of things allow me to enlighten you about sushi fish production.<\/p>\n<p>The Yellowfin Tuna (Latin name \u2013\u00a0<i>Thunnus Albacares<\/i>), a popular sushi delicacy, is mainly caught in South East Asia and is sold predominantly from Chinese fishing boats.\u00a0\u00a0They employ long-line fishing in contrast to a net method.\u00a0\u00a0When tuna is not designated for canning, this method is used in order to minimize bruising.\u00a0\u00a0\u00a0Packed in chipped ice flakes, tuna is sold on auction to the highest bidder.\u00a0\u00a0Severe shortages of this over-fished species and huge demand from the Japanese market drive the price up considerably.<\/p>\n<p>These factors of supply and demand contribute to the perpetration of industry fraud.\u00a0\u00a0There have been recorded cases of other fish being substituted and sold as tuna.\u00a0\u00a0There have been instances where the accepted method of \u2018<i>pas kaskeses<\/i>\u2019, leaving a skin patch on the deboned and skinned fillet, has been adulterated.<\/p>\n<p>These skilled perpetrators have cleverly developed a method of sticking scaled skin patches onto the cuts.\u00a0\u00a0The enzymes in the meat\/skin, and the subsequent freezing of the cuts, cause the skin patch to appear to have been grown on the fish.\u00a0\u00a0In order to beat these scallywags at their own game, we check the tuna when it arrives at the factory &#8211; whole, unskinned, and fresh.\u00a0\u00a0We check that there is no other fish accessible in the plant at the time of kosher processing, and we confirm that what is packaged is certified kosher tuna.<\/p>\n<p>As an imported product, the US FDA is extremely strict, testing that there are no nasty germs, histamines or parasites in this raw product.\u00a0\u00a0Did you know that after the tuna has been skinned and cut it is particularly prone to infection?\u00a0\u00a0Therefore, to help the product pass customs inspection with a clean bill of health, the manufacturer will\u00a0soak the fish in an antibacterial preservative solution which contains chemicals and disinfectants.\u00a0\u00a0The mixture (a powder mixed with water) also may act as a firming agent and flavour enhancer. The tuna is immersed in these solutions for a prescribed amount of time to ensure that the meat of the fish is penetrated sufficiently to do its job.\u00a0\u00a0We make no assumptions!\u00a0\u00a0We carefully check that these solutions are reliably kosher certified, in spite of the fact that the certified product is more costly.<\/p>\n<p>Another cost-saving method of germ prevention is Ethanol.\u00a0\u00a0Ethanol can be made from a variety of source materials that will be converted into alcohol.\u00a0\u00a0In South Africa, the manufacturer will use the cheapest starter material available.\u00a0\u00a0The raw product used to make alcohol is seasonal, and the cheapest one is the one that is most plentiful at the time.\u00a0\u00a0South Africa enjoys a fruitful grape season; that which falls off the vine and not turned into wine is used to make Ethyl Alcohol.\u00a0Alternatively, alcohol from South Africa can also be made from sugar.<\/p>\n<p>Often, there is a foregone conclusion that raw fish is automatically\u00a0Kosher\u00a0for Passover.\u00a0\u00a0Similarly, it is assumed that sugar-based ethanol is Kosher for Passover.\u00a0\u00a0This may not be the case.\u00a0\u00a0To process sugar cane into sugar, enzymes are used to break down the sugar cane cells so that there is greater yield for the alcohol manufacturer.\u00a0\u00a0This amylase enzyme may be\u00a0<i>kitniyos<\/i>,<i>\u00a0<\/i>or even<i>chometz<\/i>!<\/p>\n<p>When certifying a Kosher for Passover (KFP) sugar production, we ensure that the enzymes used are Kosher for Passover and that the enzyme starter materials are strictly Kosher for Passover.\u00a0\u00a0In the case of Passover certified tuna, we see that the sugar-derived alcohol has Kosher for Passover enzymes in it when it is produced and that the ethanol is certified as KFP.\u00a0\u00a0Once all Passover conditions are met, we can then also certify the tuna as\u00a0Kosher\u00a0\u00a0for\u00a0Passover.<\/p>\n<p>Another issue that we often confront when processing kosher fish is cross contamination with\u00a0<i>treif<\/i>fish.\u00a0\u00a0Furthermore, do you know that the nice smoked red color on your tuna sashimi (with a skin-patch) may be due to a red dye bath of carmine (a brilliant color stable red derived from crushed beetles)?\u00a0\u00a0We make sure that all colorants are reliably kosher certified.<\/p>\n<p>When we supervise fish production in a common facility, we segregate production and\u00a0<i>kasher\u00a0<\/i>the factory and equipment to ensure that the plant is dedicated to kosher fish production.\u00a0\u00a0We confirm that nothing is produced on\u00a0<i>Shabbos.\u00a0\u00a0<\/i>When\u00a0<i>Bishul<\/i>\u00a0<i>Yisroel<\/i>\u00a0is necessary, we light the smokers and make sure that there is no cross contamination with\u00a0<i>treif<\/i>\u00a0fish in the smokers.<\/p>\n<p>Clearly, there are many operators who will happily cut corners by spinning you a line.\u00a0\u00a0Don\u2019t fall hook, line and sinker for the scam.\u00a0\u00a0Buy only kosher certified products!<\/p>\n<p><b><span style=\"text-decoration: underline;\">From the Front Lines 2:\u00a0\u00a0Creating Rice Vinegar<\/span><\/b><br \/>\nRabbi Amos Benjamin, STAR-K\u00a0<i>Kashrus<\/i>\u00a0Administrator<\/p>\n<p>One of sushi\u2019s basic ingredients is rice vinegar.\u00a0\u00a0Rice vinegar serves two purposes &#8211; it imparts flavor, and it serves as a preservative so that the sushi will not spoil.\u00a0\u00a0Unlike grain vinegar or apple cider vinegar that uses grain alcohol in the process, rice vinegar uses alcohol from rice wine popularly known as\u00a0<i>sake<\/i>.\u00a0\u00a0In order to convert the rice into alcohol, a mold known as\u00a0<i>koji\u00a0<\/i>\u00a0is\u00a0used in the fermentation process.\u00a0\u00a0Are there any\u00a0<i>kashrus<\/i>\u00a0concerns in the manufacturing of the koji mold, a basic component in the production of rice vinegar?<\/p>\n<p>Amos Benjamin, STAR-K Director of Far East operations, offers this first-hand report of a koji<i><\/i>production in Japan.<\/p>\n<p>The first stage of the koji process is to mix raw rice and cold water.\u00a0\u00a0The rice is then transferred to a pressure cooker, where it is \u2018par cooked\u2019.\u00a0\u00a0The rice is barely edible.\u00a0\u00a0It still hasa low\u00a0moisture content and is nowhere near being fully cooked, so there would be no issues of<i>bishul akum<\/i>.\u00a0\u00a0After cooking, the rice is ready to be converted into the koji mold.<\/p>\n<p>The rice is seeded with koji extract, which comes from a previously grown koji mold.\u00a0\u00a0The culture uses only rice,\u00a0<i>Aspergillus Oryzae<\/i>\u00a0(a fungus which is inoculated into the rice), and water.\u00a0\u00a0The koji extract propagates the \u2018par cooked\u2019 rice to create more koji.\u00a0\u00a0The rice is seeded with the koji extract, transferred to wooden trays and left to culture for five to seven days at a temperature of 45<sup>o<\/sup>C.\u00a0\u00a0Now the koji mold has spread and is ready for the next step.<\/p>\n<p>The molded rice is dried for two days with warm air.\u00a0\u00a0The completed product is known as<i>tanakoji<\/i>.\u00a0\u00a0In order to produce the other finished product, koji-kin, the molded rice is passed through a sifter to separate the mold spore from the rice.\u00a0\u00a0The spore powder is blended with potato starch and is packed and ready to be used to convert the rice into rice wine, also known as\u00a0<i>sake<\/i>, which provides the basis for rice vinegar.<\/p>\n<p>In a rice vinegar fermentation process, the rice\u2019s natural starch is converted into a sugar, similar to the malting process of barley; this occurs when the rice is mixed with water.\u00a0\u00a0The koji is then added to the \u2018malted\u2019 rice syrup along with other enzymes.\u00a0\u00a0The rice fermentation process converts the sugars into rice alcohol, known as sake.<\/p>\n<p>The sake alcohol is then separated from the solid rice.\u00a0\u00a0The liquid sake is then ready for a second fermentation process, whereby bacteria converts the alcohol into acetic acid, concentrated vinegar \u2013 in this case, rice vinegar.\u00a0\u00a0The concentrated vinegar is diluted with water to 4.3% acidity and is ready to be mixed with sushi rice and sold to the sushi bars.<\/p>\n<p><b><span style=\"text-decoration: underline;\">From the Front Lines 3:\u00a0\u00a0The Making\u00a0Of\u00a0Nori<\/span><\/b><\/p>\n<p><i>NO\u2022RI \/ n\u014dr\u0207\/\u00a0an edible\u00a0seaweed eaten either fresh or dried in sheets.<\/i><\/p>\n<p>Nori is not a vegetable;
