Terra neem oil and neem cake is manufactured by TCP (Temperature controlled process) method. We are not using any chemicals or solvents for extraction of neem oil, this process ensures the availability of all the active ingredients of the Neem seed’s kernel in the Terra neem oil and neem cake as it is. Terra neem oil minimum assurance of azadirachtin is 3500 ppm and Terra Neem cake azadirachtin is 1000ppm.
| Parameter/Stage | Commercial Neem Oil | Terra Neem® Oil | Remarks |
|---|---|---|---|
| Raw Material | Neem fruit seeds | De pulped Neem seeds | Neem fruit seeds are cheaper |
| Processing of raw material | Little or no processing | Removal of contaminants and removal of husk to obtain neem kernels | The kernels form only 20 – 22% by weight of neem fruit. |
| Oil extracted by crushing | The entire fruit with decaying pulp and outer shell | Oil is produced by crushing kernels only .By Patented method . Terra Group is the only group processing neem oil with Indian Traditional way without heat and Chemical . | Terra Neem Oil has high azadirachtin content and nil aflatoxin. Before every shipment The Terra neem oil will be tested by University Of madras and provide Certificate . |
| Temperature Control | High temperatures used for obtaining higher yield in oil extraction. The azadirachtin content is consequently low. | Crushed by patented Indian traditional way without heat and chemical , Known as Natural Cold processing method . | Terra Neem Oil has a much higher content of active liminoids with naturally |
| High performance liquid chromatography (HPLC) tests. (Azadirachtin) | Nil or once every few years. | Each batch of Terra Neem Oil is tested by HPLC to determine the azadirachtin content. The minimum azadirachtin content is 3000 ppm. Certain batches have registered readings as high as 4000 ppm. | Rigorous testing ensure, uniform quality as far as the azadirachtin content |
| High performance liquid chromatography (HPLC) tests. Nimbin and Salanin | Nil. | Each batch of Terra Neem Oil is tested by HPLC to determine the nimbin and salanin content.The minimum nimbin content is 4000 ppm. The minimum salanin content is 6000 ppm. | Nimbin and salanin are two other active ingredients which are responsible for neem’s anti fungal and anti bacterial activity. |
| Aflatoxin detection | Nil. | The batches are then tested by High Performance Liquid Chromatography to detect aflatoxin as per EU norms Aflatoxin B1 less then 2 parts per billion Total aflatoxin less than 4 parts per billion | Aflatoxin detection is mandatory for several applications. |
| Dosage for foliar spraying | 3%. Even this dosage does not ensure protection against various pests, as the active ingredient may or may not be present in the oil | Concentrations of 0.3% to 0.5% are effective against a host off pests. | Terra Neem ™ Oil can be emulsified and used directly as a foliar spray for protection against several pests. |
| Colour and clarity | Turbid with suspended matter | Clear | Terra neem oil has a better appearance. |
| Parameter/Stage | Commercial Neem Cake | Terra Neem Cake | Remarks |
|---|---|---|---|
| Raw Material | Neem fruit seeds | De pulped Neem seeds | Neem fruit seeds are cheaper |
| Processing of raw material | Little or no processing | Removal of contaminants and removal of husk to obtain neem kernels | The kernels form only 20 – 22% by weight of neem fruit. |
| Pulp/ flesh of seeds | Used. Has no azadirachtin content. Has little or no use in fertility. The decaying pulp can result in the presence of aflatoxin | Not used | Commercial cake can have aflatoxin |
| Husk/ Shell | Has no fertility. Forms 25% by weight. | Not used. Removed by willowing. | Terra Neem Oil has a much higher content of active liminoids with naturally |
| Kernels | Forms only 20–22% of the feed stock. | Pure kernels used | The kernels contain azadirachtin and other liminoids which prevent attacks by parasite nematodes. |
| Contamination by inorganic, vegetable and animal matter. | Present | Absent | Presence of contaminants in commercial cake can lead to the introduction of new insect pests, through larvae in the commercial grade cake. |
| Aflatoxin detection | Nil. | The batches are then tested by High Performance Liquid Chromatography to detect aflatoxin as per EU norms Aflatoxin B1 less then 2 parts per billion Total aflatoxin less than 4 parts per billion | Aflatoxin detection is mandatory for several applications. |
| Oil content | Generally nil. No value guaranteed. Cake can sometimes be deoiled cake. | Minimum oil content 6% | Azadirachtin present in oil. Deoiled cake has no effect on parasite nematodes. |
| Azadirachtin content | Nil. Not specified | 1000 ppm minimum. Tested by high performance liquid chromatography | Azadirachtin controls parasite nematodes and other pests. |
| Aflatoxin detection | Not conducted | Nil. Tested by Thin Layer Chromatography. | |
| Other nutritive values | Sometimes specified | Specified | |
| Sampling | Not specified | Samples drawn from every batch of 3000 kg., tested and recorded. | The batch numbers are clearly mentioned for |
| Dosage | Generally @ 1000 kg. per hectare | Dose of 250 kg. of Terra Neem Cake has the same effect as 1000 kg. of commercial cake | its high efficacy at lower dosages, is actually cheaper than commercial neem cake |
