(A) 1) at First a Pair of Each 10G. of Sample Was Extracted with Ether by the Soxhlet's Apparatus for a Week
52 [vol. 6, THE DISTRIBUTION OF PHOSPHORUS IN COW'S MILK AND THE SCHEME FOR THE SEPARATION OF PHOSPHATIDES By Rinjiro SASAKI (From the Institute of Agricultural Chemistry, College of Agriculture, Tokyo Imperial University) (Received 9th September 1930) A. The Distribution of Phosphorus in Cow's milk In order to extract the phosphatides, it is necessary first to determine the distribution of phosphorus in cow's milk. Liquid milk can not be extracted with ether or with other organic solvents owing to its large content of water. The substance applied in this experiment is the milk powder, dried by the Buflovak drum drier below 70•Ž. Its content of moisture is 4.498%, deter mined by the method of drying in the air bath of 105•Ž. The content of total phosphorus was determined(5) in the ash of sample which was burned with a little of fusing mixture. In 100g. of milk powder In 100g. of dry matter Total phosphorus 0.745g. 0.781g. The amounts of phosphorus, which are soluble in the various organic sol vents, were determined by extracting with three solvents in the following orders. (A) Ether-Acetone-Alcohol (B) Acetone-Ether-Alcohol (C) Alcohol-Ether-Acetone Experiment (A) 1) At first a pair of each 10g. of sample was extracted with ether by the Soxhlet's apparatus for a week. After the extraction had been comp leted, the extract was freed from ether and weighed. In 100g.of milkpowder In 100g.of dry matter Total ether matters soluble 3.609g. 3.779g. 2) The above extract was dissolved in a very little of ether. -

Particularly Hazardous Substances
Particularly Hazardous Substances In its Laboratory Standard, OSHA requires the establishment of additional protections for persons working with "Particularly Hazardous Substances" (PHS). OSHA defines these materials as "select" carcinogens, reproductive toxins and acutely toxic materials. Should you wish to add: explosive, violently reactive, pyrophoric and water-reactve materials to this category, the information is included. Carbon nanotubes have also been added due to their suspected carcinogenic properties. This table is designed to assist the laboratory in the identification of PHS, although it is not definitively conclusive or entirely comprehensive. *Notes on the proper use of this table appear on page 12. 1 6 5 2 3 4 Substance CAS National Toxicity National Program Carcinogen Toxin Acute Regulated OSHA Carcinogen Group IARC Carcinogen Toxin Reproductive Violently Reactive/ Explosive/Peroxide Forming/Pyrophoric A-a-C(2-Amino-9H-pyrido[2,3,b]indole) 2648-68-5 2B Acetal 105-57-7 yes Acetaldehyde 75-07-0 NTP AT 2B Acrolein (2-Propenal) 107-02-8 AT Acetamide 126850-14-4 2B 2-Acetylaminofluorene 53-96-3 NTP ORC Acrylamide 79-06-6 NTP 2B Acrylyl Chloride 814-68-6 AT Acrylonitrile 107-13-1 NTP ORC 2B Adriamycin 23214-92-8 NTP 2A Aflatoxins 1402-68-2 NTP 1 Allylamine 107-11-9 AT Alkylaluminums varies AT Allyl Chloride 107-05-1 AT ortho-Aminoazotoluene 97-56-3 NTP 2B para-aminoazobenzene 60-09-3 2B 4-Aminobiphenyl 92-67-1 NTP ORC 1 1-Amino-2-Methylanthraquinone 82-28-0 NTP (2-Amino-6-methyldipyrido[1,2-a:3’,2’-d]imidazole) 67730-11-4 2B -
Ghs Reference Materials Health Hazard Criteria
APPENDIX F: GHS REFERENCE MATERIALS This appendix provides both an overview of GHS highly toxic hazard classification. A listing of Particularly Hazardous Substances that Carnegie Mellon University has published with their Chemical Hygiene plan is also provided as general reference. The list is useful cross check with GHS listings to determine which materials require prior approval for use BUT NO LIST IS COMPLETE you must check the SDS for possible additional chemicals rated as highly toxic. This appendix also provides the GHS (global harmonization system) for chemical hazard classification under the Hazard Communication Standard for highly toxic materials. This section provides overall information about categories under the classification of acute toxicity, mutagens’, reproductive and carcinogen hazards. When chemicals are rated on the GHS – Safety Data Sheet (SDS) as the following hazards then the PRIOR APPROVAL PROCESS WITH CHEMICAL HYGIENE OFFICER/COMMITTEE must be used: Acute toxicity category 1 and 2, Germ cell mutagenicity as a category 1A Substances known to induce heritable mutations in germ cells of humans and Category 1B: Substances which should be regarded as if they induce heritable mutations in the germ cells of humans, Reproductive Hazard as a category 1: Known or presumed human reproductive toxicants and Category 2; suspected human reproductive toxicant. Carcinogen as a Category 1 (includes 1A and 1B): Known or presumed human carcinogens, Category 2: Suspected human carcinogens. The Campus Chemical Hygiene Committee (Officer) must conduct a prior approval process. Appendix C Chemical Prior Approval Form on procedure for conducing prior approval. The following is from OSHA standard on the chemicals classifications that PCC Laboratory instructional operations shall use for defining the prior approval hazards. -

They also contain some non-nutrient mixtures which exert beneficial effects to the human body known as phytochemicals. Phytochemicals are the chemical compounds that are synthesised by the plant cells to fight any kind of stress conditions. Isothiocyanates (ITCs) are the secondary metabolites produced by the plant from the enzymatic hydrolysis of glucosinolates by myrosinase during the plant tissue injury. They are present in Cruciferous vegetables, such as cabbage, broccoli and kale and are sulphur rich compounds. Isothiocyanates have been found to play an important role for the plant against microbial and pest infections. ITCs have been found to have beneficial activities like antibacterial, antifungal, bioherbicidal, and antioxidant, biopesticidal, anticarcinogenic and antimutagenic. Due to these activities they are having applications in food preservation like fruit juices and as an additive in Mayonnaise. Their recent application has been in the food packing’s and in MAP. The present review gives the insight of these phytochemicals, their physiological functions and food applications Keywords : Isothiocyanates, glucosionolate, sources, biocidal, food applications. Introduction in the vapour phase (Isshiki et al., 1992) and due to this characteristic property, it has been able to be used as food Isothiocyanates are the type of phytochemicals that are preservative in a number of foods stuffs.
