The Measuring Development Plan (2013- 2020) issued by State Council points out that Food safety, clinical laboratory, biological, environmental protection, material science become the focus of research and development of reference materials. Now, the reference materials of gas permeability, water vapor permeability and oxygen permeability produced by GBPI win the affirmation of Grade Secondary Reference Materials. GBPI becomes the first development organization of the reference materials of film permeability. These reference materials are mainly applied to the calibration and inspection of the gas permeability, water vapor permeability and oxygen permeability of packaging of food and drug. Reference Materials plays a very important role in packaging testing.

Mace Botanical: Myristica fragrans Family: N.O. Myristicaceae Hindi Name: Mace - Javitri General Description: Nutmeg, spice consisting of the seed of the Myristica fragrans, a tropical, dioecious evergreen tree native to the Moluccas or Spice Islands of Indonesia. Geographical Sources The nutmeg tree, Myristica fragrans, is indigenous to the Moluccas in Indonesia but has been successfully grown in other Asian countries and in the Caribbean, namely Grenada. Banda Islands, Malayan Archipelago, Molucca Islands, and cultivated in Sumatra, French Guiana Composition -> Nutmeg and mace contain 7 to 14 percent essential oil, the principal components of which are pinene, camphene, and dipentene. Nutmeg on expression yields about 24 to 30 percent fixed oil called nutmeg butter, or oil of mace. Dried kernel of the seed. Varieties -> Whole nutmegs are grouped under three broad quality classifications: 1. Sound: nutmegs which are mainly used for grinding and to a lesser extent for oleoresin extraction. High quality or sound whole nutmegs are traded in grades which refer to their size in numbers of nutmegs per pound: 80s, 110s and 130s (110 to 287 nuts per kg), or 'ABCD' which is an assortment of various sizes. 2. Substandard: nutmegs which are used for grinding, oleoresin extraction and essential oil distillation. Substandard nutmegs are traded as 'sound, shrivelled' which in general have a higher volatile oil content than mature sound nutmegs and are used for grinding, oleoresin extraction and oil distillation; and 'BWP' (broken, wormy and punky) which are mainly used for grinding as volatile oil content generally does not exceed 8%. 3. Distilling: poor quality nutmegs used for essential oil distillation.Distilling grades of nutmegs are of poorer quality: 'BIA' or 'ETEZ' with a volatile oil content of 8% to 10%; and 'BSL' or 'AZWI' which has less shell material and a volatile oil content of 12% to 13%. Method of Processing -> When fully mature it splits in two, exposing a crimson-coloured aril, the mace, surrounding a single shiny, brown seed, the nutmeg. The pulp of the fruit may be eaten locally. After collection, the aril-enveloped nutmegs are conveyed to curing areas where the mace is removed, flattened out, and dried. The nutmegs are dried gradually in the sun and turned twice daily over a period of six to eight weeks. During this time the nutmeg shrinks away from its hard seed coat until the kernels rattle in their shells when shaken. The shell is then broken with a wooden truncheon and the nutmegs are picked out. Dried nutmegs are grayish-brown ovals with furrowed surfaces. Large ones may be about 1.2 inches long and 0.8 inch in diameter. Taste and Aroma: Nutmeg has a characteristic, pleasant fragrance and slightly warm taste
