Horticultural Maturity Indices Harvest maturity is based on the root size desired by the market and ranges from 6 to 18 mo after the stem sections are planted. The main stem is often trimmed to approximately 1 m (39 in) in height a few days before harvest. Plants are manually pulled, or the root zone mechanically undercut to facilitate plant removal, and individual roots are cut. Cassava roots are turgid at harvest and must be handled carefully to avoid splitting the periderm. Harvest may be delayed until market, processing, or other conditions are favorable, since cassava roots can be stored in the ground for up to 24 mo. Scientific Name and Introduction Cassava (Manihot esculenta Crantz) is a woody perennial shrub of the Euphorbiaceae family and is native to the Amazon region and Central America. It is widely grown throughout the tropics for its starchy root (Rubatsky and Yamaguchi 1997). Cassava is called "yuca" in Spanish, "mandioca" in Portuguese, "cassave" in Haitian Creole, and "manioc" in French. Cultivars are classified into two groups based on the amounts of hydrogen cyanide present. These latter types are processed into products including flour (from coarse to finely textured), tapioca starch, and fermented starch. In 2002, 184 million tonnes of cassava was produced worldwide; major producers were Africa (Nigeria) (99 million tonnes), Asia (52 million tonnes), and Latin America and the Caribbean (32 million tonnes). Cassava is adapted to semiarid climates and has been a traditional crop for subsistence farmers, though it is increasingly cultivated as an agronomic crop. Commercially, roots are cleaned by brushing, rinsing in water, surface-drying, and coating with paraffin wax prior to packing in corrugated cartons. Precooling Conditions Room cooling is generally sufficient, provided that the roots are not held too long at ambient temperatures prior to or after packing. Quality Characteristics and Criteria Fresh cassava roots are highly perishable under ambient conditions, becoming unmarketable in 3 days or less. However, with proper handling, fresh roots can be stored up to 30 days, permitting export by marine container. The roots should be firm, turgid, fairly straight, and free from mechanical injury, decay, and vascular streaking. A water-based carnauba wax maintained postharvest quality equivalent to paraffin wax (Sargent et al. Physiological Disorders Vascular streaking appears as blue or purple spots when the root is cut transversely and is the result of oxidative processes in the vascular bundles. It typically develops at wound sites, such as at the apical end where the root is cut at harvest or under breaks in the peel that can occur during careless handling. Vascular streaking is related to oxidation of scopoletin, a phenolic compound (Wheatley and Schwabe 1985). Retail Outlet Display Considerations Cassava is normally displayed in bulk and should be held in refrigerated display cases.

Ripening rates and characteristics of the fruit vary to some extent between lots depending on cultivar bacteria use restriction enzymes to 600mg linezolid sale, country of origin infection 3 weeks after c-section order generic linezolid pills, weather conditions during the growing of the fruit antibiotics for acne how long should i take it purchase 600mg linezolid overnight delivery, temperatures during handling and transit treatment for dogs fleas buy cheap linezolid 600 mg, and maturity of the fruit. Hard-green fruit (less full) will take longer to ripen than more advanced and full fruit. The lower value of the range is for mature-green fruit, and the higher value is for ripening fruit. Physiological Disorders A condition known as "maturity bronzing" or "maturity stain" has been observed in Australia and Central America at certain times during the year, 20 to 30 days before harvest (Stover and Simmonds 1987). This disorder has been associated with water deficits at bunch emergence during rapid fruit growth under very humid and hot conditions (Daniells et al. Postharvest Pathology the main postharvest diseases of bananas and plantains are crown rot-a disease complex caused by several fungi (Colletotrichum musae, Fusarium semitectum, Fusarium pallidoroseum, Lasiodiplodia theobromae, Botryodiplodia theobroame, Ceratocystis paradoxa, Verticillium sp. Though it can appear on green fruit, it is more apparent in ripening fruit as numerous small, dark, circular spots. Crown-rot organisms normally enter after harvest, usually as a result of mechanical injury to the fruit. The potential of this fungal disease is such that a flourishing banana industry can be destroyed within a few years. Fruit symptoms include premature ripening, buff-colored pulp, and increased susceptibility to chilling injury. Preventive and control measures to reduce decay incidence begin with strict sanitation in plantation and packing plant, postharvest treatment with systemic fungicides, minimizing mechanical damage during handling, prompt cooling of fruit to lowest safe temperature, and expediting transport to final destination. Acknowledgments Some of the information in this chapter was from the University of California, Davis, website "Fresh Produce Facts" at postharvest. Suitability as Fresh-Cut Product Bananas and plantains are not good candidates for fresh-cut processing because of their very high oxidation and browning potential (John and Marchal 1995). Special Considerations Mechanical damage in bananas and plantains takes several forms that vary in importance depending on the perceptions of consumers. Export markets for bananas require a blemish-free fruit, though requirements are a bit more relaxed for plantains. Bruising of the pulp is undesirable and cannot always be detected from damage to the peel (Akkaravessapong 1986).

Scientific Name and Introduction Fresh snap or common beans (string beans, yellow wax beans, green beans) (Phaseolus vulgaris L. Fresh pod beans are available from many production areas in the United States, but in the winter months they are produced mainly in Florida and Mexico. This is especially beneficial in dry climates where dehydration is a concern and in situations where evaporation of surface moisture occurs rapidly after cooling (for example, beans packed in wirebound crates). Hydrocooling is very rapid, but significant postharvest decay can occur if the product remains wet after cooling. Efficient cooling is achieved without leaving free moisture on beans, but high relative humidity must be maintained to reduce excessive water loss (Boyette et al. Quality Characteristics and Criteria Beans should be well-formed and straight, bright in color with a fresh appearance free of defects, and tender (not tough or stringy) but firm.

Metabolism-The physical and chemical changes that allow the body to grow zinnat antibiotics for uti buy linezolid 600 mg low price, function antibiotic generic names cheap linezolid 600 mg with visa, and to convert food into energy antimicrobial bit in mouthwashes generic 600mg linezolid free shipping. One major drawback to trying alternative cancer therapies is that opportunities may be lost for timely application of other antibiotics for strep viridans uti 600 mg linezolid visa, more effective therapies. Side effects Concern has been expressed that patients on some metabolic diets may risk electrolyte imbalances or even death. Further concern exists about the safety of enzyme injections and the toxicity of megavitamin therapy. Research & general acceptance Most metabolic therapies for cancer are well outside the comfort zone of traditional medical practitioners. Some proponents have experienced considerable opposition from regulators and law-enforcement officials. Training & certification Metabolic therapies are usually offered in small medical clinics that have developed their own treatment protocols. A number of these clinics are clustered in northwestern Mexico, just a few miles from the United States border. There, practitioners are easily accessible to visiting Americans, yet outside the jurisdiction of United States regulators. It is the source of sulfur for numer1349 Methionine ous compounds in the body, including the amino acids cysteine and taurine. The body uses sulfur to influence hair follicles and promote healthy hair, skin, and nail growth. Methionine is a lipotropic-a nutrient that helps prevent fat accumulation in the liver, and usually helps detoxify metabolic wastes and toxins. Methylation reactions are essential for the detoxification of harmful products of metabolism, and the synthesis of numerous physiological agents including neurotransmitters, cartilage, and glutathione. It can combine with toxic substances to form water soluble compounds that can be excreted through the kidneys. Methionine itself has a protective effect on glutathione and prevents depletion during toxic overload, which can protect the liver from the damaging effects of toxic compounds. It also increases membrane fluidity, restoring several factors that promote bile flow. It is essential for the regeneration of neuron axons following injury, and for the formation of myelin sheaths (a fatty substance) that surround axons. Preparations containing both methionine and acetaminophen have been formulated for use in situations where overdose may occur. Mothers whose methionine intake is adequate during the period from three months prior to conception through the first trimester of pregnancy have a significantly lowered risk of having a baby with a neural tube defect. Oral doses of methionine have also been given to lower urinary pH and to help in the treatment of liver disorders. Methionine in combination with several antioxidants may reduce pain and recurrences of attacks of pancreatitis (inflammation of the pancreas). As of 2002, cancer researchers are studying the role of methionine in a special diet for patients diagnosed with colon cancer. Patients with acidosis (condition of increased acidity in body fluids) or established liver insufficiency should not take methionine, and it should be used with caution in patients with severe liver disease. Women who are healthy and eat a well-balanced diet do not require methionine supplementation during pregnancy or while breastfeeding. Precautions Homocysteine is an amino acid that the liver produces after ingesting methionine. Increased methionine intake, in the presence of inadequate intake of folic acid, vitamin B6, and vitamin B12, may increase the homocysteine in the blood and increase the risk of heart disease, or stroke. A doctor should be consulted to determine if any nutrient supplementation is needed. Homocystine is the amino acid formed by the oxidation of homocysteine; homocystinuria is an inherited disorder in which there is excess homocystine in the plasma that is excreted in the urine. Supplementation of up to 2 g methionine daily for long periods of time has not produced any serious side effects. It is a perennial plant with twisting, climbing vines that grows in warm tropical climates.

The entire cluster can be harvested antibiotic resistance and meat purchase linezolid with paypal, or only mature berries can be picked over several harvests antibiotic spectrum discount 600 mg linezolid. At maturity antibiotic resistance vertical horizontal discount 600 mg linezolid with visa, gooseberry cultivars may be green antibiotic resistance and factory farming 600 mg linezolid fast delivery, white, yellow, or various shades of red (pink to purple to almost black). Since both immature (green) and ripe gooseberries are used, harvest maturity depends entirely on end use (Ryall and Pentzer 1982). Green gooseberries are very firm and tart, whereas some cultivars, when fully mature and soft, are quite sweet. Elderberries are harvested in late August and September, when the fruit is sufficiently large and has changed to an acceptable purplish-black color. The fruit do not mature at the same time, so several pickings are necessary over a 1- to 2-week period (Craig 1978, Way 1981). Harvesting occurs in late August and September, depending on climate and cultivar. Postharvest decay of currant, gooseberry, and elderberry can be minimized by avoiding picking wet or overripe fruit. Processors, who use most of the commercial production, may have their own standards. Since fresh market volumes are not large, container sizes and packaging for the fresh market tend to be those used for similar but more common berries (for example, raspberries). Precooling Conditions Currant, gooseberry, and elderberry fruit are relatively perishable. Retail Outlet Display Considerations Currant, gooseberry, and elderberry should be kept in a refrigerated display but not sprinkled with water or top-iced. Postharvest Pathology the main postharvest disease is gray mold rot (Botrytis cinerea), which can appear as small brown spots on currant and gooseberry fruit (Ryall and Pentzer 1982, Dennis 1983, Harmat et al. Currant and gooseberry fruit can be susceptible to American powdery mildew (Sphaerotheca mors-uva) (Harmat et al. Fruit that become contaminated by soil splash after heavy rain are frequently infected by Mucor piriformis (Dennis 1983). Dennis (1983) also reports a fruit disease in gooseberry caused by Alternaria and Stemphyllum. If, however, the fruit is stored for a few days at ambient temperatures prior to consumption or processing, the fungus invades the pericarp tissue. Several insects can attack the fruit: currant maggot or fruit fly (Epochra canadensis) (North America), gooseberry fruitworm (Zophodia convolutella) (North America), and currant moth (Incurvaria capitella) (Europe) (Harmat et al. Diseases and insects are not generally serious on elderberries (Way 1981), perhaps because of the absence of extensive plantings. An unidentified mildew can be a problem on ripe fruit, especially if the weather is cool during ripening and there is poor air circulation around the plants (Way 1981). Birds feeding on ripe currant, gooseberry, and elderberry fruit can be a serious pest problem (Way 1981, Harmat et al. In addition to prompt harvesting of ripe fruit, various bird repellent measures may have to be considered. Quarantine Issues None 308 Suitability as Fresh-Cut Product No current potential Harmat, L. Thus, commercial production of Ribes species, especially black currant, may be banned in some U. For other varieties, dates that are harvested before reaching full maturity must be ripened artificially. Very immature dates cannot be properly ripened artificially and will thus be of poor quality. Grades, Sizes, and Packaging Dates are graded based on uniformity of color and size and extent of defects or damage, which include discoloration of the flesh, rupture of the skin, deformity of the fruit, puffiness of the skin, scars, sunburn, insect damage, decay, black scald, fermentation, improper ripening, mechanical damage, and presence of dirt or other foreign material. In general, the total amounts of sugar for different grades are usually the same when expressed as a percentage of dry weight, but the higher grades usually contain higher amounts of sugar per date. Consumer packages are widely used and consist of various sizes and shapes, including bags of transparent film and trays overwrapped with film.
