Eating Sturgeon: An Endangered Delicacy

Abstract

Since ancient times, sturgeon species have been valued for their rich nutritional qualities, which are crucial for human health today. They are linked with gastronomic delicacy and offer economic benefits, especially for the caviar industry. Today aquaculture produces more farmed and hybrid species due to rapidly declining wild sturgeon populations. Sturgeon diversification through processing can yield fingerlings, stocking material, meat or caviar. Because of its variety, sturgeon flesh includes highly digestible proteins, lipids, vitamins and minerals. Consuming sturgeon provides essential fatty acids that play important oxidative and anti-inflammatory roles in human cells. The purpose of this study is to examine the sustainability and economic value of eating sturgeon worldwide, the technology applied in food processing, and the challenges that food quality and authenticity, nutritional content and health effects pose. The issue of counterfeiting high-quality sturgeon products by dishonest means has to be adequately addressed. Digital tools to guarantee authenticity and transparency in the sturgeon value chain should be considered in the future.

Understanding the important variables to optimize glycolysis of polyethylene terephthalate with lanthanide-containing ionic liquids

“…Additionally, the oen 1 : 1 ratio of ionic liquid to metal salt to isolate these transition metal MILs leads to a high consumption of metal salts, which is not ideal with many of these metals being endangered elements. 31 The lanthanide series represents a unique class of metals to probe the desired trends for PET glycolysis. The ionic radius and Lewis acidity subtly change across the series, 32 allowing for an understanding of how Lewis acidity and metal ion size impacts PET depolymerization.…”

“…The ionic radius and Lewis acidity subtly change across the series, 32 allowing for an understanding of how Lewis acidity and metal ion size impacts PET depolymerization. Additionally, lanthanide metals can allow a wide range of coordination environments, 31 in which the ratio of IL to metal ion can be varied. While there are a few reports of lanthanide metal-containing MILs for luminescence and nuclear waste separation, [33][34][35] none have been used for catalytic depolymerization of polymers.…”

Identification and Verification of Novel Umami Peptides Isolated from Hybrid Sturgeon Meat (Acipenser baerii × Acipenser schrenckii)

“…15 Raposo et al studies indicated that sturgeon meat as a byproduct of caviar was not effectively utilized. 16 Our previous studies have focused on the exploration of the flavor of steamed sturgeon meat, and these results showed that umami and saltiness were the characteristic flavors of steamed sturgeon meat. However, these studies had focused on volatile flavor-active compounds, and changes in oral processing behavior of sturgeon meat, 17,18 with limited research conducted on nonvolatile flavor substances.…”

“…In the past decade, China’s sturgeon production has increased dramatically . Raposo et al studies indicated that sturgeon meat as a byproduct of caviar was not effectively utilized . Our previous studies have focused on the exploration of the flavor of steamed sturgeon meat, and these results showed that umami and saltiness were the characteristic flavors of steamed sturgeon meat.…”

Innovation in Green Materials for the Non-Contact Stabilization of Sensitive Works of Art: Preliminary Assessment and the First Application of Ultra-Low Viscosity Hydroxypropyl Methylcellulose (HPMC) by Ultrasonic Misting to Consolidate Unstable Porous and Powdery Media

“…Water interacts with delicate and often water-sensitive substrates, which increases treatment risks, while multiple misting applications (especially when treating large-scale objects) increase treatment time and costs. Moreover, Funori and Isinglass are products from the seaweed and sturgeon farming industries, that have begun to increasingly raise environmental and sustainability concerns [6]. High-density sturgeon farming operations often require significant amounts of water and are energy-intensive.…”
