PURPOSE: With the improvements of the microalgal cultivation industry, it became possible to add algal biomass and its metabolites in foods in order to create a balanced and health-food. METHODS: By determining the growth and the biochemical composition (lipids, carbohydrates and proteins), two algal strains were evaluated as a potential source of food additives – the newly isolated strain of the green algae Scenedesmus sp. and the red algae Porphyridium cruentum). RESULTS: It turned out that in Scenedesmus sp. BGP the most abundant component were the proteins (up tp 45 %), which makes this alga an excellent unconventional protein producer. As opposed to it, the biochemical composition of Porphyridium cruentum was dominated by carbohydrates (up to 57%), but there was also a high content of some essential polyunsaturated fatty acids: arachidonic (AA, 20:4; 13-29%) and eicosapentaenoic acid (EPA, 20:5, 24-25%). CONCLUSIONS: Microalgae are a really remarkable source of biomass and a wide range of substances, but this area is poorly explored. Both of the microalgal strains proved to be important sources of functional ingredients that could be successfully used as food additives together or separately.

Abstract All human senses participate in the sensory evaluation of food, which means that such features as taste, flavour, appearance, or texture determine the acceptance and choice of a dish. Seeking to satisfy consumer requirements and offer a dish or food with the desired organoleptic features, the food industry initially used a wide range of food additives compensating for the loss of colour, taste or flavour of the dish. At present, with an increase in consumers’ awareness and nutrition knowledge, departure is observed from the use of food additives to the benefit of using modern technologies in the food industry. The progress in food science, concerning especially, the phenomena taking place during the storage or processing of food, gives direction to the application of modern technical solutions or materials, and also provides guidelines within the area of gastronomic technology concerning the shaping of not only organoleptic features of the dish, but also activities aiming at the preservation of pro-health potential of food. This issue becomes even more important in the context of increasing epidemics of chronic non-communicable diseases (NCD) in contemporary western societies, in the etiopathogenesis of which, health behaviours play a crucial role. The subject of the report will be analysis of the current state of knowledge in the area of food and nutrition sciences, concerning the possibility of using modern gastronomic technologies in order to preserve or enhance the pro-health potential of food, possible to use within the primary and secondary prevention of NCD.

With the advent of green pharmaceuticals, the secondary metabolites derived from plants have provided numerous leads for the development of a wide range of therapeutic drugs; however the discovery of new drugs with novel structures has declined in the past few years. Cryptogams including lichens, bryophytes, and pteridophytes represent a group of small terrestrial plants that remain relatively untouched in the drug discovery process though some have been used as ethnomedicines by various tribes worldwide. Studies of their secondary metabolites are recent but reveal unique secondary metabolites which are not synthesized by higher plants. These compounds can have the potential to develop more potential herbal drugs for prevention and treatment of diseases The present article . deals with the secondary metabolites and pharmacological activities of cryptogams with an objective to bring them forth as potential source of biodynamic compounds of therapeutic value.

Since ancient times plant as sources of medicinal compounds have continued to play a dominant role in the maintenance of human health. To treat chronic and infectious diseases plants used in traditional medicine contain a wide range of ingredients. In this regard, Cassia auriculata L. (Caesalpiniaceae) is widely used in Ayurvedic medicine as a tonic, astringent and as a remedy for diabetes, conjunctivitis, ulcers, leprosy, skin and liver diseases. The aim of present study was to evaluate the antimicrobial activity of ethanolic extract of Cassia auriculata leaves and flowers (CALE & CAFE). CALE and CAFE exhibited broad spectrum antimicrobial activity against standard strains of Staphylococcus aureus, Escherichia coli and Bacillus subtilis and exhibited no antifungal activity against standard strains of Candida albicans and Aspergillus niger. Minimum inhibitory concentration (MIC) and Minimum bactericidal concentration (MBC) was carried out for CALE and CAFE. The results obtained in the present study indicate that the CALE and CAFE can be a potential source of natural antimicrobial agents.

AbstractThis study attempts to identify the significant role played by the secondary structure of collagen-derived peptides that are involved in lipid peroxide quenching in food products. Collagen was extracted from the skin of Perch and swim bladder of Rohu at 45-78% efficiency. It was identified as type-I based on a high molecular weight (110kDa) and its ion-exchange elution profile. The collagen samples were enzymatically hydrolyzed and collagen hydrolysate (CH) was extracted with an efficiency of 0.67-0.74g/g of collagen. The CH samples displayed a molecular weight in the range of 8.2-9.7kDa and exhibited a higher abundance of charges resulting in higher solubility. The structural studies revealed that the CH peptides existed in polyproline-II helix and formed a mimic-triple helix in a wide range of pH. In neutral and alkaline pH, the mimic helices joined to form a hierarchical quasi-fibrillar network that was smaller than collagen fibrils but also more dynamic. The CH exhibited >95% degradation in 15h through simulated digestion. The CH were able to decrease peroxide formation by 84.5-98.9% in commercially available cod liver and almond oil and increased the shelf life of soya bean oil by a factor of 5 after 6 months of storage. The addition of CH to cultured cells quenched peroxide ions generated in situ and decreased stressor activity by a factor of 12. The reason behind the high efficacy of CH was deciphered to be the proximal charge stabilization by the quasi-fibrillar network, which allowed efficient peroxide quenching and long-term stability.

Meat-processing enterprises produce a wide range of canned meat in different price categories. Complete information about the composition enables consumers to choose a product that meets their needs. However, the information on the label does not always correspond to the true composition of the canned food, and consumers are deceived in their expectations. Often, food additives that are not permitted by regulatory documents or are not declared on the label are introduced into the recipe. The purpose of this study was to identify the composition of canned meat lumps of popular brands produced from premium beef in accordance with GOST 32125 “Canned meat. Stewed meat”. The study was carried out by histological method. In many canned food samples, vegetable protein products, as well as thickening food additives, such as carrageenan, gums, starch, were found. The conclusions are made about the high level of falsification of this type of product.

Context: Jatropha belongs the spurge family Euphorbiaceae. Special interest mounting for its biodiesel which has created enthusiasm in cultivation of the species for oil extraction. Objectives: The study was conducted to develop the protocol for tissue and callus culture in Bangladeshi Jatropha curcus plant particularly to identify the most suitable explants for its wide scale micropropagation. Materials and Methods: Immature embryos taken from four developmental stages of fruits were cultured on growth regulator free MS liquid medium. After fifteen days of germination, elongated hypocotyls and two cotyledonary leaves were used as explants. Results: Embryo derived seedlings acted as the potential source of explants both for callus and plantlets. The immature embryo of size 0.87cm produced highest callus formation (83.33%) on MS medium supplemented with lower concentration of 2, 4-D (0.5 mg/l) and coconut water 2% (v/v). Immature embryos grown on MS basal medium supplemented with 2,4-D (0.2 mg/l, 0.5 mg/l and 1.0 mg/l) alone or in combination with coconut water 2% (v/v) exhibited a wide range of callus induction percentage (26-100%) for hypocotyls and (20 - 40%) for cotyledonary leaves. Conclusion: The age of immature embryo and addition of growth adjuvants and growth additive to the culture medium played the role in promoting better callus and plantlet formation.
