On allergy to cottonseed oil.
The question of specific sensitiveness to edible cottonseed oil in contradistinction to cottonseed is worthy of recognition and more critical study than it has received. Discussions of cottonseed sensitiveness in textbooks on allergy generally imply that cutaneous sensitiveness to allergenic extracts of cottonseed or cottonseed meal signifies clinical sensitiveness to foods containing salad oil or vegetable shortening made from cottonseed oil. A pronounced difference of opinion concerning this concept is displayed in the testimony of six allergists who appeared as expert witnesses at a public hearing 1 in relation to label declaration of vegetable oils in salad dressings. Opportunity to study allergy to cottonseed oil is rare. 1 Hence, worthy of record are results of a concurrent comparison of two cottonseed-sensitive allergic subjects, one of whom disclaimed and the other proclaimed a demonstrable sensitiveness to edible cottonseed oil.

Assessment of some agro-technological parameters of cactus pear fruit ( Opuntia ficus-indica Mill . ) in Morocco cultivars
Cactaceae had always attracted attention by their strange shapes and important adaptability supporting extreme conditions. For this reasons, Fruit traits were measured on 13 cultivars growing in different locations in Morocco. Results show significant differences between the cultivars. The source of this variation was probably genetic without excluding the geographic effects. The Tamri, Berkan, Ait Baha cultivars showed small fruit dimensions and weight. In contrast, Sidi-Ifni M, Nador, Mohammedia and Ben Guerir were greater than 100 g by fruit. Sidi-Ifni M, Hoceima, Mohammedia and Nador, although larger, contained few seeds, about 200 seeds per fruit; while Tamri, Ait Baha, Safi, Meknes and Tafraout contained over than 230 seeds per fruit. High levels of juice about 62 ml/100 g pulp were obtained with Sidi-Ifni M, Nador, Mohammedia and Ben Guerir cultivars. Total sugars of the 13 cultivars were quite similar and pH was low in Tamri and close to neutrality in the rest of cultivars. Therefore, oil extracted from Opuntia ficus-indica seeds constituted 13.6% of the whole seed. Thin-layer chromatography in conjunction with gas-liquid chromatography-mass spectrometry revealed a relatively high degree of unsaturation, 83.32% and 16% for saturated fatty acid, with a linoleic acid content of 63.66% followed by oleic 18.34%, palmitic 12.84% and stearic acid 2.81%. Based on these results, O. ficus-indica seed oil appears to be a good potential source of edible oil for human and (or) animal consumption. Our investigation describes that Tamri and Tafraout cultivars are not really a commercial viable fruit due to low total soluble solids value and highest seeds number per fruit. Against Mohammedia, Sidi Ifni M and Nador cultivars proved to have the highest fruit weight, very good total soluble solids value and low number of seeds, these cultivars can therefore be planted for both fruit production and for harvesting of cladodes for animal feed.
