Quince seed

As predictable from the similarity of the properties of the two gums, quince seed gum is used in the appHcations described above for psyllium seed gum. Specific appHcations are in cosmetics and hair-setting lotions. It has also been used as an emulsifier and stabilizer in pharmaceutical preparations.

As mentioned above, the stability of colloidal metal solutions is considerably enhanced by the addition of certain organic substances or protective colloids. For example, gelatin has been frequently employed, 0-5 gram per litre of colloidal solution proving very effective in preventing the coagulation or precipitation of the metal.2 Extracts of Iceland moss3 and of quince seed 4 have also been recommended.

Other properties which are of commercial value but are peculiar to more limited groups are as follows (a) the ability of cellulose derivatives, particularly carboxymethylcellulose to adsorb onto cotton libers, forming a barrier repellent to dirt and (b) the ability of carrageenans and quince-seed mucilage to alter the aggregation of casein in milk. The last two poly-sacolloids are the only ones that seem to be absorbed by skin tissues, making them particularly effective in cosmetic and pharmaceutical preparations for topical application. 

Both psyllium and quince seeds are imported into the United States for limited, specialized uses. Almost all the psyllium seed arriving from India proceeds to pharmaceutical houses for use in laxative preparations utilizing the mucilage-containing seed husk. Quince seeds from Iran are purchased by cosmetics houses, principally for use in hand-lotions. Each user prepares his own mucilage extract directly from the seeds, as needed. Seed supplies are restricted, so that any unusual demand is reflected in increases in price.

Quince is not eaten raw, but is processed into jams, jellies and confections. They are mainly grown in southern Italy and other south European countries. Neubeller and Buchloh (1970) reported 17% fat in quince seed. The fatty acid profile of the seed oil is identical to that of apple seed oil and quince seed could be combined with apple seed for processing (Table 7.9).
