Abstract

Purpose

The purpose of this paper is to detect total aflatoxin (AFT) in domestic and imported tea in Amol (north of Iran).

Design/methodology/approach

A total of 42 tea samples including 21 domestic and 21 imported tea samples of three popular commercial brands were purchased from retail stores and analyzed for estimation of AFT by ELISA technique. Data were analyzed by ANOVA using SPSS software.

Findings

All of the tea samples were contaminated with detectable amount of AFT ranging from 1.5‐16.5 ng/g. The average±SD concentration of AFT in domestic and imported samples was 7.1±2.96 and 6.11±3.94 ng/g, respectively, which is lower than national and EU standards (10 ng/g). The AFT content in 9.5 and 14.3 percent of domestic and imported samples was more than the limited concentration, respectively. There was no significant difference in AFT content of samples of different commercial brands (p>0.05).

Originality/value

No research had been done to detect and compare the AFT content of domestic and imported tea in Iran.

Abstract

A survey of the market diseases and aflatoxin contamination of tomato fruits was conducted in Sokoto in northwestern Nigeria in 2001 and 2002, respectively. Rotten tomato fruits sold at five different markets in Sokoto town, located at Central market, Kasuwar daji, Mabera, Minanata and Arkilla were heavily contaminated with moulds. Eight different fungi were found associated with the rotten tomato fruits sold in the five different markets. The associated fungi were Aspergillus niger, Aspergillus ochraceous, Aspergillus flavus, Aspergillus fumigatus, Penicillium citrinum and Helminthosporim fulvum, Curvularia lunata and Sclerotium rolfsii. A. flavus and A. niger have the highest rate of occurrence among the isolated fungi, while S. rolfsii was the least encountered. Pathogenicity tests revealed that of all the isolated fungi, A. ochraceous, A. flavus, Sclerotium rolfsii and P. citrinum were highly pathogenic with the first three leading to rapid disintegration of treated fruits in 3‐5 days. A. niger was moderately pathogenic, while H. fulvum was least pathogenic on tomato fruits. Aflatoxins were detected from the sampled diseased‐marketed tomato fruits and also from the marketed rotten tomato fruits after autoclaving for 15 minutes at 121°C.

This paper aims to provide information on the different methods of aflatoxin (AFT) degradation in rice.

Abstract

Purpose

This paper aims to provide information on the different methods of aflatoxin (AFT) degradation in rice.

Design/methodology/approach

Crops that are affected by AFT contamination include cereals, oilseeds, spices and tree nuts. AFT in rice may harm health to great extent, and if not properly determined, may cause death. The production and occurrence of mycotoxins differ depending on the geographic and climatic and environmental conditions; however, these toxicants can never be removed completely from the food supply.

Findings

Mycotoxins are commonly present in cereal grains such as rice and are not completely destroyed during their cooking and processing.

Originality/value

No review on detoxification of AFT has been found in rice.

Abstract

Mycotoxins have been a frequent topic of newspaper reports over the past year exciting such headlines as ‘liver cancer toxin fear in figs’, ‘health store's peanuts could give you cancer’ and ‘peanut cancer test developed by firm’. So, what are these mycotoxins and how much should they be feared?

The purpose of this paper is to evaluate safety of the enzymatic treatment (garlic peroxidase) for removing aflatoxin B1 (AFB1) from foods.

Abstract

Purpose

The purpose of this paper is to evaluate safety of the enzymatic treatment (garlic peroxidase) for removing aflatoxin B1 (AFB1) from foods.

Design/methodology/approach

An in vivo study was carried out on male wistar rats for three weeks. Since AFB1 is a hepatotoxic; the effect of AFB1 and the enzymatic detoxification of AFB1 on the liver function was studied by determining the serum activities of various hepatic enzymes in different groups of experimental rats.

Findings

The peroxidase (POD) isolated from garlic possess AFB1 degrading properties and the overall detoxification is safe to be used in various foods/feeds as the reaction products produced no toxicity in the adult male wistar rats. Rats fed with aflatoxin contaminated diet possessed increased activities of all the hepatic enzymes investigated; showing symptoms of liver damage compared to rats fed with enzyme treated diet.

Practical implications

The results of this study can be utilized for commercialization of the garlic POD mediated AFB1 detoxification from feeds/foods.

Originality/value

The aflatoxin detoxyfying abilities of garlic POD and its in vivo safety studies have not been reported so far.

Abstract

Samples of dry‐roasted groundnuts purchased from street hawkers, markets and retail shops in southwestern Nigeria were analysed for moisture content, fungal populations and aflatoxin contamination. The moisture content varied from 2.1 to 3.6 per cent, while the mould counts using the dilution plating method ranged from 2.9 × 102 to 6.3 × 102 colony‐forming units per gram in samples. Aflatoxin B1 was found in 64.2 per cent of samples with a mean of 25.5 ppb. Aflatoxins B2, G1 and G2 were detected in 26.4, 11.3 and 2.8 per cent of the samples with mean levels of 10.7, 7.2 and 8 ppb respectively in contaminated samples. It is concluded that the regular consumption of DRG by Nigerians might present potential health hazards.

Abstract

Purpose

The purpose of this paper is to analyze the current situation of multidimensional food safety assurance in Serbia, as an official candidate for European Union (EU) membership, in relation to its EU food law harmonization efforts.

Design/methodology/approach

Serbian assurance scheme was covered in this paper included food safety legislation, control and standards.

Findings

The food safety system in Serbia needs improvements in the area of effectiveness and efficiency of food safety control and inspection services, knowledge and expertise of state inspectors, governmental officials, food safety consultants and auditors. Additionally, problems related to the overlapping responsibilities of various legal authorities and inspection services have to be solved, with an improved transparency and communication between legal authorities, customers, consumers and food business operators.

Originality/value

An overview of current situation in food safety assurance in Serbia is shown.

Abstract

Purpose

This paper is a systemic review on enset plant’s role in Ethiopian people’s life as the source of food. This paper aims to summarize the traditional processing and preparation methods of enset-based foods and their nutritional composition.

Design/methodology/approach

Available scientific articles were collected and reviewed for enset plant evaluation, description, enset plant’s role in Ethiopian people’s food security, post harvesting and traditional processing of enset plants, microbiology of the fermented enset foods, different foods reported from enset, nutritional profile of the three food from enset base (kocho, bulla and amicho) and other non-food applications of enset plant.

Findings

Enset plant has a predominant role in people living in the southern part of Ethiopia. This plant is drought-tolerant and provides many non-food applications. Harvesting of the enset plant, preparing for fermentation and food preparations follow the traditional route by using the indigenous knowledge and practices. Limited studies have been reported on the microbiology of the enset fermentation, but various types of microbes have been reported. In case of nutritional composition, foods from enset are reported to contain high carbohydrate and minerals content, such as calcium, potassium and zinc, but limited protein content; they are also the best source of the essential amino acids such as lysine and leucine. Limited data are available on vitamins, anti-oxidant and fatty acids profiles of enset-based foods. The existing data indicate variations, and the reasons for variability are discussed in this paper.

Originality/value

Scientific reviews on enset food nutrition profile and related issues are scarce; this paper will compile information about enset plant-based foods for researchers for their future research.

Abstract

The pig industry plays a major role in the economy of Denmark. A large proportion of the production is exported to markets in the United Kingdom, Germany, France, USA and Japan. Considerable resources are devoted to maintaining high standards of food safety. Describes and explains the legislation, procedures and surveillance which have been devised to ensure that the presence of chemical residues is kept to a minimum.
