Summary: In this study, the researchers investigated the degradation efficiency of cyanogenic glycosides in cassava using a cassava linamarase mutant. The results showed that the mutant had improved catalytic activity and thermal stability, leading to a higher degradation efficiency of cyanogenic glycosides. The study also highlighted the potential of the mutant in food applications. However, further research is needed to understand the catalytic mechanism.

Summary: The study found that ultrasonic pretreatment (UPT) is an effective way to remove cyanide from cassava in a short period of time, enhancing the safety of cassava. UPT can improve the processing of cassava by directly eliminating hydrogen cyanide and indirectly degrading cyanogenic glycosides, while also promoting enzymatic hydrolysis.

Summary: This paper evaluated the dietary risks of cassava cyanide and proposed a maximum residue limit for cyanogenic glycosides in cassava. The results showed no chronic health risk across all populations concerning cassava consumption. It is suggested that risk assessment of cyanide for foods rich in CNGs should be based on CNGs quantification rather than that of CN-.

Summary: This study investigated cassava food products in Melbourne, Australia and found that ready-to-eat cassava chips had the highest cyanide content, with imported products having higher levels than those manufactured in Australia. Cyanide was detected in frozen cassava products, but processing according to instructions significantly reduced the levels. The study emphasizes the need for ongoing testing of cassava food products.

Summary: Cassava is an important staple crop worldwide, but it has received the least investment compared to other major global crops. It is grown by subsistence farmers in countries with limited resources for crop improvement. The starchy roots of cassava are high in calories but low in protein and essential nutrients. They also contain potentially toxic levels of cyanogenic glycosides that must be reduced before consumption. Recent progress in understanding the metabolism of cyanogens in cassava may offer a solution to creating a safer and more nutritious crop.

Summary: Cassava, an important root crop in tropical countries, was formulated into biopesticide CCE to combat borer insect pests. Cell studies showed dose-dependent cytotoxicity of CCE on A549 cells, with different effects on free radical scavenging and nitrite radicals, and a negative correlation with mitochondrial and lysosomal functions. Higher concentrations of CCE led to necrotic cell death rather than apoptosis, indicating significant anti-proliferative ability.

Summary: Most of the fresh cassava roots and cassava products purchased in Singapore during 2016-2017 exceeded the Codex Alimentarius limit for 'sweet' (boil-and-eat) cassava, but the cyanogenic potential in all cassava flour and ready-to-eat chips was below 20 mg kg(-1).

Summary: Solid-state fermentation (SSF) is a promising technology for producing value-added products from cassava. It offers advantages such as lower costs, reduced water usage, and higher product yields. SSF can enhance the nutritional value of cassava-based products and minimize waste by utilizing cassava waste as a substrate. However, optimizing process conditions and developing cost-effective production processes are essential for successful commercialization.

Summary: The study tested the cytotoxic effect of cassava cyanide extract (CCE) on human glioblastoma cells (LN229). The results showed that CCE had a dose-dependent toxicity on glioblastoma cells, reducing cell viability by negatively affecting mitochondrial activity, lysosomal and cytoskeletal integrity. The CCE also interfered with the cell cycle and induced cell death, suggesting its potential as an antineoplastic agent against glioblastoma cells.

Summary: Cassava production generates significant by-products, such as leaves and tuber peel, which can be valorized instead of being considered as waste. However, the presence of cyanide and insoluble fibers presents challenges for their conversion into valuable products. This study investigated the changes in cyanide concentration and quality of cassava leaves after mechanical pressing and in tuber peel after enzyme treatment.

Summary: This study investigated the effectiveness of a pocket-sized SCiO molecular sensor to predict starch content in freshly ground cassava roots. The predictive ability of SCiO was compared to two commercially available near-infrared spectrometers. The study found that SCiO provided satisfactory prediction results and could be a cost-effective solution for phenotyping the starch content of fresh roots in resource-limited cassava breeding programs.

Summary: Konzo, a distinct upper motor neuron disease associated with cyanogenic diet and chronic malnutrition, predominantly affects children and women of childbearing age in sub-Saharan Africa. The gut microbiome structure is highly variable depending on region of sampling, and unique enrichments of bacterial species and functional pathways have been identified in prone regions of the Congo that potentially modulate the susceptibility of konzo. Using metagenomic profiling in 180 individuals from the Democratic Republic of the Congo, associations between the gut microbiome and konzo have been found.

Summary: Amygdalin is a natural cyanogenic glycoside found in the seeds of some edible plants, with both anticancer activity and toxicity due to hydrogen cyanide production. Despite studies on cancer cell lines, clinical evidence for its anticancer properties is not fully confirmed. High dose exposures to amygdalin can lead to cyanide toxicity.

Summary: The Fe-salen based probe showed promising results in detecting pyrophosphate through detailed UV-Vis and fluorescence mechanistic studies. The molecular subunits disassemble in the presence of pyrophosphate analyte, with the aqua form of the complex (1-OH2) identified as the active species. The flexibility in molecular recognition and binding of pyrophosphate by the probe explains its outstanding selectivity over other (poly)oxophosphates and potentially competing analytes.

Summary: This study investigates the variations in lipid digestion profiles among individuals of different ages using in vitro digestion models. The findings suggest that adults have a more comprehensive lipid digestion compared to infants, and infants tend to release shorter chain length and more saturated free fatty acids during digestion. Additionally, the particle sizes in the stomach of the elderly were consistently larger. This study enhances our understanding of how lipids with different degrees of unsaturation undergo digestion in diverse age groups.

Summary: Chitosan-pectin emulsion-filled hydrogel (EFH) was developed to enhance the bioaccessibility of lipophilic bioactive compounds through intestinal delivery. The EFH, prepared without crosslinking agents, demonstrated improved mechanical strength and compactness with higher pectin concentration. It retained the emulsion at pH 2.0 and released it at pH 7.4, resulting in enhanced release of free fatty acids and improved bioaccessibility of curcumin.

Summary: Horse's milk, with its high nutritional value and low allergenic proteins, could be a substitute for cow's milk in infant consumption. A proteomic method was used to identify and compare milk fat globule membrane (MFGM) and whey proteins from different horse breeds. The study found differences in protein composition and functionality, which could support the development of formulas more suitable for human infants.

Summary: This study investigated the acidification of aroma-enhanced black tea during storage. Analysis of non-volatile substances and organic acids using UPLC-Q-TOF/MS and HPLC revealed a decrease in soluble sugars and amino acids, while an increase in organic acids such as oxalic acid, malic acid, and quinic acid. In vitro experiments further demonstrated that the acidification is a result of the decomposition of sugars and amino acids by heating, as well as the oxidation of aromatic aldehydes. Additionally, the study showed that the taste composition of tea infusion is altered, with reduced amino acids, catechins, soluble sugars, and flavonoids. This research provides a theoretical basis for improving the quality of black tea.
