A low fat fresh pork sausage based on chitosan was developed with the objective of obtaining a new functional meat product with improved properties and health claims promoting cholesterol reduction. Sausages were formulated with chitosan (2%, w/w) and different fat levels (5%, 12.5% and 20%, w/w). The results indicated that incorporation of 2% chitosan into produced pork sausages with health claims of reduction of cholesterol is technologically feasible. In addition, the chitosan reduced the microbial growth, revealing interesting fat and water absorption capacities, reduced lipid oxidation, provided greater stability in terms of colorimetric parameters and promoted positive firmer texture and gumminess. The reduction of fat content to levels of 5% was positively achieved with the incorporation of chitosan. Sensorial analysis showed that panelists did not detect any significant difference in taste and any unfavorable effect on the sausage appearance as a consequence of chitosan addition and variation of fat.
Goat meat is extensively known for its interesting nutritional value and for being an important source of protein with high quality. Its food derivatives are, therefore, a good alternative to develop new products addressed to health conscious consumers. In this work, a healthier goat product, namely, a low fat fresh sausage, was produced with the objective of evaluating the effect of inclusion of chitosan on quality, stability and shelf life. Sausages containing 2% chitosan were formulated with different fat levels (5%, 12.5% and 20%, w/w) and stored at 4 °C for 15 days. Results indicated the incorporation of 2% (w/w) chitosan was technologically feasible, due to the reduction of microbial growth and lipid oxidation, as well as the enhancement of red color. Additionally, the treated samples improved all the characteristics associated with cooking, showing the ability to bind water and fat and acquiring a firmer texture compared with control samples. Additionally, the reduction of fat content is technologically feasible without negative influences on the final product.
Purpose
Improper levels or excess of iodine may present a greater risk to health, for this reason, this paper aims to assess the iodine content present in salt and estimate the iodine concentration in school meals in a Brazilian northeast region.
Design/methodology/approach
Six samples of different salt brands sold in the city of Lagarto, Sergipe, Brazil were gathered for analyzing iodate concentration. The amounts of salt added to meals of four schools in the city and the weight of the provided meals were recorded during two consecutive days of gathering, thus obtaining data to estimate the iodine content of these meals. The rest of the meals and the nutritional composition of school meals were analyzed. A questionnaire for participants on the perception of salt was applied. For data analysis, α = 5% was used.
Findings
The iodine concentration in all salt samples followed legislation (15 to 45 mg of iodine/kg of salt), with the average of iodine ranged between 26.5 ± 1.29 and 33.9 ± 2.49 mg/kg (p < 0.001). The estimated iodine content in consumed school meals was 0.025 mg (25 µg), in meals of schools A and C, it was 0.03 ± 0.02 mg, and to schools B and D, it was 0.02 ± 0.01 mg (p < 0.001). Percentages of rest of the meals greater than 10% were found and the assessed food preparation showed low caloric and nutritional values.
Originality/value
The iodine content is in accordance with the salt iodization policy in Brazil, and that the average iodine estimate in school meals was considered adequate for this population.
