Case hardening is the result of a large amount of heat dehydrated production, which hardens the exterior of the fruit or vegetable, making it difficult to avoid moisture crumb. The food dried at a very high temperature, the outer surface will harden, preventing moisture from escaping through the center of the slice. The food shrinks when it ...
The Philippines' Bureau of Agriculture and Fisheries Product Standards (Filipino: Kawanihan ng mga Pamantayan sa Produktong Pansaka at Pampangisdaan, abbreviated as BAFS), is an agency of the Philippine government under the Department of Agriculture responsible for setting and implementing standards for fresh primary and secondary processed agricultural and fishery products.
Colt Peacemaker, showing discoloration from case-hardening. Case-hardening or carburization is the process of introducing carbon to the surface of a low-carbon iron, or more commonly a low-carbon steel object, in order to harden the surface. Iron which has a carbon content greater than ~0.02% is known as steel.
It was created on May 24, 1978, through Presidential Decree 1380 to spearhead the development of the country's postharvest industry. As a subsidiary of the National Grains Authority (NGA) in 1980, BPRE's powers and functions were expanded through LOI 1142 to include other agricultural commodities in line with the conversion of NGA to the ...
A few typical hardening agents include carbon monoxide gas (CO), sodium cyanide and barium carbonate, or hardwood charcoal. In gas carburizing, carbon is given off by propane or natural gas. In liquid carburizing, the carbon is derived from a molten salt composed mainly of sodium cyanide (NaCN) and barium chloride (BaCl 2). In pack carburizing ...
This also inversely affects the depth of the case; i.e., a high carbon steel will form a hard, but shallow case. [14] A similar process is the trademarked "Nu-Tride" process, also known incorrectly as the "Kolene" process (which is the company's name), includes a preheat and an intermediate quench cycle.
The National Food Authority was created by President Ferdinand Marcos through Presidential Decree No. 4 dated September 26, 1972, under the name National Grains Authority (NGA) with the mission of promoting the integrated growth and development of the grains industry covering rice, corn, feed grains and other grains like sorghum, mung beans, and peanuts.

Defects from uneven drying, resulting in the rupture of the wood tissue, such as checks (surface, end and internal), end splits, honey-combing and case hardening. Collapse, often shown as corrugation, or so-called washboarding of the wood surface, may also occur (Innes, 1996). Collapse is a defect that results from the physical flattening of ...
