The passion fruit or grenadilla is usually consumed in the form of juice and its pleasant intensive aroma and flavor make it an attractive element for the food industry. The objective of the present work is to determine the effects of membrane technologies such as tangential microfiltration and reverse osmosis on the physicochemical characteristics of passion fruit extracts. The characteristics of the various extracts were determined according to conventional methods. In addition, statistical methods were applied to the data collected in order to determine the effects of membrane technologies. The results showed a yield of 89.33% for the extraction of the microfiltered juice and a volume reduction factor of 16.75 for the concentrate. In addition, the microfiltration-concentration process significantly (p <0.05) influenced the physicochemical parameters of the extracts produced. Thus, tangential microfiltration made it possible to clarify the crude extract by changing from a turbidity of 89.23 ± 1.71 to 0.72 ± 0.02 NTU. It has also resulted in a significant decrease in pH and flavonoids contents. Principal component analysis confirmed the existence of differences between the extracts produced despite the various correlations between their characteristics. It revealed that the JB and CMFT extracts are characterized by their high pH and low density. On the other hand, the COI extract is characterized by its brix degree, viscosity, conductivity and high vitamin C content. In addition, reverse osmosis has the advantage of concentrating the compounds of interest of clarified juice with a concentration factor ranging from 2.15 to 9.39.

This paper reports the physicochemical characteristics of the seed oils from different varieties of passion fruit (Passiflora alata Curtis, Passiflora edulis f. flavicarpa and Passiflora quadrangularis) cultivated in Brazil, Roraima. The oil  from passion fruit, within the range of 19.29±0.02; 21.34±0.22 e 14.24±0.16%, respectively. The physicohemical characteristics of the extracted oils were: free fatty acid contents (0.84±0.01 - 2.73±0.05 % mg KOH g-1 as oleic acid), iodine value (101.63±0.18 - 125.96±0.13 g of I2 100 g-1 of oil), and saponification index (90.56±0.32 - 179.06±0.19 mg KOH g-1 of oil). The oils revealed a reasonable oxidative parameter range as depicted by the determinations of index peroxide value (1.92±0.09 – 3.05±0.03 meqO2 kg-1 of oil). Linoleic acid was the major fatty acid found in all the seed oils with contributions of 55.75-63.42% of the total fatty acids (FA). Other fatty acids detected were known to be oleic acid (19.3-20.1%), palmitic acid (10.8-12.8%) and stearic acid (3.25-4.25%). Through the DPPH test we observed the presence of antioxidants in the three oil samples. The results of the present study indicate that the seeds of the tested passion fruit varieties from Roraima are a potential source of high-linoleic oil and thus can be explored for commercial use and value addition.

The food we eat plays a key aspect in determining our overall health and immunity. Improving our immunity during the Covid-19 pandemic is challenging for all age groups. So this study focused on formulating a ready to drink called probiotic fruit yogurt from less utilized passion fruits (Passiflora edulis), as a good option to build resilience in the body against infections and also to help the planters of Thandikudi hills, Tamil Nadu to promote their harvest into a valuable product. Passion fruits were procured and handled in a very hygienic manner. The formulation of stirred fruit yogurts was carried out in three different ratios (10%, 15%, and 20% pulp). These samples were standardized by sensory evaluation (9 points hedonic scale) and physicochemical parameters (pH). Fruit yogurt made from 20% passion fruit pulp scored the highest value in the mean score (8.5±0.17) for sensory evaluation except for texture. The pH value of the passion fruit yogurt was 3.5 found and it was more acidic compared to the plain yogurt value of 3.7 because of the addition of fruit pulp which was balanced by the addition of sugar/stevia. The acceptability of the stirred probiotic fruit yogurt with 20% pulp was mainly because of the flavoring compounds of the yellow passion fruit (P. edulis Sims f. flavicarpa Deg).

This study aims to determine the minimum inhibitory concentration (MIC) and bactericidal concentration (MBC) of the fermentation filtrate (FF) on red passion fruit pulp (Passiflora edulis Sims.) against Escherichia coli Extended Spectrum Beta Lactamase (ESBL) and Methicillin Resistant Staphylococcus aureus (MRSA). The method used was the fermentation of red passion fruit pulp for 24 h using De Man Rogosa Sharpe Broth (MRS-broth) media, and the result showed that the FF of red passion fruit pulp made a dilution series concentration of 50 percent, 25 percent, 12.5 percent, 6.25 percent. Considering this result, the MIC FF of red passion fruit cells against ESBL and MRSA has a 25 percent dilution concentration, while MBC has a 50 percent dilution concentration. This shows that red passion fruit has the potential to be developed as antibacterial material, especially to fight bacteria that are already resistant.

Fruit based beverages are one of the foremost categories of beverages that are consumed globally. Since fruit beverages are easily digestible, health conscious, highly refreshing, thirst quenching, appetizing and nutritionally far superior to most of the synthetic beverages available in the market, consumption of fruit based beverages have been increased dramatically. Natural extracts of tropical fruits such as Carica papaya (papaya), Passiflora edulis (passion fruit), and natural flavor extract of Camellia sinensis (leaves) and Cinnamomum verum (Cinnamon barks) were extracted and used as the main ingredients of this product while sugar, Citric acid, pectin were used as the supplementary ingredients. The best fruit pulp ratio and the best natural flavoring agent out of tea and cinnamon was determined through structured sensory evaluations by participating 30 semi trained panelists. Further experiments were also performed   to find the optimum amount of pectin to reduce hard packing and to determine the shelf life of the developed beverage and to develop the natural pectin extraction method by using unutilized parts of the Passiflora edulis fruit. Proximate analysis studies and microbiological studies were also carried out. Collected data were statistically analyzed using Kruskal-Wallis non parametric analysis and sample 293 which is containing 15% total fruit pulp with papaya to passion fruit ratio 2:1 and cinnamon as the flavoring agents was the best product formulae. According to the proximate analysis data, fat, protein, carbohydrates, fiber and the ash content were 0.41%, 0.11%, 13.13%, 0.052%, 3.028% and 83.27% respectively. The total plate count was 12 cfu/ml and yeast and molds were 0 cfu/ml of the product and Physico-chemical studies reveals that, the product can be preserved for 30 days under 4±1 0C condition. The average pectin percentage of Passiflora edulis and Carica papaya were 6.9 % and 4.5 % respectively.
