Juices, lead levels

From these data it is clear that the problems reported earlier by several research scientists on this type of processed foods have not been solved in Mexico. Also, from these recent data it is clear that the worst problems regarding lead content are to be found in chipotle peppers, peaches in syrup and some brands of pineapples in syrup. Fruit juices and tomato products that have also been reported to have high lead levels were not included in this study. 

In response to extremely high lead levels found in some imported fruit juices, the FDA has begun the process to prohibit the use of lead solder in domestic or imported food cans. Until this prohibition is in effect, the agency has set emergency limits on how much lead is permitted in imported canned goods. Stricter limits were set for fruit juice because it is more likely that a young child would consume large quantities of fruit juice on a daily basis than other foods. 

We have seen figures and tables here showing that the lead level dropped in evaporated milk from 0.5 ppm to less than 0.1, for canned fruit juices from 0.3 ppm to about 0.014 ppm, and finally, for canned infant formula from 0.1 ppm to 0.02 ppm. As children absorb substantially more lead in the early phase of childhood than adults, the US Food and Drug Administration has made a special recommendation for infants and children, to which I referred already above The lead intake from all sources should be less than 100 ig per day for children up to 6 months of age, and should be less than 150 pg per day for children aged between 6 months and 2 years. 

Lead has been found in baby food, especially baby food with carrots, peaches, pears, and sweet potatoes (Dearen 2013). This particular issue involves a lawsuit filed by an environmental group that is demanding that contaminated baby food must carry a label for California s Proposition 65. Grape juice and fruit cocktail have also been known to have detectable levels of lead (Bolokhova 2013). The sources of lead appear to be contaminated soil and older processing equipment. Some Indian spices and cultural powders have been found to have lead levels that resulted in elevated blood lead levels in children (Gurgel 2010). 

Amylase enters the blood largely via the lymphatics. An increase in hydrostatic pressure in the pancreatic ducts leads to a fairly prompt rise in the amylase concentration of the blood. Neither an increase in volume flow of pancreatic juice nor stimulation of pancreatic enzyme production will cause an increase in senm enzyme concentration. Elevation of intraductal pressure is the important determinant. Stimulation of flow in the face of obstruction can, however, augment the entry of amylase into the blood, as can disruption of acinar cells and ducts. A functional pancreas must be present for the serum amylase to rise. Serum amylase determination is indicated in acute pancreatitis in patients with acute abdominal pain where the clinical findings are not typical of other diseases such as appendicitis, cholecystitis, peptic ulcer, vascular disease or intestinal obstruction. In acute pancreatitis, the serum amylase starts to rise within a few hours simultaneously with the onset of symptoms and remains elevated for 2 to 3 days after which it returns to normal. The peak level is reached within 24 hours. Absence of increase in serum amylase in first 24 hours after the onset of symptoms is evidence against a diagnosis of acute pancreatitis (76).

Measurement of Arabinan. Excess quantities of arabinan in fruit juice can lead (after prolonged storage) to hazy fruit-juice concentrates. This problem can be resolved by ensuring that the pectinase preparation employed contains adequate levels of endo-arabinanase to hydrolyse the amounts of debranched arabinan likely to be present. A limiting factor is that currently, there are no methods available for the measurement of arabinan in fruit juice or juice concentrates.

The concomitant intake of grapefruit juice increases the concentration of many drugs (e.g., testosterone, sildenafil) in humans. Such actions appear to be mediated mainly by the suppression of the cytochrome P450 enzyme CYP3A4 in the small intestine. The resultant diminished first-pass metabolism and increased bioavailability can lead to increased drug levels in the blood. Because sildenafil is metabolized by CYP3A and to a...

Within the Codex system, the contaminants considered in this section are mainly dealt with by the Codex Committee on Food Additives and Contaminants (CCFAC), which is hosted by the Netherlands. Many of the Member States of the European Union are very active in CCFAC. For example, Denmark and the Netherlands have been instrumental in developing the Codex General Standard on Contaminants and Toxins and draft limits for lead in various foods. Sweden has developed a proposal for a limit for ochratoxin A in cereals and cereal products and France has proposed a maximum level for patulin in apple juice.

Contrary to expectations that fungal diseases would lead to elevated levels of PR proteins in berries, Marchal et al. (1998) observed that juice from berries infected by B. cinerea showed reduced protein levels, and suggested that proteolytic enzymes from B. cinerea were responsible for this. Secretion of proteases by B. cinerea has been observed in culture media and on fruits such as apple (Zalewska-Sobczak et al. 1981) and tomato (Brown and Adikaram 1983). Girbau et al. (2004) also examined the impact of infection of grapes with B. cinerea in the vineyard and showed that infection resulted in marked decreases in the levels of PR proteins in...
