How to Teach Kids to Solve Math Word Problems Determining the nutritional content of the food you eat will allow you to better understand what comprises these foods. Knowing what food is made of is one of the first important steps in choosing to eat a healthy diet. There are two different ways that you can easily determine the exact nutritional value of your food. You do not need to use fancy equipment or perform your own science experiments to figure it out.
Roots and legumes can be important contributors of dietary proteins —especially in developing countries, where animal proteins are scarce. One potential nutritional problem of obtaining proteins from a single vegetable source is the low concentration of essential amino acids in vegetables. Twenty common amino acids are considered to be building blocks of proteins for the body.
Of these 20, the body cannot synthesize eight; these eight must be obtained from foods. Most vegetable proteins are low in one of the eight essential amino acids; for example, corn is low in lysine, and soybeans are low in methionine.
However, if proteins are obtained from a proper mixture of vegetables, there will not be a nutritional problem. It is a common misconception that fresh vegetables are always superior in nutritional value to processed vegetables.
Several investigations have shown frozen or canned vegetables can actually have higher nutritional value than fresh products. Fresh vegetables are subject to quality and vitamin losses during transportation and storage, whereas processing before these losses occur can yield a nutritionally superior product.
Research has shown that a major cause of nutrient loss in vegetables is in the draining of cooking or processing liquids. Fresh and minimally processed vegetables Harvesting and storing Most leafy vegetables that do not require harvesting by mechanical device are cooled immediately after harvest to remove field heat, sorted to remove debris, washed to remove dirt, and bundled or packed for shipping and retail.
In most cases vegetables are bundled as whole plants, since cutting will injure the cells and liberate ethylene, which promotes senescence and shortens shelf life.
Low-temperature storage is essential in the handling of quality leafy vegetables. On the other hand, storing below refrigerated temperature may lead to chilling injury of certain vegetables and to rapid loss of quality.
In developing countries where refrigeration is not available, postharvest losses of fresh vegetables can be as much as half the total harvest. For roots and legumesthe harvesting of which is normally done by machines, some sorting and grading are performed either in the field or at collection stations.
Bulk handling of these vegetables is common, and few additional steps of preparation are performed before distribution. For vegetables that need to be stored for long periods of time, treatments to avoid microbial spoilage, insects, and small-animal invasion may be necessary.
For some vegetables such as cucumbers, a washing and waxing step may be taken to improve the shelf life and the attractiveness of the produce. Packaging Provided in response to demands for convenient foods, minimally processed fresh produce has gained popularity in the marketplace. These vegetables go through additional preparation steps of washing, sorting, grading, cutting, and packaging into retail-size containers.
In order to extend the shelf life of these products, vacuum packing and modified-atmosphere MA packaging are practiced. In most cases air is replaced by an atmosphere high in carbon dioxide and low in oxygen. This modified atmosphere can slow the respiration rate and therefore the senescence of cut vegetables.
The most common products in American and European markets are various types of cut lettuces with shredded carrots, cabbages, and other vegetables. The products can be shipped by refrigerated containers to overseas locations and still have a shelf life long enough to reach consumers.
Minimally processed vegetables normally do not contain any preservatives and have not gone through any heat or chemical treatment. The disadvantage of these products is that refrigeration storage is essential, limiting its practice to developed countries.
Processing of vegetables Because of the varied growing and harvesting seasons of different vegetables at different locations, the availability of fresh vegetables differs greatly in different parts of the world.
Processing can transform vegetables from perishable produce into stable foods with long shelf lives and thereby aid in the global transportation and distribution of many varieties of vegetables.
The goal of processing is to deter microbial spoilage and natural physiological deterioration of the plant cells. Generally, the techniques include blanchingdehydrating, canning, freezing, fermenting and pickling, and irradiating.
Blanching inactivates natural enzymes that would cause discoloration and off-flavours and aromas.
It also serves to reduce the number of microorganisms and to render vegetables limp for easy packing into containers. For some vegetables, such as spinach, snap beans, and collards, the blanching step also serves to remove harsh flavours. After blanching the vegetables must go through rapid cooling in either cold water or cold air for better quality retention.Background.
The background of the workshop was the proposed EU legislation to regulate nutrition and health claims for foods in Europe. This regulation will require the development of a science-based nutrient profiling system in order to determine which foods or categories of foods will be permitted to make nutrition or health claims.
