Early in 2007, the main problem for administrative enforcement is the issue of food additives. This paper analyzes one such incident: the fermented flour paste incident in Beijing roast duck that occurred in early 2007. We put forward suggested ways to perfect the legal system regarding Chinese food additives by focusing on legal and management mechanisms. This includes optimizing higher-level laws for food additives, improving the standards system, cultivating the appropriate concepts, implementing preventive measures, and facilitating routine law enforcement.展开更多

To do that assessment, a two-step cross-sectional survey based on food ethnography methods was used. A total of 61 marketplaces were visited in seven towns and rural districts as part of the availability and affordability survey, while 400 children (aged 6 to 59 months) were surveyed to track the uses of infant flours at the household level. The results obtained reveal that pre-manufactured infant flour is sold more in urban areas (Cotonou, Porto-Novo and Parakou) than in rural ones. The average infant flours price did not vary (p = 0.985) in any given year (regardless of abundance or lean periods) nor does it vary (p = 0.133) from one point of sale to another (drugstore or supermarkets). However, the average price is found to be expensive considering the purchasing power of the households surveyed. On the other hand, the amount of ingredients used in the production of the flour types found on the market complies with the recommendations of the Codex Alimentarius, unlike the homemade ones. Pre-manufactured infant flour is found to be outside of the economic reach of most households (92%) who rely heavily on the homemade ones to feed their children. In light of the above, public authorities should help improve geographic access and pricing affordability to quality infant flour for low-income households in urban and remote areas. Moreover, awareness should be raised among mothers relative to the importance of complementary feeding through education on good nutrition practices.展开更多

The results showed that 94% of yield, 92% of water retention and 97% of fat retention were achieved with the addition of 5.92 g of whole chia flour and 15 g of water per 100 g of burger. The n-3 fatty content increased from 704.57 ± 21.66 mg to 1551.71 ± 47.71 mg/100g of cooked burger when the chia flour was added, enhancing nutritional quality indices of lipid. A good oxidative stability, with minimum formation of conjugated dienes, hydroperoxides and thiobarbituric acid reactive substances during 30 days frozen storage was obtained too, probably due to the presence of polyphenolic compounds with antiradical activity and reducing power in the fibrous fraction of the flour chia. The results from the present study highlight remarkable technological applications of whole chia flour as food ingredient in the design of healthier fish meat commodities.展开更多

After the substitution, the highest protein content was observed in PDBM (1.78 ± 0.12)% followed by PSBM, (1.35 ± 0.01)% and the lowest was in the control (0.91 ± 0.55)%. Moreover, cookies fortified with date palm powder increased the carbohydrate and fat contents compared to the control and significantly increased the calorific value of PDBM. The formulated cookies were significantly higher (p < 0.05) in iron (39.95 ± 3.00) mg/100 g and zinc (13.65 ± 1.61) mg/100 g in PDBM compared to other cookies. The date palm powder incorporated in cookies significantly increases the darkening of biscuits during cooking. The organoleptic characteristics of PDBM and PSBM were rated overall best when specific parameters were tested. With the shortage of wheat and importation constraints, an alternative provides a great market opportunity for local products like potatoes and beans. In addition, fortifying food products as cookies eaten by all will contribute to a more food and nutrition-secured world.展开更多
