AI Article Synopsis
- Meadowfoam (Limnanthes alba) seed meal contains glucosinolate, which can be altered through fermentation.
- The study found that fermenting the seed meal led to the complete breakdown of glucolimnanthin and produced beneficial compounds with herbicidal properties.
- These findings suggest that refining glucosinolate-rich seed meals could create effective bioherbicides for agricultural use.
Article Abstract
Meadowfoam ( Limnanthes alba ) is an oilseed crop grown in western Oregon. After extraction of the oil from the seeds, the remaining seed meal contains 2-4% of the glucosinolate glucolimnanthin. This study investigated the effect of fermentation of seed meal on its chemical composition and the effect of the altered composition on downy brome ( Bromus tectorum ) coleoptile emergence. Incubation of enzyme-inactive seed meal with enzyme-active seeds (1% by weight) resulted in complete degradation of glucolimnanthin and formation of 3-methoxybenzyl isothiocyanate in 28% yield. Fermentation in the presence of an aqueous solution of FeSO(4) (10 mM) resulted in the formation of 3-methoxyphenylacetonitrile and 2-(3-methoxyphenyl)ethanethioamide, a novel natural product. The formation of the isothiocyanate, the nitrile, and the thioamide, as a total, correlated with an increase of herbicidal potency of the seed meal (r(2) = 0.96). The results of this study open new possibilities for the refinement of glucosinolate-containing seed meals for use as bioherbicides.

This comprehensive study focused on evaluating and selecting seven distinct commercial membranes to develop BTESE/PA membranes. This method effectively facilitated the extraction of cynaroside from the complex composition of peony seed meal. We subsequently conducted a thorough investigation into its biological properties.

Feed cost represents about 70% of the total production costs of rabbit farms. There is little research on the usage of Berseem and Fenugreek seeds as substitutes for soybeans in rabbit diets. The current investigation was conducted to assess the influence of dietary inclusion of Fenugreek and/or Berseem seeds at varying levels as a substitute for soybean meal on reproductive performance, milk production, maternal behaviour, economic efficiency, mammary gland and ovarian histology, and relative expression of reproductive genes of New Zealand White rabbit does.

The development of cardiometabolic (CM) diseases is associated with chronic low-grade inflammation, partly linked to alterations of the gut microbiota (GM) and reduced intestinal integrity. The SINFONI project investigates a multifunctional (MF) nutritional strategy's impact combining different bioactive compounds on inflammation, GM modulation and CM profile. In this randomized crossover-controlled study, 30 subjects at CM-risk consumed MF cereal-products, enriched with polyphenols, fibers, slowly-digestible starch, omega-3 fatty acids or Control cereal-products (without bioactive compounds) for 2 months.

Background: An unhealthy diet is a key risk factor for non-communicable diseases (NCD), which account for a significant number of premature deaths and disability-adjusted life years worldwide. Office workers are reported to have unhealthy and unbalanced diets, while being sedentary due to the nature of their work, placing them at a greater risk of NCD. This study aimed to determine dietary intake and associated factors among sedentary office workers in Southern Sri Lanka.

Depending on the soybean processing plant, gums and soapstocks may be added back to soybean meal during soybean processing. Despite potential effects on soybean meal quality, there is limited information available on the composition and variation in soybean by-products and the resulting soybean meal if by-products are added back during processing. A total of 36 soybean by-product samples from 14 plants across 8 different companies were examined in an industry survey evaluating the composition and variation of soybean gums and soapstocks across the US.
