PART I
Food in general is perishable (perishable), due to moisture contained in it as a major factor causing damage to the food itself. The higher wullenwever the moisture content of a food, the more likely the damage either as a result of internal biological activity (metabolism) as well as the entry of microbes destroyer. The criteria can be used to determine whether the food is still worth consumed, appropriately difficult to implement because it involves nonteknik factors, socio-economic, and culture of a nation. Ideally, food should be: free of pollution at each stage of production and handling of food, free from chemical changes and physical, free of microbes and parasites that can cause disease / decay (Winarno, 1993).
Act No. 7 of 1996 states that the quality of food consumed must meet several criteria, among which are safe, nutritious, high quality, and can be afforded by the public.
Additional treatment of food is a process of adding other substances that are either natural or chemical that aims to create a food to be more durable when it is compared with the usual.
The main goal is to improve the appearance of waxing fruit to make it more interesting, and can extend the shelf. Fruit waxing results will be more shiny, withering and wrinkles on the skin is also inhibited. Waxing can also serve to reduce weight loss, cover wounds or scratches on the surface of the fruit, preventing wullenwever mold, decay and discoloration of the fruit, wullenwever because the application is often accompanied by the provision waxing a fungicide, bactericide or growth regulators.
Traditional waxing wullenwever done using cottonseed oil or peanut oil but is now a common wullenwever way is to use a wax emulsion. Wax (wax) are esters of long-chain fatty acids with long-chain monohydric alcohols or sterols. Candles are used for coating must meet several requirements, namely:
Utilization waxing on new fruit at harvest. Usually done on fruit or fruit merchant Export / Import. Special Export / Import, fruit crops was likely preserved former first before it is sent to the destination country. Typically, the fruit is coated with a type of wax will prevent evaporation during the process of decay of the fruit. Wax layer is usually found in imported fruits such as orange, apple, pear, mango etc.
Before waxing, fruits washed with a soft foam to remove dirt on the skin surface, then drained to dry. The technique is most popular or commercial spray or dipped. After waxing, the fruit is drained before it is stored or marketed. Waxing is usually accompanied by low temperature storage to extend the shelf.
Treatment of a given layer of wax fruit before consumption should be washed with soap. Without soap, impossible layer of oil on the wax coating can wear off. Once washed, dried fruit should be. If it is dry, store in the refrigerator. Wrap in plastic fruit servings as needed. Plastic storage should not often open the lid, so that the fruit will be lama.Contoh fresh vegetables and fruits are given a waxing treatment;
o Add trietanolamine, continue diatud and the temperature is kept constant
To get a wax emulsion with the desired concentration is done dilution with water (not hardness). To use the wax emulsion should be used fresh. Fruits and vegetables that have been drained put in a wire basket and then dip it in the wax emulsion (concentration of 6 and 12%) until everything terendamselama30-60detik.
Waxing is very dangerous to the health of the body, because your body takes longer to digest wax. If these substances continue to accumulate in the body, our chances of developing cancer is very high. For example, cancer wullenwever of the liver, intestine, or leukemia.
Wax candles or as a preservative in fruit Consuming fruits are very good for our bodies. Maybe you've learned a wine to taste and know the taste of the wine. But should wash before consuming. If you frequently consume apples, pears, or grapes, surely you've seen the whitish color of the fruit, and if they are so slippery.
That wax or wax that is in the skin layer of the fruit. Wax or candles are often used to preserve fruits. The nature of water-resistant wax works in order that the liquid in the fruit is not fast mengua
