Understanding Membrane Fouling during the Clarification of Pomegranate Juice after Egg Albumin Pretreatment: An Analysis Using Hermia’s Empirical Models | Chapter 6 | Food Science and Agriculture: Research Highlights Vol. 1

Pomegranate (Punica granatum L., Punicaceae) is a popular tropical non-citrus fruit known for its attractive aroma, refreshing flavor, and favorable Brix/acid ratio. This juice is commonly used in fruit-based beverages, either alone or mixed with other fruit juices. The introduction of membrane processing enables the production of additive-free juices with high quality and a natural fresh-like taste. There have been a few studies on membrane filtration in fruit juice processing. Therefore, the present study investigated membrane fouling during the clarification of pomegranate juice after pretreatment with egg albumin. Pomegranates of the (cv. Ganesh) variety, sourced from the local market in Bapatla, Guntur District, Andhra Pradesh, were chosen for their high juice yield preferred by many juice processors and vendors.

Hermia’s empirical models were applied to evaluate the fouling phenomena in microfiltration (MF) and ultrafiltration (UF) of pomegranate juice. The flux data was fitted into existing fouling models to elucidate the fouling mechanisms during membrane processing. For each mechanism, a mathematical model has been developed to predict a decline in permeate flux and its limiting value due to fouling. The coefficient of determination (R²) values for the gel layer model ranged from 0.804 to 0.977 for the 0.2 µm pore size membrane when filtering pomegranate juice. These R² values suggest intermediate pore blocking followed by gel layer formation. It was observed that a gel layer formed upon prolonged duration of MF with pomegranate juice. Poor-fitting was observed for the SPB (Sieving Porosity Model) and CPB (Cake Porosity Model) models.

Anti-HIV and Anticandidal Properties of Punica granatum L. (Pomegranate): A Pharmacological Agent for the Oral Cavity | Chapter 7 | New Advances in Medicine and Medical Science Vol. 1

 Pomegranate (Punica granatum) forests have long been used widely in traditional cure to treat a wide range of illnesses, containing dental and oral diseases. The most frequent dispassionate manifestation in HIV patients is generated by Candida albicans, which has happened demonstrated to have strong anticandidal belongings in recent years. Since the spoken cavity is critical from diagnosis to adherence to HAART remedy in HIV/AIDS population, the present review offers a inexact overview of current knowledge of the chemical arrangement and anti-HIV and anticandidal properties of the plant variety P. granatum involved in the oral crater in order to hook up in the development of novel anti-HIV powers that will be useful from now on clinical practice. The biography reviewed revealed that vulgar extracts of pomegranate and its main compounds private, and in particular, anthocyanins and gallotannins retain inhibitory activity on different HIV-goals, including binding viral proteins and the 3 replicative HIV-enzymes. Pomegranate too demonstrated anticandidal effects on 10 various species in the biography that was reviewed. Consequently, pomegranate appears to be a great aspirant to investigate and include into the treatment of the oral crater in HIV/AIDS patients, in that apart from its two-fold-pharmacological effects such as antiviral and anticandidal, blue and red colors mixed together represents an easily approachable inexpensive and safe instinctive source, accompanying a wide range of oral drug forms.

Evaluation of Bioagents against Ceratocystis fimbriata Causing Wilt of Pomegranate | Chapter 2 | Recent Progress in Microbiology and Biotechnology Vol. 2

 

One of the important fruit crops, pomegranate (Punica granatum L.) is now highly endangered by the wilting caused by Ceratocystis fimbriata. Against Ceratocystis fimbriata, eleven bioagents were evaluated in vitro. Trichoderma harzianum, Trichoderma isolate 1 and Trichoderma isolate 5 reported the highest percent inhibition of mycelial growth (100 percent) among the bioagents tested. It was found to be considerably superior to the remainder of the b ioagents tested. This was followed by Trichoderma isolate 4, Trichoderma virens, Pseudomonas fluorescens and Trichoderma isolate 2. In comparison, Pseudomonas putida (43.12 percent), Paecilomyces lilacinus (44.98 percent), Trichoderma isolate 3 (48.94 percent) and Bacillus subtilis (55.00 percent) recorded minimum parasitic activity.

Linear Discriminant Analysis a Useful Tool for Characterization of Pomegranate Growers | Chapter 11 | Current Strategies in Economics and Management Vol.6

 

An attempt has been made to focus and identify the discrete characteristics of the two contrast groups
determining pomegranate yield. It examines the difference between the two groups of Pomegranate
growers on the basis of some socio-economic characteristics, input application factors, managerial
factors and labour characteristics. Linear Discriminant Analysis (LDA) has been used to discriminate
the Pomegranate cultivators belonging to two groups (high yielding and low yielding groups) based on
multiple characters simultaneously with an objective that which factors are prospective with respect to
yield attributing characters. Out of 48 different factors it is found that 22 factors have significant role in
Pomegranate production. Observed significant correlation between adoption index and realization
index in case of high and low yielding groups it also indicates that high yielding farmers who belongs
to lower size group are good adopters of technology. Pomegranate is a capital intensive orchard crop,
the level of adoption depends not only on quantum of inputs but also on the appropriate know-how
practices at the farm level. This study would be helpful to the pomegranate growers for making
decisions related to pomegranate production.
