Oil content, fatty acid composition and the distribution of vitamin-E-active compounds of selected Turkish seeds that are typically by-products of the food processing industries (linseed, apricot, pear, fennel, peanut, apple, cotton, quince and chufa), were determined. The oil content of the samples ranged from 16.9 to 53.4 g/100 g. The dominating fatty acids were oleic acid (apricot seed oil, peanut oil, and chufa seed oil) in the range of 52.5 to 68.4 g/100 g and linoleic acid (pear seed oil, apple seed oil, cottonseed oil and quince seed oil) with 48.1 to 56.3 g/100 g, while in linseed oil mainly α-linolenic acid (53.2 g/100 g) and in fennel seed oil mainly 18:1 fatty acids (80.5 g/100 g) with petroselinic acid predominating. The total content of vitamin-E-active compounds ranged from 20.1 (fennel seed oil) to 96 mg/100 g (apple seed oil). The predominant isomers were established as α- and γ-tocopherol.

“…Conventional crops and agricultural practices will continue to provide the bulk of the edible oils market in the foreseeable future, but may ultimately be unable to meet the projected increase in demands (3,6). More intensive research is required to allow for increased oil productivity by plants (173). Areas of possible activity have been presented in Table I.…”

Biotechnology and the fats and oils industry — An overview

Biotechnology is the application of single or multicellular organisms and of associated or derived enzyme systems to the production of desirable products. Particular discussion has been made of the derivation of fats and oils from animals, plants and microorganisms. General consideration has been given to methods, primarily plant breeding and agronomic practices for the improvement of the quantity and quality of oil produced by soybean, rapeseed, palm and sunflower. The possible importance of yeasts, fungi and algae as sources of single cell oil has been examined. A particular role of these systems in the production of specialty oils has been suggested. Enzyme systems, either associated with the intact cell or in isolation, can be used to varying degrees of success in either a free or immobilized form. Particular reference has been made to application of these systems to reactions including specific hydrolysis of triacyb glycerols, acylation of glycerol, interesterification of triacylglycerols, wax ester formation and steroid transformations. Consideration has been given to particular plants and microorganisms as sources of new fats and oils. The major impact of biotechnology on the industry is believed to be associated with the production of high value specialty products including cocoa butter substitutes, biosurfactants, waxes and various prostaglandin derivatives. General consideration has been given to the possible relative importance of plant and microbial systems, engineering and scale-up problems, and overall economics of present biotechnological procedures.

Plant regeneration from in vitro cultures of cotyledon explants and anthers of Sinapis alba and its implications on breeding of crucifers

1989

Protocols for plant regeneration from cotyledon explant and anther cultures of Sinapis alba have been developed for creating doubled-haploids and somaclonal variation . Among the several cultivars tested in this study, only 'Arda' responded well to in vitro plant regeneration both from anther-as well as cotyledoncultures . Multiple shoot formation in cotyledon explants, which always followed a brief callusing phase, was found to be the best on MS medium with ZEA (1 .0 mg/l) and NAA (0.1 mg/1) . Regeneration frequency declined sharply in the absence of auxin or presence of other cytokinins and/or auxin . The frequency of shoot regeneration also declined with reduction in the photoperiod to 16h . On MS + BAP (1 .0 mg/1) + NAA (1 .0 mg/1) medium, cotyledonary explants showed profuse callusing, which could regenerate shoots on high ZEA + low NAA/IAA medium . However, it declined with progressing time in culture . Anthers, excised from fresh as well as cold pretreated buds, cultured on 10% sucrose containing MS media with different hormonal constitution, developed calli and/or embryos . Initial culture temperature was important with embryogenesis occurring only in anthers cultured at 30° C for 3 weeks . A high temperature (35° C) treatment was lethal for both callus as well as embryo formation . While BAP + NAA 'and ZEA + NAA/IAA supported embryogenesis, further plant regeneration from anther-or embryo-callus could be achieved in ZEA + NAA/IAA media . Some of the regenerants flowered already in vitro and had small and sterile flowers . Cytological examination of some of the root differentiating calli indicated the presence of haploid as well as diploid cells . Shoots were rooted during prolonged incubation on the same medium or on transfer to MS (reduced)/ B5 + ZEA + NAA media .
