Owing to the relatively cheap nature of white cotton thread and the abundant nature of cheap, indigo -dyed blue cloth in historical Japan, sashiko has a distinctive ...
A fish fillet processor processes fish into a fillet. Fish processing starts from the time the fish is caught. Popular species processed include cod, hake, haddock, tuna, herring, mackerel, salmon and pollock . Commercial fish processing is a global practice. Processing varies regionally in productivity, type of operation, yield and regulation.
A medieval view of fish processing, by Peter Brueghel the Elder (1556). There is evidence humans have been processing fish since the early Holocene. For example, fishbones (c. 8140–7550 BP, uncalibrated) at Atlit-Yam, a submerged Neolithic site off Israel, have been analysed. What emerged was a picture of "a pile of fish gutted and processed ...
Fish hydrolysate, in its simplest form, is ground up fish transformed into a liquid phase, where the cleavage of molecular bonds occurs through various biological processes. Raw material choice; either whole fish or by-products, depends on the commercial sources of the fish. In some cases, the fillet portions are removed for human consumption ...
Aquatic feeding mechanisms. Grouper capture their prey by sucking them into their mouths. Aquatic feeding mechanisms face a special difficulty as compared to feeding on land, because the density of water is about the same as that of the prey, so the prey tends to be pushed away when the mouth is closed. This problem was first identified by ...
Pattern (casting) The top and bottom halves of a sand casting mould showing the cavity prepared by patterns. Cores to accommodate holes can be seen in the bottom half of the mould, which is called the drag. The top half of the mould is called the cope. In casting, a pattern is a replica of the object to be cast, used to form the sand mould ...

Products commonly frozen with IQF technologies are typically smaller pieces of food, and can include berries, fruits and vegetables both diced or sliced ...
Recirculating aquaculture systems at the Virginia Tech Department of Food Science and Technology. Recirculating aquaculture systems (RAS) are used in home aquaria and for fish production where water exchange is limited and the use of biofiltration is required to reduce ammonia toxicity. [1] Other types of filtration and environmental control ...
