Pineapples, canned

Some horticultural crops such as sweet potatoes, bananas, and pineapples can suffer from chilling injury at low temperatures (Lee and Kader 2000). Chilling injury causes accelerated losses in ascorbic acid content of chilling-sensitive crops. Destruction of ascorbic acid can occur before development of any visible symptoms of chilling injury (Lee and Kader 2000). 

When reviewing all of the previous data, the FDA detected synthetic chemicals in virtually all the foods tested. Only corn, ham (luncheon), pineapple (canned), pinto beans, kidney beans, and chicken noodle soup were shown not to be contaminated. The fact that virtually every food we eat has been shown to be contaminated raises the following question. What synthetic chemicals are we most likely going to be exposed to if we consume a balanced diet of dairy, fruits, grains, protein, and vegetable products The answer to this question is discussed in Chapter 3.

Pineapple can often be quite tart, unless you happen to be enjoying it on a tropical island where the fruit grows and it s picked at its perfect ripeness. Heating the pineapple—in this case, grilling it— breaks down the starch into natural sugars and releases a wonderful sweet flavor. 

The pineapple plant has been an inspiration for painting, architecture and sculpture and is used on masonry pillars at the entrance of houses, villas and gardens. The stem is used by the food industry asraw material to obtain ethyl alcohol and gums. The rest of the pineapple can be used in animal feed such as silage or fresh material. The fruit is consumed fresh or in the form of ice cream, candy, popsicles, soft drinks and homemade juices. When industrialized, the results can be presented as pulp, syrup, jelly, sweets in syrup or bottled juice. In some countries, in hot and dry regions, wine is obtained with the sweet fruit. 

For the future, because of their ability to produce under arid conditions, greater exploitation of CAM plants is to be expected. As indicated by Bartholomew (1975), pineapple can be cultivated without irrigation in regions with 100 cm precipitation. In Wahiawa (Hawaii) with an annual rainfall of 100 cm and a pan evaporation of 185 cm, pineapple can yield as much as 4.4 tons ha" month" The potential for raw cellulose, combustable hydrocarbons, alkaloid drugs, and food and fiber production under marginal agricultural conditions is unlimited. 

The ester that is present in pineapples can be synthesized from butanoic acid and methanol. What is the chemical equation for the formation of this ester ... 

After all the butter has been whisked in the sauce will be creamy and warm. If pools of clear butter oil have started pooling up all over the place the sauce has broken. You failed. Actually, the sauce will still taste fine, it just won t be creamy like a snooty Frenchman would like. The sauce can be kept warm over a hot water bath or by stirring over low heat. Anyway, at this point one stirs in the soy sauce and pineapple into the sauce and drapes it over the k-bobs. Oh God is it the best flavor in the world. You have been warned ... 

Another subclass of proteases attacks internal peptide bonds and Hberates large peptide fragments. Bromelain, a plant protease derived from the stem of the pineapple plant, can even produce detectable semm proteolysis after oral adrninistration (180). Oral therapy with bromelain significantly reduces bmising that stems from obstetrical manipulations (181). Bromelain—pancreatin combinations have been more effective in digestive insufficiency compared to either pancreatin or placebo (182,183). Bromelain may also enhance the activity of antibiotics, especially tetracycline, when adrninistered concurrently (184). 

DisK Presses Figure 18-157 shows a disk press. The two disks, or press wheels, converge to a veiy narrow space at the bottom. This is the point of maximum compression, which can be more than 14 times the feed pressure. The press wheels have channels to cany the hquid from the dewatered product, and they are covered with a screen plate. Wheels 1.5 m (5 ft) in diameter are used on a large press that requires about 80 connected horsepower and produces just under 1 tonne/h (0.9 ton/h) of sohds (diy basis). Typical apphcations are fibrous materials such as coffee grounds, pineapple and citrus peels and wastes, alfalfa, and brewers spent grain. 

SEM can also be used for the interface analysis of composites. Figures 16a and 16b show the SEM of PMPPIC-treated and untreated pineapple fiber-rein-forced LDPE composites. Strong adhesion between fiber and matrix is evident from Fig. 16a, whereas Fig. 16b indicates fiber pullout [78].

Cholestyramine powder The prescribed dose must be mixed in 4 to 6 duid ounces of water or noncar-bonated beverage and shaken vigorously. The powder can also be mixed widi highly fluid soups or pulpy fruits (applesauce crushed pineapple). The powder should not be ingested in die dry form. 

Historic herbal texts can be considered both works of art and troves of information. Many of the original copies of the texts still available were hand copied and corrected as deemed necessary by the transcriptionist [21]. Frequently, the images accompanying the text descriptions were ornately hand painted. Often, these images contain such intricate detail that it is possible to accurately identify the genus and species of the plant described. For example, Figure 4.2 shows the illustration of the common pineapple from the 400-year-old Ambonese Herbal. 

Applications to and harvest of major crops such as coffee, bananas, and pineapples frequently involve procedures and equipment for which standard operating procedures have not been written. These must be identified in the planning stage, so that the Study Director or Principal Investigator can write these procedures with sufficient time to allow for review and approval. If a procedure is specific to the trial at hand, the process may be described in an addition or amendment to the protocol, but this still requires QA and management approval. In some cases, SOPs specific to a local crop are maintained at a regional site. SOPs must also be available at the site at which the raw data are archived. 

The pore size of porous titania can be up to 2000 A. Titania is used for the purification of proteins and as a support for bound enzymes. The purification of /1-lactoglobulin from cheese whey, of protease from pineapple, /5-lactamase, and amylase can be achieved with titania. The latter two purifications are impossible on alumina. Titania is also used as a support in peptide synthesis. The separation of plasmid DNA is shown in Figure 3.24. 

In total, 12,264 samples were collected and analyzed for pesticide residues in the 2001 PDP (USDA, 2003). Specific fruits and vegetables analyzed in the 2001 PDP included apples, bananas, broccoli, carrots, celery, cherries, grapes, green beans, lettuce, mushrooms, nectarines, oranges, peaches, pineapples, potatoes, canned sweet corn, canned sweet peas, and canned tomato paste. Fruits and vegetable samples were taken most commonly (9903 samples), followed by beef (911 samples), enriched milled rice (689 samples), poultry (464... 

Oxalic acid occurs in high concentrations in pineapple and rhubarb, among other plants, and is responsible for the sharpness of the fresh fruits. Ingestion of too much oxalic acid can cause gastroenteritis, commonly recognized as a stomach ache. A salt of oxalic acid, calcium oxalate, is the stuff of kidney stones. 

We can do more. We can make a simple structural change to this ester and obtain a new fragrance. If we replace the methyl group by an ethyl group, to get ethyl butyrate and the smell of pineapple ... 

C6Hg03, Mr 128.13, is a constituent of pineapple and strawberry aroma and is also found in other foods. It forms colorless crystals (mp 77-79 °C) with a relatively weak, nonspecific odor. Dilute solutions develop a pineapple, strawberry-like odor. It can be prepared by cyclization of hexane-2,5-diol-3,4-dione in the presence of an acidic catalyst [186]. The dione is the ozonization product of 2,5-hexynediol, which is obtained by ethynylation of acetaldehyde.
