In a 2021, Chinese researchers examined the impact of E171 on lipid digestion and vitamin D3 bioaccessibility in a simulated human gastrointestinal tract model. They examined Vitamin D’s bioaccessibility, or the amount it was released in the gastrointestinal tract, becoming available for absorption, and found it “significantly decreased from 80% to 74%” with the addition of E171. In the experiment, E171 decreased lipid digestion dose-dependently. Researchers wrote: “The findings of this study enhance our understanding toward the potential impact of E171 on the nutritional attributes of foods for human digestion health.”  The study was published in the Journal of Agricultural and Food Chemistry

  • In addition to functionality, window profiles also contribute significantly to the architectural style of a buildingwhat is a window profile. Traditional homes often feature more ornate profiles, while modern designs tend towards sleek, minimalist frames.

  • The window profile, or window frame, can be made mainly from three different materials: plastic, i.e. PVC, wood and aluminium. Plastic profiles are the most common and the most economical. Laminated timber frames are valued for their naturalness and rigidity, which is particularly important for larger patio windows. However, they are more expensive, heavier and require regular maintenance. Aluminium profiles, on the other hand, although they have the highest cost, are the most rigid, durable and maintenance-free. This is why their share of the market is steadily increasing, although due primarily to their high price, they still do not exceed a few percent.

  • Furthermore, cast iron picket castings are relatively easy to install and maintain
