The pine nuts, as the most expensive ones, are a source of healthy oil. Accordingly, the hypothesis was genetic differences of pine species (Pinus spp.) affect their nut oil content and fatty acid phytovariability. A completely randomized design experiment with three replicates was done in Isfahan Flower Garden, Iran, using four pine species of chir pine (Pinus longifolia<...

Background and Objectives: Roselle (Hibiscus sabdariffa L.) is one of the valuable plants grown in tropical and subtropical regions such as some parts of Iran. Roselle calyces are commonly used to make&nbsp; herbal tea as well as a natural food color additive. However, Roselle seeds are usually discarded as by&ndash;products, while they can be used as a source of nutritious and functional compo...

The aim of this study was to determine the chemical composition physico-chemical properties, fatty acid and tocopherol compositions and total phenolic compounds and evaluate the radical-scavenging activity of crude oil extracted from passion fruit (Passiflora edulis f. flavicarpa) seeds, aiming to use the agro-industrial by-products. The oil seed extraction was performed by Soxhlet method and t...

The main objective of the current work was to evaluate the suitability of ultrasound-assisted extraction (UAE) for the recovery of oil from papaya seed as compared to conventional extraction techniques (i.e., Soxhlet extraction (SXE) and solvent extraction (SE)). In the present study, the recovery yield, fatty acid composition and triacylglycerol profile of papaya seed oil obtained from differe...

Salicylic acid (SA) is an endogenous plant growth regulator, acting as non enzymatic antioxidant and has a regulatory effect on some physiological and biochemical processes. Therefore, this work was conducted during two successive summer seasons to evaluate the performance of two sunflower cultivars (Sakha 53 and Giza 102) to salicylic acid. The plants were grown at the experimental station of ...

Seeds are another product in addition to leaves (raw materials for teas) of tea (Camellia sinensis L.) plant. The great increase of tea consumption in recent years raises the challenge of finding commercial applications for tea seeds. In the present study, supercritical carbon dioxide (SC-CO(2)) extraction edible oil from tea seed was carried out, response surface methodology (RSM) was used to ...

The aim of the present experiment was to investigate how different types of dietary fats and levels of vitamin E affect the fatty acid profile of egg yolk during refrigerated storage of table eggs. ISA Brown hens (n=90; 28 weeks old) were randomly assigned to five experimental diets. The dietary treatments included: (1) control diet without fat supplementation and added vitamin E (2) 5% Alifet ...

Hemp (Cannabis sativa L.) is an annual plant that has been bred for centuries and its main products are hemp seeds and fibers. Fibers from the stalk are still used in production of durable fabrics and specialty papers, such as paper money, tea bags, canvas, linen, cigarette paper, and other strong, thin papers used to make thick books, like the Holy Bible1. Hemp production was prohibited due to...
