DEFINITIONS
1. WHAT IS A SPICE?
A spice is any aromatic substance of vegetable origin used to add flavor or color to food. The word “spice” is an all-inclusive term that encompasses 3 categories: Spices, Herbs and Aromatic Seeds.
A. SPICES are derived the bark, root, fruit or berry of perennial plants, Usually grown in the tropical zones. For example: Cinnamon bark, Ginger root, Nutmeg fruit, or Black pepper berry.
B. HERBS are distinguished from spices in that they are the leaves only of annual and perennial low-growing soft-stemmed shrubs of the temperate zones. Examples are: Basil, Marjoram, Tarragon, Thyme and Rosemary.
C. AROMATIC SEEDS are the seeds of lacy annual plants. Examples are: Anise seed, Caraway seed, Coriander seed and Fennel seed.
D. We might also consider as a fourth category the Dehydrated Vegetables. Examples of these are: Onion, Garlic, Sweet bell peppers, Horseradish, Mushroom, Celery flakes and Chives. All the spices mentioned are called “Natural Spices” because, except for drying, they are completely raw and unprocessed.
2. WHAT IS A SEASONING?
A seasoning is a blend of two or more spices, herbs or seeds. It can also contain other ingredients, such as, salt, sugar, starches, flavors and various food chemicals.
3. WHAT IS AN ESSENTIAL OIL?
This is the volatile oil derived from the spice, which contains the essential odor or flavor. It is separated from the spice primarily by means of steam distillation. In the case of black pepper and ginger, the essential oils contain only the aromatic portion without the pungency or heat; the latter is provided by the oleoresin. By definition, the essential oil or volatile oil is readily vaporized at high temperatures. This is the reason for the intense aroma that we get while cooking with spices. It is because of the essential oil that spices impart their characteristic flavor to food products.
4. WHAT IS AN OLEORESIN?
This is a viscous substance containing both volatile oil and a fixed or non-volatile oil or resin. Oleoresins are prepared by the extraction of ground or cracked spices with a pure chemical solvent, such as, ethylene dichloride, which is then removed by distillation. Oleoresins impart the taste or pungency or the spice, such as, in black pepper and ginger; the color, as in paprika and tumeric; and the heat, as in the capsaicin red peppers.
5. WHAT IS A SOLUBLE SPICE?
This is a dry product consisting of spice essential oils or oleoresins coated or “plated” onto a neutral carrier, such as, salt, sugar or dextrose. When mixed with water, a soluble spice dissolves completely. Soluble spices and seasonings are used wherever the appearance of natural or ground spices is undesirable in a food product, for example, Tomato catsup, Salad dressings, and picked meat products. Soluble spices are free flowing and are designed to be pound for pound replacements for natural ground spices. They are easy to use, disperse quickly, and contribute to product uniformity. Unlike natural spices, soluble spices are not subject to insect infestation or mold. However, their flavor may be less stable due to more rapid volatilization of the essential oils.
6. WHAT IS AN EXTRACT?
This is a solution obtained by the percolation of alcohol through a substance. Commercially prepared extracts usually consist of an essential oil dissolved in alcohol and water. The common extracts used in the baking industry are: Vanilla, Orange, Lemon and Almond.
7. WHAT IS MEANT BY THE TERM GRANULATION?
This refers to the physical size of particles of spice. To measure the actual size, a universally accepted system has been devised. Under this system, particles are classified by the use of silk or woven wire cloth sieves known as screens. A 50-mesh screen has 50 square holes per linear inch. Common sizes range from 5 to 200 mesh, with the latter used primarily for mustard flours. THE LARGER THE SCREEN NUMBER, THE SMALLER THE PARTICLE SIZE. By far, the majority of the spice industry makes use of the United States Standard Testing Sieves, the dimensions of which are controlled by the American Society of Testing and Materials (ASTM). Other systems, such as, Newark, Tyler and Tensil Bolt screens, are less widely used. For ease of comparison, every sieve is marked with the size of the mesh opening in both inches and millimeters. For example, the U.S. Standard Sieve No. 35 has a mesh opening of .0197 inches or .5mm. This is equivalent to the Newark No. 38 mesh sieve, which has an opening of .0198 inches. This is also quite close in size to the Tyler No. 32-mesh sieve. Round hole screens are occasionally used for black pepper and other spices.
A. WHAT DOES THE TERM GINGER U.S. 60 MESH MEAN?
It means that the ginger is ground such that at least 95% of the spice will pass through a U.S. No. 60-mesh screen.
B. WHAT DOES THE PHRASE BLACK PEPPER 26/50 MESH MEAN?
It means that the black pepper has been cracked rather than ground and that at least 90% of the particles range in size between 26 and 50 mesh. In fact, 95% must pass through the No. 26 screen and 95% must be retained above the No. 50 screen. Thus, since only 5% may be smaller than 50 mesh, this product is essentially a dustless pepper. The correct method of particle size analysis is by means of a mechanical shaking device. Screens, which are round and stackable, are placed in the proper sequence and shaken for 10 minutes.
As an example, a typical quality assurance test would run like this: 100 grams of ground spice are weighed onto a 35-mesh screen. After shaking, 1 gram remains on top of the screen. Therefore, 99 grams or 99% of the sample passed through the screen. Result: The test shows that grinding specifications have been met and exceeded
