Abstract

Algae are exclusively aquatic photosynthetic organisms that are microscopic or macroscopic, unicellular or multicellular and distributed across the globe. They are a potential source of food, feed, medicine and natural pigments. A variety of natural pigments are available from algae including chlorophyll a, b, c d, phycobiliproteins, carotenes and xanthophylls. The xanthophylls include acyloxyfucoxanthin, alloxanthin, astaxanthin, crocoxanthin, diadinoxanthin, diatoxanthin, fucoxanthin, loroxanthin, monadoxanthin, neoxanthin, nostoxanthin, perdinin, Prasinoxanthin, siphonaxanthin, vaucheriaxanthin, violaxanthin, lutein, zeaxanthin, β-cryptoxanthin, while carotenes include echinenone, α-carotene, β-carotene, γ-carotene, lycopene, phytoene, phytofluene. These pigments have applications as pharmaceuticals and nutraceuticals and in the food industry for beverages and animal feed production. The conventional methods for the extraction of pigments are solid-liquid extraction, liquid-liquid extraction and soxhlet extraction. All these methods are less efficient, time-consuming and have higher solvent consumption. For a standardized extraction of natural pigments from algal biomass advanced procedures are in practice which includes Supercritical fluid extraction, Pressurized liquid extraction, Microwave-assisted extraction, Pulsed electric field, Moderate electric field, Ultrahigh pressure extraction, Ultrasound-assisted extraction, Subcritical dimethyl ether extraction, Enzyme assisted extraction and Natural deep eutectic solvents. In the present review, these methods for pigment extraction from algae are discussed in detail. [ABSTRACT FROM AUTHOR]

Abstract

Advancement in technology is continued as the time is passed. The biological active ingredients technology is the challenging issues for both the researchers and manufacturers. In last decade, much research has been happened about the potential health benefits of pro and prebiotic ingredients. Probiotics are the live microorganisms when given in adequate amount confer health benefits but the prebiotics are indigestible ingredients that enhance the activity of one or more probiotics in the colon. The therapeutic potential of these two biological active ingredients is the outcome of emerging field of biotechnology. A number of studies indicating therapeutic potential of probiotics regarding gastrointestinal health, cancer, constipation, immunomodulation, Helicobacter pylori, liver disease and urogenital infection have been documented. Similarly, prebiotics also improved helpful for many communicable and non-communicable diseases. It can be seen that advancement in the biotechnology field offer great choice to deliver a marvelous health advantages. Although the market for probiotic and prebiotic food and supplements has been increased in this new era but still need to develop food and supplements containing these two active ingredients with the cooperation of legal bodies of the country.

26. Functional role of bioactive peptides with special reference to cheeses.

*PROTEIN precursors, *FOOD industry, *DIETARY bioactive peptides
Abstract

Growing perception about diet in relation to health has extended the necessity to explore the biologically active components present in native foods. In this review, bioactive peptides released from cheeses that may have important physiological functions are discussed. Bioactive encrypted peptides can be generated from precursor milk proteins during food processing via enzymatic hydrolysis and fermentation. Generally, biofunctionalities of peptides are latent within precursor proteins. Bioactive peptides liberated from cheeses exhibit numerous potential therapeutic roles: for example, angiotensinogen‐converting enzyme (ACE) inhibition, antioxidant, anti‐thrombotic, anti‐microbial, anti‐cancer and anti‐inflammatory. This article critically focuses on the functional roles of bioactive peptides derived from different cheeses. [ABSTRACT FROM AUTHOR]

Abstract

The present study was planned to evaluate anti‐proliferative activity of water‐soluble peptides (WSPs) extracts of Cheddar cheeses made with buffalo and cow milk using a colon adenocarcinoma cell line. Cheese extracts were prepared at different stages of ripening up to six months. Anti‐proliferative activity of extracts was evaluated through cell viability assay, cell cycle arrest and apoptosis induction using colon cancer (HCT‐116) cell line. A dose‐dependent increase in activity was observed till five months of ripening. Cells population was relatively higher at G0/G1 phase of cell cycle. Moreover, apoptosis induction was also observed in a dose‐dependent manner. [ABSTRACT FROM AUTHOR]

Abstract

This article aimed to assess the anti‐inflammatory and anticancer potential of water‐soluble peptide (WSP) extracts from buffalo and cow milk Cheddar cheeses. Anti‐inflammatory activity was evaluated on the basis of nitric oxide (NO) production in lipopolysaccharide‐stimulated macrophage (RAW‐264.7) cells. A cell viability assay, cell cycle arrest and apoptosis were performed to explore anticancer activity in a colon cancer model (HT‐29). The WSP extracts of both Cheddar cheeses effectively inhibited NO production in activated macrophages. Maximum growth inhibition was observed in the HT‐29 cells at concentrations of 400 and 500 μg/mL. A significant increase in cell population at G0/G1 phase of the cell cycle was observed. Moreover, the WSP extracts also induced extensive apoptosis in colon cancer cells. [ABSTRACT FROM AUTHOR]
