How many pods per poppy plant

Table Comparison of alkaloids identified on harvested and thermally processed poppy seeds. This update related to the detection of morphine, codeine, oripavine, noscapine, and papaverine in poppy seed samples whereas, the previous report related only to the levels of morphine entering the food chain.

Codeine values were given in relation to morphine equivalents, using a conversion factor of 0. Noscapine and papaverine were considered in the most recent publication however, the data that was available to the EFSA did not allow for a hazard characterization but they did conclude that the presence of these compounds would not present a health concern.

In relation to the presence of thebaine and oripavine not included in the work of this paper , it was concluded that there was insufficient data to make any assessment. Based on these updated EFSA findings, the presence of the morphine and codeine in the poppy seeds analyzed in this work, would still would still fall below the recommendations outlined.

There is also little or no information on packaging of poppy seeds regarding what, if any, treatment has taken place prior to packaging. Since the ingestion of poppy seeds has been used as reasons for failure of workplace drug testing and roadside drug testing, more should be done to ensure as much information as is possible is available on the preparation methods of the seeds.

Eur Food Res Technol. International Narcotics Board Indian cuisine uses ground white poppy seeds to thicken and flavor traditional sauces and stews. In the US, poppy seeds are usually paired with lemon in sweet pastries like muffins and scones, but are also used in savory applications like salad dressings and bagel toppings.

Because they pair so well with lemon, they also make for an interesting addition to simple pasta dishes with garlic, lemon, and herbs. Not only are poppy seeds a versatile ingredient in cooking and baking, but they are also a nutritionally dense little seed. Poppy seeds are rich in fiber, essential omega-6 fatty acids, calcium, magnesium, manganese, phosphorus, thiamin, folate, and zinc.

These are carefully chosen capsules, which were obtained on the orders of west German manufacturers of opium products. This average content varies considerably - i. An aqueous decoction of 50 g of poppy capsules, for example, corresponding to a volume of roughly cc of the broken capsules, with 1, cc of acidified water, would give no more than about cc of filtrate, which would contain roughly a quarter, or 0. The relative morphine content of this solution would thus be 0.

In order to obtain the doses of morphine required for an addict, this decoction would have to be consumed by the litre. Since, however, the morphine content of the capsules varies and the degree of extraction resulting from decoction is not constant owing to various factors such as the degree of crushing, the pH value, etc. Apart from small quantities of morphine, this decoction also contains other alkaloids and extractive by-products which have undesirable subsidiary effects and a bad taste.

Addicts, however, require a measurable and rapid effect. This, in fact, is the reason why so far as is known no morphine addicts - including those, if any, who live in the very midst of poppy-growing areas - have chosen to eat poppy capsules or to drink decoctions produced from them. For these reasons poppy capsules do not constitute a danger for addicts, a fact borne out by many years' experience.

The most important danger of the abuse of poppy straw would, however, be if it were to be used by clandestine manufacturers in the extraction of morphine. Kabay's original technique for the processing of poppy straw [ 8 ] has been the subject of the following critical analysis contained in the publication by H. Let us take a morphine factory with an annual output of 1, kg, i. The straw is extremely bulky, occupying a space which is at least ten times its own weight 17, cbm even if pressed. As farmers do not store this worthless material in their sheds, the processing factory must buy the straw immediately after the harvest and provide storage room in which it can be protected against humidity.

If the straw is piled up 6 m high, for example, a storage shed x 30 m in area and at least 8 m in height will be required. To obtain the annual supply, very large van loads would be needed. A considerable amount of costly manual labour or expensive handling equipment will be required to unload and stack the drug. This quantity must be crushed, pastified, lixiviated by an acid extracting agent, filtered and rewashed; moreover, arrangements must be made for the daily disposal of the drug extracted, because during the hot season it rapidly ferments and produces an unbearable stench.

No more than a passing reference may be made to the difficulties arising out of the use of diluted acids as extracting agents. Even if wooden vessels are largely used for the extraction products, the problem of providing acid-proof fittings and joints for the individual appliances remains.

The daily processing of the above quantities of liquid, the evaporation of not less than 30 cbm a day the minimum quantity if counterflow is available and the handling of not less than 15 cbm of moist sediment make considerable demands on the equipment.

Industrial chemists will have no difficulty in appraising the very different situation obtaining in the manufacture of an equivalent amount of morphine from opium, where 40 kg of 12 per cent opium is used per day, yielding roughly liters of liquid substance. The improved Kabay technique no longer uses poppy straw, but poppy capsules [ 1 ] ; however, here too the considerably diluted extracts have to be carefully evaporated in large distillation installations.

This concentrate must subsequently be treated with solvents and be reconcentrated. Only then can the raw morphine be precipitated by means of alkalies. In order to manufacture 10 kg of morphine in the form of raw morphine, here, too, 80, kg of poppy capsules with a morphine content of roughly 0.

For the first extraction of the above amount of poppy capsule approximately 25 times its weight of water - i. The more effective method of the firm of Hoffmann La Roche [ 9 ] operates similarly with an aqueous calcialkaline extraction and subsequent liquid-liquid extraction of the weak extracts with organic solvents that do not blend with water. According to the method of the firm of E. Merck, the alkalized poppy capsules are extracted by a circulation process involving organic solvents, the extracts being thereafter treated with acidified water.

However, in the case of this process, too, the size of the equipment must correspond to the large quantities of raw material required.
