Seeds and Fruits

One of the xanthophyll pigments present in various leaves, seeds and fruits, and in yolk of egg. It is often present in company with lutein, of which it is an isomer. It bears the same relation to -carotene as lutein does to a-caro tene. 

In the past, expression presses were used in many processes for extracting oil and juice, generally from seeds and fruits such as olives. Batch presses were typically used in these apphcations, and hand unloading of the pressed cake was often required. Batch presses that require hand unloading or extensive cleaning between pressings are rarely used now descriptions of various types are presented in earlier editions of this handbook. This section, therefore, describes mainly continuous presses. 

Screw presses were traditionally used for seeds and fruits that had to be mechanically ruptured to release the liquid in the seeds or cells... 

Starch is a widely distributed material which occurs in roots, seeds, and fruits of plants. For commercial use, com is the principal source, though wheat and potatoes are also used. Starch is extracted by grinding with water, filtering, centrifuging, and drying, a process which yields starch in a granular form. 

In terms of the average fi om 20 mature fiiiits, floss silk, seeds and fruit coat were isolated, the ratio being 14 %, 15 % and 71 % respectively. The filaments of floss silk on submission to microscopy, showed mainly unicellular trichomas, some of them being formed by two cells. The presence of lignin in the filaments was suggested by the characteristic reaction with phloroglucinol hydrochloride. 

Specimens of the pollen-feeding staphylinid beetle Eusphalerum minutum were found in cantharidin traps, which indicates that they are canthariphilous [121]. In addition, they contain small amounts of cantharidin 48, which is accompanied by palasonin 49. Palasonin has been previously only known from seeds and fruits of the Indian shrub Butea frondosa (Leguminaceae [122]). 

Defensive Compounds. Clerid beetles such as Trichodes apiarius were found to contain considerable amounts of cantharidin 48, accompanied by small to minute amounts of palasonin 49 [ 122,265]. Previously, the latter has been known only from seeds and fruits of the Indian shrub, Butea frondosa (Leguminaceae). It is suggested that these predatory beetles feed on cantharidin producing oede-merid and meloid beetles, see below. Several clerid species are canthariphilous [266,267],... 

Only 15 newly reported simple dihydroflavonols are listed in Table 15.9. Several of the compounds are just simply the C-3 epimers of known (2i ,3i )-dihydroflavonols, e.g., (2R,3S)-3-hydroxy-5,7-dimethoxyflavanone (329) from the fern Woodsia scopulina (Dryopterida-ceae), (2i ,3S)-3,5,3, 4 -tetrahydroxy-7-methoxyflavanone (3-epipadmatin, 333) from Inula graveolens (Asteraceae),(2i ,3S)-3,5,3 -trihydroxy-7,4 -dimethoxyflavanone (337) from Lannea coromandelica (Anacardiaceae), and (2i ,3S)-3,5,7,3, 4, 5 -hexahydroxyflavanone (hovenitin III, 338) from the seeds and fruits of Hovenia dulcis (Rhamnaceae). The previously known (2i ,3i )-stereoisomer of hovenitin III has the trivial name ampelopsin. The same plant source has yielded the (27 ,37 )- and (27 ,3S)-epimers of 3,5,7,4, 5 -pentahydroxy-3 -methoxyflavanone, which are known as hovenitins I (340) and II (341), respectively. ...

Essential oils are especially important in mutualistic relationships between plants and insects such as pollination and seed and fruit dissemination (37,45,77-79). In these instances essential oil components serve as attractive substances for the plant. These compounds vary widely in composition but contain most of the chemical types described above. In some cases even volatile amines and skatole are involved, as in the pollination of Sauronatum guttatum (Araceae) (80). 

The aromatic, warm, and sweetish odor and taste of the seed, leaves, and stem arises from the presence of a volatile oil that contains anethole p-propenyl phenylmethyl ether, C3H5C6H4OCH3), the derivatives of which (anisole and anisaldehyde) are used in food flavoring, particularly bakery, liqueur, and candy products, as well as ingredients for perfumes. For commercial production of anise oil, the seeds and the dried, ripe fruit of the plant are used. Anise oil. a colorless to pale-yellow, strongly refractive liquid of characteristic odor and taste, is prepared by steam distillation of the seed and fruit. The oil contains choline, which finds use in medicine as a carminative and expectorant.

It is important to purify proanthocyanidins, particularly for determining their conversion yield. It is also advantageous to do so to eliminate extraneous material that might otherwise react with the proanthocyanidins. A combination of liquid-liquid extraction and adsorption chromatography is effective in removing impurities. The use of chloroform in liquid-liquid extraction is very effective in removing fat-soluble compounds such as carotenoids, chlorophyll, oils, and waxes. These compounds would be expected in leafy plant tissues (carotenoids and chlorophyll) as well as seeds and fruits (oils and waxes). Ethyl acetate is effective in the selective removal of flavan-3-ol monomers, which are also typically present with proanthocyanidins. 

Charring is known to preserve aspects of the physical structure of wood, seeds, and fruit (42). Srinivasan and Jakes (43) have shown that in charring some aspects of the physical shape of Indian hemp fiber are retained. In the carbonization of wood, Ercin et al (44) report the loss of cellulose, hemicellulose and lignin infrared absorbance bands in the range of 1300-1000 cm-1 and the appearance of two new bands at 1250 cm 1 attributed to the asymmetric C-O-C and at 1450 cm-1 attributed to aliphatic C-H bending. 

A series of proteins, i.e., a-trichosanthin (a-TCS) isolated from the root tubers of Trichosanthes kirilowii, MAP30 isolated from the seeds and fruits of the bitter melon Momordica charantia, GAP31 from Euphorbiaceae himalaya seeds (Gelonium multiflorum), and DAP30 and DAP32 from carnation leaves (Dianthus caryophyllus), have been described to inhibit HIV infection,... 

This vinaigrette works especially well with the nuts, seeds, and fruit that adorn this salad. 

Vermouth is officially classified as an "aromatized fortified wine," referring to its derivation from a white base wine fortified and infused with a proprietary set of different plant parts barks, seeds, and fruit peels. These are collectively termed botanicals. Vermouths are particularly popular in Europe and in the United States (Amerine et al., 1980 Griebel, 1955 Panesar et al., 2009). The term "vermouth" is derived from the German word for wormwood Wermut. It is supposedly derived from Wer (man) and Mut (courage, spirit, manhood Pilone, 1954). When vermouth was introduced into Bavaria in the first half of the seventeenth century, by the Piedmont producer Alessio, Artemisia absinthium was probably translated literally as Wermutwein. When it reached France, it was changed to vermouth (Liddle and Boero, 2003).
