Compound quills, measuring 42 ins. long (just over 1 m), are sorted into grades according to the thickness of the hark. Three main qualities are exported: the 'Tine' or 'Continental' grades, the intermediate `Mexican' grades, and the 'Hamburg' grades.
Chinese cassia has been simplified during the twenty years (1954-74) during which this product was prohibited from the US market. Formerly, two grades of broken quills of Kwantung cassia (cassia iignea) and three grades of whole quills of the superior Kwangsi cassia, all differing in thickness of the bark were,offered, but Chinese cassia is now available only in two forms, whole quills and broken (No. 1 and No. 2, the latter being cheaper), either scraped or unscraped according to demand. The quality of the cassia depends upon its colour, its thickness and its oil content.
Kwantung cassia has an oil content of at least 1.7 ml per 100 g, and Kwangsi 3.4 to 4.0 ml per 100 g, according to information provided in 1974 by the Native Product Corporation, Peking (via the British Embassy). This contrasts with Landes (1951), who reported that best quality Kwangsi cassia contained 2 to 2.75 per cent volatile oil and Kwantung 1.0 to 1.2 per cent.
The spices are prepared and supplied to the market in various forms, the most elaborate type of product being the compound cinnamon quills from Sri Lanka.
The harvesting and preparation of cinnamon in Sri Lanka is generally undertaken for a farmer by contract peelers, usually a group of two families. Sufficient material is cut for a day's peeling, the working day being from about 6 a.m. to 7 p.m. Stems, measuring 1.2-5.0 cm in diameter, are cut early in the morning and the twigs and leaves are detached; the last may be retained for distillation purposes. The cut stems are then bundled and are transported by bullock cart to the peeling shed.
The Korintji and Padang (syn. Batavia) forms are graded by appearance into A, B, C and D types according to length, colour and quality, and are sold on their content of volatile oil. The USA is the main importer of Indonesian cassia, and experience there shows that the volatile-oil content usually varies between 1.3 per cent for Korintji C and 4 per cent for Korintji A, and between 1 per cent for Batavia C and 2.7 per cent for Batavia A. There is one other grade, Batavia AA, where the oil content is of little importance since the product is sold (in the USA) for packing in glass bottles where appearance is all-important.
