Noodles are a leading food in the world, and color is a key determinant of consumer acceptance. In this review the two prominent forms of wheat noodles are considered, white salted and alkaline. Many of the preparation and evaluation strategies are the same for both, with prominence placed on 'brightness' (L*) or a lack of discoloration (ΔL*), and the absence of 'specks'. All raw noodles darken over time. Increasing protein content of flours almost always translates into darker noodles. Greater discoloration is also associated with higher flour extraction rates, higher ash contents and higher starch damage...

BACKGROUND: Trace element fingerprinting has been widely used for identification of provenance of regional food. In the case of the products from conventional agriculture, it is expected that the elemental composition will comply that of the commercially available substrate at the plants. Therefore, for products without direct relationship with the regional soil the region-specific differences in elemental composition are no longer recognisable. The idea of this work is labeling of tomatoes with rare earth elements (REE) in the ultra-trace range for food authentication...

BACKGROUND: Ochratoxin A (OTA) is a mycotoxin produced by several species of Aspergillus and Penicillium fungi. The presence of OTA in raisins is mainly related to the black Aspergillus spp. contamination. This toxin poses risks to human and animal health due to their high toxicity and carcinogenicity. Therefore, new strategies to avoid the risk associated to OTA are necessary. RESULTS: In the present study, a comparison between the effects of the antifungal protein PgAFP and potassium sorbate (E-202), on the growth of Aspergillus carbonarius, biosynthetic- and stress-related gene expression and its OTA production at two water activity (aw ) levels 0...

In this work, the effect of sodium citrate mixed with tobacco, in presence and absence of SBA-15 material, was studied by TGA/FTIR under N2 and air atmospheres. Depending on the atmosphere used, the decomposition of sodium citrate changes considerably at high temperatures, mainly due to the oxidation of the residue. The analysis of the experimental and calculated DTG data of the sodium citrate/SBA-15 mixtures allows the observation of marked widening of the peaks appearing at lower temperatures, due to the presence of SBA-15, while the expected peak at high temperatures in air completely disappears...
