulp includes papaya and cactus pear was prepared and stored up to 10 days. The fruit were added at the rate of 5%, 10% and 15%w/w. Physicochemical properties of yoghurt samples include moisture, protein, fat, carbohydrate and ash were determined at first days of storage. Acidity, pH, syneresis, water holding capacity (WHC), total count, coliform group, yeast &mould and organoleptic properties were evaluated yoghurts at zero time, after 5 and 10 days of storage at refrigerator.There were significantly differences between plain yoghurt and fruit yogurt in the pH, moisture, ash, protein, carbohydrate content and titratable acidity amounts 5 day of storage. The results showed that acidity increased over the storage period. Highest values for WHC and lowest values for syneresis were belonged to yogurt with 15 % cactus pear and 10 days storage with 71.21% and 16.01%, respectively. Sensory evaluation results showed that there were significant differences among the yoghurt samples. The yoghurt containing papaya pulp had the highest overall acceptability scores as compare to other fruit yogurt samples and also plain yogurt. The results of current study demonstrated that the addition of fruits to the yogurt significantly improved the quality of yogurt.

— The present study evaluated physico-chemical and sensorial qualities of value added banana products. Unripe fruits of Cavendish variety were processed for making banana flour. Value added products like dough, chapatti and banana kheer were prepared from banana flour. Rice and basin flour were also used in chappati. Unripe banana fruit, banana flour and their products were analysed for pH, titratable acidity, moisture (%), TSS (Brix) and vitamin C. The results showed that the maximum pH (7.68) and TSS (26.30 brix) recorded from the kheer, However, Ash (0.86%) and vitamin C (18.3mg/100gm) were observed highest in chapatti prepared from banana and rice flours as compared to chappati prepared from banana flour only (12.54). Unripe banana fruits had maximum percentage of moisture (72.08%) in comparison to banana products. The minimum pH (6.79) and titratable acidity (0.02) were observed from the unripe banana fruits. While, banana flour had minimum moisture (7.49%). Minimum TSS (5.30) were recorded in chappati prepared from mixture of banana-rice flour and banana-basin flour. The results shows that processing of banana for value added products alter the physico-chemical qualities of banana.

Hylocereus (sweet pitayas).
Pitaya (Hylocereusspp.) originated principally
from the tropical and subtropical forest regions
of Latin Americas, including North, Central and
South America (Crane and Balerdi 2005; Luders
and McMahon, 2006).
It is known as dragon fruit in Asia as its skin is
covered with bracts (scales) like dragon.
5. It is a small fruit climbing cactus that has
received world-wide recognition as an
ornamental plant for its large, scented, night-
blooming flowers.
It is a non-climacteric fruit covered with rosy-
red skin studded with green scales and its
white flesh contains many small black seeds
Other names; Strawberry pear, Night blooming

respectively.
They observed that the fat content and
total solid content of the set yoghurt
ranged from 2.8 to 3.74% and 22.19 to
26.15%, respectively.
The developed product had a pH value of
3.95 to 4.05 and a titratable acidity value
of 0.8% to 1.25% it is increased during
storage
34. The Titratable acidity of yoghurts increased
over the storage period. And pH is
decreased
35. Yeast and mold populations in the
developed dragon fruit yoghurts did not
exceed 103 CFU/g until the 15 day of
storage period.
E. coli was not detected in all the yoghurts
during storage, thus, showing hygienic
production procedure.
The shelf-life of the dragon fruit yoghurt
was 15 days under refrigerated conditions
(4 °C).
36. Conclusion
Dragon fruit can be effectively used for the
development of set fruit-yoghurts.
The highest sensory properties were
observed in the product which consisted of
10% dragon fruit juice, 10% sugar and 0.8%
gelatin.
Developed product had 23.58 % total solids,
9.64% solid-non-fat and 3.2% fat
Dragon fruit yoghurt can be stored for 15
days under refrigeration conditions (4°C)
without changing its quality parameters.
