Contents vegetables preservation Key Terms References. To understand the importance of studying food ingredients should be well understood: what is food, what food, what are nutrients and how obajašnajva physico-chemical constitution of food. Therefore, we will clarify these concepts and terms.
Under the food is meant any substance vegetables preservation or product, vegetables preservation whether processed, partially processed or unprocessed, which is intended for human consumption, or could reasonably be expected to be consumed. Food includes all substances intentionally added to food during its production. The food is all you can eat and drink, and corresponds to the hygiene and quality requirements for human consumption. The food and water falls, and the so-called. process water used during vegetables preservation the manufacturing process used for mixing, dissolving, steeping or soaking. The food includes drinks, chewing gum, food additives and any other substance that is incorporated into the food during its manufacture. The food that a person consumes can be derived from: plants (fruits, vegetables, grains, legumes, oilseeds, spices, seeds of various plants, mushrooms, green algae) animals (meat, milk, eggs, honey, seafood, etc.). Others organisms (microorganisms) vegetables preservation of other origin (water).
The food does not include: animal feed, live animals (except as such are not prepared to eat), plants prior to harvest of crops, medicines and medical products, cosmetics, tobacco and tobacco products, narcotic or psychotropic substances, residues and contaminants. vegetables preservation The nutritional and biochemical terms, food is any substance that absorption in the human body contributes to the preservation of homeostasis of the body. Food into our body in order to satisfy hunger and nutritional needs oraganizma.
The daily diet of people contains more than 100,000 substances. It is necessary to know that only about 300 chemical substances classified as nutritional substances. Many of the chemical components used in feed are used for its improvement and may be helpful (and harmful). Such additives (preservatives, emulsifiers, stbilizatori, antioxidants) that improve the processing, storage and packaging of food. Also, there are natural components of the food contained in trace amounts, such as flavoring and flavori, flavorings, aromatizers, dyes, Phytochemicals and many other natural products that improve the properties, flavor and stability of food. These components do not have the energy value, but have an important role in the biological organism.
The food we eat can be fresh or processed. vegetables preservation Fresh food parts of plants (fruits, leaves, flowers) or the whole plant. From the aspect of biology fed to cells, tissues or organs of plants or animals. During processing changes the physical and chemical structure of the food but the nutritional komonente largely retained.
Food is a substance, and nutrition is a process. Nutrition is a process or a group of metabolic vegetables preservation processes occurring in the body from the moment food intake (eating) to its utilization in energy, building blocks or regulatory or protective purposes. This involves covering the body with energy, proteins, carbon hydrates, lipids, minerals and vitamins and daily intake of food to satisfy hunger and need the nutrients. Meals are maintaining homeostasis of the organism, or the natural balance in the body while maintaining normal vegetables preservation indoor environment. In other words, homeostasis means the balance and the ability to adapt the organism to changing environmental conditions and nutrition at the same time play a crucial role.
Nutrients are chemical ingredients. Substances from the foods we are eating, and when it is exploited in this way you give the body the necessary energy, component and regulatory-protective components, called nutrients. These are the basic chemical ingredients that are in the digestive tract can absorb it would then meet the metabolic needs of the body. The body is very dynamic chemically transformed into a variety of compounds that enable the proper functioning of the body. Only knowledge of the function of nutrients in the human body to conception or proper balanced diet for each age, sex, profession and so on. Proper nutrition provides the optimal performance of the human body, and is based on the concept of optimal and balanced nutrients, or the integrity of the nutritional content of food. Each nutrient has one or more of the following functions: a source of energy for metabolism or activity provides the building blocks for the protection of materials or the support body, for example. bones, muscles, tendons, skin, etc.. participates in the regulation of body processes, including metabolism, growth, reproduction and repair of damage. Nutrients vegetables preservation can be categorized as: macronutrients: proteins, carbon hydrates, lipids and water micronutrients: vitamins and minerals
