Capsicum Oleoresin is prepared by extracting the crushed capsicum (Capsicum Annum Linn) with volatile solvents by percolation method. It contains the pungent principles, capsicin not less that 8 percent. It also contains the red colouring matter called Capsanthin. This product is a powerful irritant and a carminative, which is also used as a counter irritant in lumbago and neuralgia. It can also be used to treat stomach ache that involves poorly functioning stomach muscles and as an antibacterial agents.
Extraction of oleoresin capsicum from peppers involves finely ground capsicum, from which capsaicin is extracted in an organic solvent such as ethanol. The solvent is then evaporated, and the remaining wax like resin is the oleoresin capsicum. An emulsifier such as propylene glycol is used to suspend the OC in water, and pressurized to make it aerosol in pepper spray. The high performance liquid chromatography (HPLC) method is used to measure the amount of capsaicin within pepper sprays. Scoville Heat Units (SHU) are used to measure the concentration or "heat" of pepper spray.
A synthetic analogue of capsaicin, pelargonic acid vanillylamide (desmethyldihydrocapsaicin), is used in another version of pepper spray known as PAVA spray which is used in the United Kingdom. Another synthetic counterpart of pepper spray, pelargonic acid morpholide, was developed and is widely used in Russia. Its effectiveness compared to natural pepper spray is unclear.
Pepper spray typically comes in canisters, which are often small enough to be carried or concealed in a pocket or purse. Pepper spray can also be bought concealed in items such as rings. There are also pepper spray projectiles available, which can be fired from a paintball gun. It has been used for years against demonstrators.
Derived from chilli peppers, oleoresin capsicum is the active ingredient in pepper spray and in some topical pain relievers.

Sweet marjoram: Origanum (O) hortensis (orMajoranahortensis).
Potmarjoram: O.onites
Wildmajoram: O.vulgare.
Syrian majoram is called zatar
Family: Labiatae or Lamiaceae (mint family).
In Europe, marjoram was a traditional symbol of youth and romantic love. Used by Romans as an aphrodisiac, it was used to cast love spells and was worn at weddings as a sign of happiness during the middle Ages. Greeks who wore marjoram wreaths at weddings called it “joy of the mountains.” It was used to brew beer before hops was discovered, and flavored a wine called hippocras. A cousin of the oregano family, marjoram originated in Mediterranean regions and is now a commonly used spice in many parts of Europe. Called zatar in the Middle east and often mistaken for oregano, it is also a popular spicing in Eastern Europe.
Origin and Varieties
Marjoram is indigenous to northern Africa and southwest Asia. It is cultivated around the Mediterranean, in England, Central and Eastern Europe, South America, the United States, and India.
Description
Marjoram leaf is used fresh, as whole or chopped, and dried whole or broken, and ground. The flowering tops and seeds, which are not as strong as the leaves, are also used as flavorings. Sweet marjoram is a small and oval-shaped leaf. It is light green with a greyish tint. Marjoram is fresh, spicy, bitter, and slightly pungent with camphor like notes. It has the fragrant herbaceous and delicate, sweet aroma of thyme and sweet basil. Pot marjoram is bitter and less sweet.
Chemical Components
Sweet marjoram has 0.3% to 1% essential oil, mostly monoterpenes. It is yellowish to dark greenish brown in color. It mainly consists of cis-sabinene hydrate (8% to 40%), -terpinene (10%), a-terpinene (7.6%), linalyl acetate (2.2%), terpinen 4-ol (18% to 48%), myrcene (1.0%), linalool (9% to 39%), -cymene (3.2%), caryophyllene (2.6%), and a-terpineol (7.6%). Its flavor varies widely depending on its origins. The Indian and Turkish sweet marjorams have more d-linalool, caryophyllene, carvacrol, and eugenol. Its oleoresin is dark green, and 2.5 lb. are equivalent to 100 lb. of freshly ground marjoram. Marjoram contains calcium, iron, magnesium, phosphorus, potassium, sodium, vitamin A, vitamin C, and niacin.
Culinary uses of Marjoram
Marjoram is typically used in European cooking and is added to fish sauces, clam chowder, butter-based sauces, salads, tomato-based sauces, vinegar, mushroom sauces, and eggplant. In Germany, marjoram is called the “sausage herb” and is used with thyme and other spices in different types of sausages. It is usually added at the end of cooking to retain its delicate flavor or as a garnish. It goes well with vegetables including cabbages, potatoes, and beans. The seeds are used to flavor confectionary and meat products.

Kiwi :

The world's largest consumption of the first 26 kinds of fruit, kiwi is the most comprehensive. The content of Vc, Mg and trace elements in kiwifruit fruit was the highest. Among the top three low-sodium and high-potassium fruits, kiwi is at the top of the list because it contains more potassium than bananas and citrus. At the same time, the content of Ve and Vk in kiwifruit was determined to be excellent, low in fat and no cholesterol. According to the analysis, kiwi fruit vitamin content per 100 grams of fresh samples in general 100-200 mg, high up to 400 mg, about 5-10 times the citrus; sugar 8-14%, acid 1.4-2- 0%, but also with tyrosine and other amino acids 12 species.

kiwi fruit contains a wide range of nutrients, most of the fruit is rich in one or two nutrients, but each kiwi can provide 8% DV folic acid, 8% DV copper, 8% pantothenic acid, 6% Fresh, 4% DV iron and vitamin B6, 2% DV phosphorus and Va as well as other vitamins and minerals. Kiwi in addition to kiwi alkali, proteolytic enzymes, tannin pectin and sugar and other organic matter, as well as calcium, potassium, selenium, zinc, germanium and other trace elements and the human body needs 17 kinds of amino acids, but also rich in vitamins, , Fructose, citric acid, malic acid, fat.

A kiwi can provide a day more than twice the demand for vitamin C, known as the "king of fruit." Kiwi also contains good soluble dietary fiber, as the fruit of the most eye-catching place is contained in its superior antioxidant properties of plant chemical substances sod, according to the US Department of Agriculture research report, kiwi comprehensive antioxidant index in the Fruits among the top, second only to the thorns, blueberries and other small fruit, far stronger than apples, pears, watermelon, citrus and other daily fruits. And blueberries belong to the second generation of fruit is quite representative. Compared with sweet orange and lemon, kiwi fruit contains vitamin C ingredients are two times the first two fruits, so often used to fight against scurvy. Not only that, kiwi can stabilize mood, lower cholesterol, help digestion, prevent constipation, as well as thirst and diuretic and protect the role of the heart.
