AI Article Synopsis
- The study analyzed strawberry and raspberry seeds to assess their dietary effects on rats, focusing on components like dietary fiber and polyphenols.
- Strawberry seeds contained monomeric ellagitannins and a dimer while raspberry seeds had a dimer and a trimer, leading to different physiological responses in rats.
- Rats fed raspberry seeds showed better fermentation efficiency and improved atherogenic index, marking an advantage over strawberry seeds in terms of reducing serum triacylglycerol levels.
Article Abstract
Strawberry and raspberry seeds were chemically analyzed and added as dietary ingredients to investigate the physiological response of rats. In both cases the main component was dietary fiber and the main polyphenols were ellagitannins (ET). The strawberry ET were mainly constituted by monomers and a dimer, agrimoniin, whereas raspberry ET were mainly constituted by a dimer, sanguiin-H-6, and a trimer, lambertianin-C. The lower content and the less polymerized structure of strawberry ET resulted in a higher cecal metabolites concentration (mainly nasutin and urolithin-A) in comparison to rats fed diet containing raspberry seeds. Dietary raspberry seeds, a source of dietary fiber, despite being richer in polyphenol compounds, were better utilized in fermentation processes, resulting in enhanced production of short-chain fatty acids. As opposed to strawberry seeds, the treatment with raspberry seeds beneficially improved the atherogenic index of a diet, mainly due to reduced triacylglycerol concentration in the serum.

In this study, biodegradable and active films based on sodium alginate incorporated with different concentrations of oils (25% and 50%) from fruit seeds were developed for potential applications in food packaging. The ultraviolet and visible (UV-VIS) spectra of raspberry seed oil (RSO) and black currant seed oil (BCSO) indicated differences in bioactive compounds, such as tocopherols, phenolic compounds, carotenoids, chlorophyll, and oxidative status (amounts of dienes, trienes, and tetraenes) of active components added to alginate films. The study encompassed the color, structure, and thermal stability analysis of sodium alginate films incorporated with RSO and BCSO and their mixtures.

The purpose of this study was to characterize unconventional cold-pressed seed oils (rosehip, strawberry, blackcurrant, carrot, plum, pomegranate, radish, and raspberry) as novel alternative edible oil source. A chemical characterization of different lipid components (total fatty acid composition, triacylglycerols, and vitamin E) and volatiles responsible for the particular aroma of these oils was reported. All the oils showed a content of unsaturated fatty acids, mainly oleic, linoleic, and α-linolenic acid, that potentially contribute to the prevention of cardiovascular diseases, in the range of 80%-90%.

Real-time seed detection on resource-constrained embedded devices is essential for the agriculture industry and crop yield. However, traditional seed variety detection methods either suffer from low accuracy or cannot directly run on embedded devices with desirable real-time performance. In this paper, we focus on the detection of rapeseed varieties and design a dual-dimensional (spatial and channel) pruning method to lighten the YOLOv7 (a popular object detection model based on deep learning).

Over the last 10 years, global raspberry production has increased by 47.89%, based mainly on the red raspberry species (Rubus idaeus). However, the black raspberry (Rubus occidentalis), although less consumed, is resistant to one of the most important diseases for the crop, the late leaf rust caused by Acculeastrum americanum fungus.
