Histological Characteristics

Spirulina is one of the most highly-demanded and popular dietary supplements in the world. It is widely used in healthy nutrition both as a colorant and as a nutrient additive containing a large number of useful trace elements and vitamins. Spirulina is also used to create photosensitizers for photodynamic therapy, which is used to treat cancer and other diseases. Our objective was to conduct experiments and evaluate the eff ect of Spirulina solutions on the histological characteristics of Danio rerio organs. We tested the eff ect of Spirulina on adult fi sh Danio rerio in an acute 96-hour experiment at concentrations of: 0,1; 1,0, 10,0; 30,0; 100,0 mg/l. Afterwards, the histological micro-preparations obtained from the liver, intestines, kidneys, ovaries, and gills of the striped Danio were examined. The studies of the preparations have shown that the maximum allowable concentration of Spirulina solution for fi sh is 3 mg/l. These data can be used in hydrobiology for water disinfection methods, in ichthyopathology for fi sh treatment, and in food industry toxicology. Therefore, when using it for disinfection of water in the reservoir, aquatic invertebrates and fi sh will not be aff ected and sharp changes in the biocenosis of the reservoir are not expected.

Known as active oxygen Ozone (O3), are among the most effective antimicrobials. The sun's ultraviolet rays and ozone caused by electric arcs of lightning occurring instantly around the world, and is available as a protective shield protects the animals against the effects of the sun's radiation. In the food industry, directly or indirectly in contact with food during processing of foods and chemical treatment of water disinfection bacteriological emerges as an alternative protection method. In this study, the effects of the ozone applications will evaluated as an alternative to conventional disinfectants in food industry.

The situation with the virus Covide-19 worldwide, in addition to the many questions of how to best protect ourselves, drew the attention of people and professional community, to the significance and the importance that a healthy nutrition has in preserving and building up immunity, and thus also in the prevention and protect the organism from various negative agents. Due to increased consumer concern for their own health and the environment the organic food market is one of the fastest growing markets in the food industry. The main goal of the current research is to examine determinant factors influencing organic foods purchase in our region. The sample consisted of 571 subjects from Serbia and the region. The data were processed by the SPSS program, and the obtained results show that in our country, as well as anywhere in the world, the price is the most common barrier in the situation of buying organic food. Gender of our subjects was not a significant factor in making the decision and realization of the purchase, while their marital status and age had an influence in making the mentioned decision. In general, our research showed that younger respondents, who are not married, are the most common buyers of organic food.

Due to the superior ability of photocatalysis to inactivate a wide range of harmful microorganisms, it is being examined as a viable alternative to traditional disinfection methods such as chlorination, which can produce harmful byproducts. Photocatalysis is a versatile and effective process that can be adapted for use in many applications for disinfection in both air and water matrices. Additionally, photocatalytic surfaces are being developed and tested for use in the context of “self-disinfecting” materials. Studies on the photocatalytic technique for disinfection demonstrate this process to have potential for widespread applications in indoor air and environmental health, biological, and medical applications, laboratory and hospital applications, pharmaceutical and food industry, plant protection applications, wastewater and effluents treatment, and drinking water disinfection. Studies on photocatalytic disinfection using a variety of techniques and test organisms are reviewed, with an emphasis on the end-use application of developed technologies and methods.

Technological developments have left people tend to get used to working with the aid of automatic devices. The research that led to the automation has also been developed such as the detection of acid-base degree. The detector uses an Arduino Uno microcontroller components as the brains to run the program, and the pH sensor (Power of Hydrogen) as input that detect the state of a solution. In this solution and research tool used can be planned a new system. The system uses a microcontroller as a liaison between chemistry with the world of electrical technology. Produce percentage is almost close to perfect, as evidenced by the accuracy of the output of which is detected by a detector. In this study, the authors designed a detector-based acid-base arduino uno. The aim is to produce an acid-base detector with high accuracy than litmus paper sold in the market. With the alkaline acid detection devices are expected to ease the food industry, restaurants, and households in the detection of acid-base automatically. With an accuracy of ± 0.5 pH (25˚C).

Trade Control

Fish and invertebrates are subject to a wide range of disease agents. Many of their diseases are probably local in origin although a lengthy list of infections were probably imported via the vast array of exotic species which have been transferred to virtually all areas of the world. Since ail living organisms carry a full suite of microorganisms and larger parasites the likelihood of there being pathogens for local species among them is good. Introductions can occur in at least one of three separate ways: (1) intentional introductions for specific purposes, (2) accidental transport of biological agents via massive transfers of ballast waters or (3) through the ornamental or aquatic pet trade. Control measures and information services devised by the International Council for the Exploration of the Sea, the European Inland Fisheries Advisory Commission and the Office International des Epizooties are described.

Dr Wray's comments are, of course, very appropriate and encouraging. Aflatoxin was first detected in food commodities from other parts of the world. As concentrations in other parts of the world have usually been higher, little attention has been paid to the possibility of aflatoxin exposure in humans in the United States except by those who are directly involved in monitoring the human food supply (US Department of Agriculture, the food industry, and the US Food and Drug Administration).

Abstract: Saffron is one of the most expensive spices in the world, and its popularity as a tasty food additive is spreading rapidly through many cultures and cuisines. Minerals and heavy metals are minor components found in saffron, which play a key role in the identification of the geographical origin, quality control, and food traceability, while they also affect human health. The chemical elements in saffron are measured using various analytical methods, such as techniques based on spectrometry or spectroscopy, including atomic emission spectrometry, atomic absorption spectrometry, inductively coupled plasma optical emission spectrometry, and inductively coupled plasma mass spectrometry. The present study aimed to review the published articles about heavy metals and minerals in saffron across the world. To date, 64 chemical elements have been found in different types of saffron, which could be divided into three groups of macro-elements, trace elements, and heavy metals (trace elements with a lower gravity/greater than five times that of water and other inorganic sources). Furthermore, the chemical elements in the saffron samples of different countries have a wide range of concentrations. These differences may be affected by geographical condition such as physicochemical properties of the soil, weather and other environmental conditions like saffron cultivation and its genotype.

Trace elements other than iron only recently have gained importance in infant nutrition. Zinc and copper are two of the most essential trace elements. Zinc is a constituent of more than 100 metalloenzymes and plays an important role in growth, reproduction, tissue repair, and cellular immunity. Copper is a component of several metalloenzymes and is required for oxidative metabolism. Nutritional deficiencies of zinc now are recognized as being fairly prevalent throughout the world. Symptomatic zinc deficiency among infants can be attributed to several factors. It can be secondary to low zinc concentration in breast milk, low stores (as in prematurity), malabsorption (as in acrodermatitis enteropathica), or absence or inadequate amount in parenteral nutrition.
