Small fruit juice production

PM seems to occur in small amounts in the vegetative tissues of all higher and lower plants investigated. It is very abundant in the tomato fruit,60 orange flavedo and albedo,21 the tobacco plant,61 eggplant62 and alfalfa it usually occurs in the commercial fungal pectinase preparations that are manufactured for the clarification of fruit juices.25 In the natural products in which the enzyme is found, the major portion of it is usually strongly adsorbed on the water-insoluble cellular components of the tissue macerates.60 62 68... 

Two of the most important classes of chemical compounds are acids and bases. A small sampling of acids and bases found around the home demonstrates their importance in daily life. A few of these include fruit juice, aspirin, milk, ammonia, baking soda, vinegar, and soap. Beyond their presence in numerous household items, acids and bases are key ingredients in the chemical process industry. More sulfuric acid is produced than any other chemical in the United States with an annual production of 40 million tons. While the commercial applications of acids and bases illustrate their importance in everyday life, on a more fundamental level each one of us inherited our characteristics and genetic make-up through the acid DNA, deoxyribonucleic acid. 

Like all artificial sweeteners, aspartame has had some critics. When this substance breaks down in the body it forms aspartic acid, phenylalanine, and methanol. The first two compounds are naturally present in the body and pose no hazard to most people. However, about one person in 15,000 suffers from a disease called phenylketonuria, which makes an individual sensitive to excess phenylalanine. People with this condition must avoid aspartame. Also, the fact that methanol is a product of the breakdown of aspartame makes some people concerned, because methanol is a toxic substance. Nevertheless, studies have shown that the small amount of methanol produced from aspartame poses no risk. In fact, a glass of natural fruit juice contains as much methanol as is produced from typical use of aspartame. 

Yeast species commonly isolated from fruit juices were Rhodotorula rubra, Candida lambica, Candida sake, and K. apis, with C. lambica being the organism most frequently encountered in these products. Small numbers of Penicillium and Fusarium spp. were isolated from 20%, whereas Geotrichum spp. were present in 40% of the grapefruit juice samples tested. All other products contained no molds. The fact that these organisms were present in very low quantities indicated that they were random contaminants not able to grow in the refrigerated juice. 

Figure 4 shows a spinner head for glass fiber production. As shown in the figure, so many small holes are made in nickel-based alloy plate by the electron beam drilling. The hole diameter is about 0.6 nun, and the thickness is about 5 mm (furnished by Pacific Special Alloy Castings Co., Ltd.). Figure 5 is a liner strainer made of stainless steel which is used as a filter to remove foreign objects from fruit juice. The diameter is 0.25 nun. 

Low level NDC modification of PET has been used in Japan for Listerine Cool Mint mouthwash, a product of Warner-Lambert Japan. The PETN copolymer in these 80-mL to 700-mL bottles is used to extend shelf life by protection from UV exposure, as well as to prevent absorption of the active ingredients of the mouthwash into the bottle (30). Another commercial packaging application, relying on the UV barrier property of naphthalates, was Fujiya s Lemon Squash (34), packaged in a 1.5-L PETN copolymer bottle. A small amount of naphthalate was incorporated into the PET resin to protect the drink s natural fruit juices and added Vitamin C. 

Apple polyphenols are present in different parts of the fruit. A major source is the skin, which contains all the flavonols and anthocyanins in addition to an important amount of dihydrochalcones. ° Phenolic acids are present in the flesh whereas most of the dihydrochalcones are in the core and the seeds. This distribution in different parts of the fruit also affects polyphenol concentration of apple juice where only small amounts of quercetin glycosides and dihydrochalcones are present. However, polyphenol content is also affected by the technological procedure. The oxidative conditions and the clarification process during the production of clear apple juice reduces the phenolic content. In contrast, the anaerobic conditions and the lack of a clarification step during cloudy apple juice production prevents an important loss of polyphenols. ... 

A constituent of orange peel that is suspected of causing damage to blood vessels when large amounts are consumed. Orange peel is present in such food products as marmalade, fruit juices, and fruit drinks. However, it is not known whether many people are affected by the small amount of citral that is usually consumed. 

A rapid application of superheated steam which quickly distills off a small volume, 1% of the liquid being condensed. This flash distillate carries the volatile flavor constituents. Later, these flavors are added back to the concentrate. This process is employed in the production of concentrated fruit juices.
