“…Microorganisms can produce biopolymers through fermentative processes of different bioresources (e.g., polyhydroxyalkanoates), and biomass may be produced directly from different types of plants (starch, cellulose, pectin, zein, gluten) and animal materials (chitosan, gelatin, caseins) ( 46 ). Biopolymer production does not include phthalates as glyceryl monoesters, glycerol, fatty acids, and polyethylene glycol are used as common plasticizers ( 47 ).…”

Translocation of Phthalates From Food Packaging Materials Into Minced Beef

There has been increased concern regarding the potential human health risks associated with exposure to phthalates. Research indicates that food intake is the most critical exposure pathway for phthalates. This study aimed to investigate packaged beef samples for the presence of dimethyl terephthalate (DMTP), di-n-butyl phthalate (DnBP), and diisooctyl phthalate (DiOP) and to assess their translocation from the common form of food packaging procured from various Saint-Petersburg and Leningrad region shops. The packaging samples include paper and different types of plastic. Phthalates were extracted by dichloromethane and analyzed by gas chromatography coupled with mass spectrometry (GC-MS). While DnBP had the highest mean values in beef from 34.5 to 378.5 μg·kg−1, DiOP displayed the lowest mean values from LOD to 37 μg·kg−1. The larger contact area and the presence of distributed fat on the surface of the minced meat resulted in significantly higher phthalate translocation than beef slices. Further, DMTP was not detected in any samples. However, the examined food packages do not meet the requirements of Russian, EU and USA legislation, as DnBP migrates to meat. Calculated maximum DnBP daily intake of 0.167 μg·kg−1·day−1 for chilled minced beef in vacuum packaging did not exceed tolerable daily intake (TDI) level. The most alarming results are concerning the phthalates presence in beef farmed in the Leningrad region and not subjected to any plastic packaging. A full-scale study is warranted to determine the pathways and sources of phthalates migration in the food chain.

“…The natural polymers called carbohydrates are polysaccharides, which are naturally degradable macromolecules (biodegradable) [1,2]. One of the most important natural polysaccharides is starch [3], granules composed of two polymers of glucoses: amylose and amylopectin found in food grains [4,5].…”

Se analizó almidones de cinco diferentes orígenes botánicos: papa (Solanum tuberosum), quinua (Chenopodium quinoa), yuca (Manihot esculenta), trigo (Triticum aestivum) y arroz (Oryza sativa) como muestra estándar. Se obtuvo valores de humedad, características de gelatinización, porcentaje de amilosa y amilopectina, morfología del gránulo de almidón y retrogradación, para determinar la relación entre las mismas con la capacidad absorbente de cada almidón. Los resultados mostraron que el almidón de quinua retrogradado es el de máxima capacidad absorbente. Este almidón presenta un gránulo de almidón más pequeño, una relación más alta de amilosa y amilopectina (mayor porcentaje de amilopectina) y un bajo grado de gelatinización. La retrogradación favorece la absorción debido a la ruptura de los gránulos permitiendo que las moléculas de agua sean más fácilmente retenidas en la estructura. Aun así, los demás tipos de almidón también llegan a tener capacidad absorbente inmediata.
