转基因食品标识对于转基因食品安全管理有着重要的价值和意义。当前欧盟和美国在转基因食品标识管理方面呈现出强制和自愿两种进路,二者在标识类型、方法、形式和内容等方面差异明显。欧美作出不同的制度选择,是由双方在转基因食品安全管理理念与价值取向、贸易状况、文化传统以及民众观念等多方面的不同决定的。中国可从欧美制度比较中汲取经验,在立足于中国国情的基础上对转基因食品标识管理作出相应完善。 相似文献

Quality of the cookies substituted with germinated mung bean flour (GMF) to rice flour (RF) to produce gluten-free cookies were investigated in this study. The GMF was used to formulate with the RF to obtain the composite flours with different total protein contents of 6, 9, 12, 15, 18 and 21 (%, d.b). The increase in the substituted amounts of GMF contributed to the lower baking loss, diameter and spread ratio, but the higher thickness and hardness of the cookies as compared to the RF-based cookie. The cookies with more GMF substitution expressed lower lightness (L*) values, but higher redness (a*) and yellowness (b*) values than the others. The cookies substituted with 60% of the GMF (60-GMFC) exhibited similar baking loss, thickness, diameter, spread ratio and lightness values to the wheat flour (WF)-based cookies. The total amounts of essential amino acids and the sum of histidine, lysine and methionine of the composite flour-based cookies were 3.90% and 1.64%, significantly higher than those of the RF-based cookie (1.93% and 0.66%, respectively) or the WF-based cookie (1.70% and 0.58%, respectively). As a result, healthy gluten-free cookies could be prepared using the RF with the substitution of the germinated mung bean flour. 相似文献

BACKGROUND: A glass‐matrix fertiliser (GMF), a by‐product from ceramic industries, releases nutrients only in the presence of complexing solutions, similar to those exuded by plant roots. This ensures a slow release of nutrients over time, limiting the risk of their loss in the environment. With the aim to improve fertiliser performance, GMF was mixed with vine vinasse (DVV), pastazzo (a by‐product of the citrus processing industry, PAS) or green compost (COMP) and nutrient release was evaluated by citric and chloridric acid extraction, at different concentrations. RESULTS: Theoretical and actual nutrients release were compared to evaluate possible synergistic effects due to the organic component added to the mineral fertiliser: phosphorus (+7.1%), K (+4.8%), Fe (+8.5%) and Zn (+5.5%) were released more efficiently by 2% citric acid from GMF + DVV, while Ca availability was increased (+5.3%) by 2% citric acid from GMF + PAS mixture. Both DVV and COMP increased by 12–18% the Fe release from GFM matrix. CONCLUSION: Organic biomasses added to GMF increased the release of some macro and micronutrients through an ‘activation effect’, which suggests the employment of these organo‐mineral fertilisers also in short‐cycle crops production. Moreover, the re‐use of some agro‐industrial organic residues gives another ‘adding value’ to this novel organo‐mineral fertilfertilisers. Copyright © 2011 Society of Chemical Industry 相似文献

In Tanzania, germinated cereal flour is added to weaning foods consisting of ungerminated cereal or root crop flour and sometimes legumes to reduce bulk and viscosity, and increase nutrient density. However, there is no standard procedure for germinated cereal flour preparation and addition to gruels. This study was conducted to improve the chemical, physical and microbiological quality of millet and corn gruels based on protein and energy requirements for infants. Germinated millet flour (GMF) was more efficient than germinated corn flour in reducing gruel viscosity to < 3 Pascal s in 5 min. Washing before germination did not significantly reduce the microbial levels in GMF. Formulations consisting of millet, corn or combinations with soybean or peanut at a cereal: legume ratio of 7:3, and GMF were prepared by traditional and improved methods. In the lat- 相似文献
