Health-Promoting Opportunities of Hemp Hull: The Potential of Bioactive Compounds
J Diet Suppl. 2024 Feb 1:1-15. doi: 10.1080/19390211.2024.2308264. Online ahead of print.ABSTRACTHemp hull is the outer coat of the hemp seed, derived from the plant Cannabis sativa L., Cannabaceae. While much attention has been paid to hemp seed for its oil, protein and micronutrient content, far less attention has been given to hemp hull, a side stream of hemp processing. Hemp hull is a source of bioactive compounds, dietary fiber, minerals as well as protein, lipids and carbohydrates. Of note, two bioactive compounds, n-trans-caffeoyltyramine and n-trans-feruloyltyramine have been identified in hemp hull as key bioactiv...

Puzzling prehistoric artifacts served a practical purpose: ropemaking
In 2015, archaeologists working at a cave in southwestern Germany found an enigmatic perforated baton in a cave called Hohle Fels. It was a near-perfect match for an artifact found in 1983 in a cave down the road. Carved from single pieces of mammoth ivory, the Hohle Fels baton—roughly 20 centimeters long, about the length of a large paperback book—had
multiple holes with spiraling grooves around the openings
.
Similar objects have been found elsewhere in Germany and in nearby France, often made from ivory or antler. They date from the last ice age, more than 35,000 years ago, a time when human hunters ...

Ultrasonic-ethanol pretreatment assisted aqueous enzymatic extraction of hemp seed oil with low Δ < sup > 9 < /sup > -THC
In this study, ultrasonic-ethanol pretreatment combined with AEE was developed for oil extraction from hemp seeds. The oil yield reached a maximum of 23.32 % at 200 W ultrasonic power and 30 min ultrasonic time, at this point, the degradation rate of Δ9-THC was 83.11 %. By determining the composition of hemp seed before and after pretreatment, it was shown that ultrasonic-ethanol pretreatment reduced the protein content of the raw material. An enzyme mixture consisting of pectinase and hemicellulase (1/1/1, w/w/w) was experimentally determined to be used, and the AEE extraction conditions were optimized using the Plackett...

Factors Associated with Delta-8 THC Retail Availability in Fort Worth, Texas, 2021-2022
Conclusions: Both timepoints had similar proportions of Delta-8 THC retailers, indicating that despite the uncertain legal landscape in Texas, interest in Delta-8 did not appear to be declining. Geographic socioeconomic disparities were observed among locations with alcohol retail licenses. Future regulations may include minimum distances from specific locations (e.g., schools), particularly in more disadvantaged areas. Increasing the compliance of Texas Delta-8 THC retailers to have the required hemp license is important for surveillance and product safety.PMID:38247162 | DOI:10.1080/10826084.2024.2305793 (Source: Substance Use and Misuse)

Cannabidiol and brain function: current knowledge and future perspectives
Cannabidiol (CBD) is a naturally occurring non-psychoactive cannabinoid found in Cannabis sativa, commonly known as cannabis or hemp. Although currently available CBD products do not meet the safety standards of most food safety authorities to be approved as a dietary supplement or food additive, CBD has been gaining widespread attention in recent years due to its various potential health benefits. While primarily known for its therapeutic effects in managing epileptic seizures, psychosis, anxiety, (neuropathic) pain, and inflammation, CBD’s influence on brain function has also piqued the interest of researchers and indi...

The analysis of classical, polynomial regression and cubic spline mathematical models in hemp biodiesel optimization: an experimental comparison
In this study, methyl ester was produced from hemp oil by transesterification using sodium hydroxide (NaOH). Next, classical optimization study was carried out to determine the effects of catalyst amount, alcohol:oil molar ratio, reaction temperature, and reaction time variables on biodiesel yield. Secondly, the cubic spline mathematical model (CSMM) and polynomial regression mathematical model (PRMM) were applied to the first data of this optimization. Among these optimization methods, the utmost biodiesel yield registered was 96.115% at hemp seed oil (HSO):methanol molar ratio of 5.59:1, catalyst concentration of 0.531 w...

Identification, characterization, and molecular docking of immunomodulatory oligopeptides from bioavailable hempseed protein hydrolysates
Food Res Int. 2024 Jan;176:113712. doi: 10.1016/j.foodres.2023.113712. Epub 2023 Nov 29.ABSTRACTPromoting dietary patterns in which the content of vegetables is higher than the current consumption of them is one of the strategies to achieve a sustainable food system while promoting health in humans. Hemp (Cannabis sativa L.) protein contains bioactive peptides that can be released via enzymatic hydrolysis. These peptides must reach the target organ in order to potentially exert bioactivity and regulate specific metabolic pathways. The peptides contained in two bioavailable hempseed protein hydrolysates (bioHPHs) showing an...

Viruses, Vol. 16, Pages 30: New Insights into Hop Latent Viroid Detection, Infectivity, Host Range, and Transmission
This study was undertaken to expand our basic knowledge of HLVd infectivity, transmission, and host range. HLVd-specific primers were used for RT-PCR detection in plant samples and were able to detect HLVd in as little as 5 picograms of total RNA. A survey of hemp samples obtained from a diseased production system proved sole infection of HLVd (72%) with no coexistence of hop stunt viroid. HLVd was infectious through successive passage assays using a crude sap or total RNA extract derived from infected hemp. HLVd was also highly transmissible through hemp seeds at rates of 58 to 80%. Host range assays revealed new hosts fo...

Selectivity of herbicides used in corn on Crotalaria ochroleuca G. Don
The objective of this study was to evaluate the selectivity of pre and post-emergent herbicides on C. ochroleuca. Two field experiments were conducted in randomized blocks with four replications, involving the pre-emergence and post-emergence application of different herbicide treatments. For the pre-emergent ones, amicarbazone, atrazine and flumioxazin provided phytotoxicity higher than 90% and, consequently, low plant biomass. On the other hand, acetochlor and s-metolachlor did not cause phytotoxicity and did not affect the dry mass of crotalaria. In post-emergence, atrazine + mesotrione showed phytotoxicity >95%, fol...

Removal of cationic dyes from aqueous solution using polyacrylic acid modified hemp stem
Environ Sci Pollut Res Int. 2023 Dec 21. doi: 10.1007/s11356-023-31627-w. Online ahead of print.ABSTRACTWater pollution caused by dyes is a pressing environmental challenge due to their persistence and difficulty in degradation. Herein, an anionic adsorbent (HS-PAANa) was synthesized by grafting polyacrylic acid (PAA) onto the agricultural waste-hemp stem (HS). The obtained HS-PAANa adsorbent exhibited rapid adsorption kinetics, high adsorption capacity, and a favorable preference for cationic dyes, such as methylene blue (MB) and crystal violet (CV). The experimental data fit well with the pseudo-second-order kinetic mode...
