KOSHER certificates are usually divided into the following classifications
1. Kosher Pareve (Kosher neutral products)
Kosher Pareve products contain no meat or dairy ingredients. Therefore, in addition to Jewish consumers who must use Kosher products for religious reasons, Kosher Pareve products are also the best choice for people with lactose intolerance (lactose allergy). Pareve foods can be eaten together with either Kosher-Meat or Kosher-Dairy products respectively. Meat and Dairy are discussed below.
2. Kosher Passover (Kosher Passover products)
Kosher Passover means that the certified products comply with Passover regulations. According to the Jewish Old Testament, Passover is also called the Feast of Unleavened Bread. During Passover, no fermented ingredients may be eaten, and all leavened things must be removed. Passover lasts seven or eight days. It commemorates the Creator's guidance of the Jewish prophet Moses in leading the Jewish people out of Egypt, ending more than 400 years of exile. From its literal meaning you can also understand Passover as: PASSOVER = PASS + OVER = to pass through + to end = 'crossing over' (that is, having crossed over the calamity, arriving at the promised land of Canaan that the Creator promised, entering a brand-new beginning, severing the connection with the past). Because Kosher Passover products are certified products specifically for Passover, that is, containing no leavened ingredients, not eating food produced from barley, rye, oats, wheat and spelt, nor containing corn, soy oil, corn syrup, dextrose or any legumes. Jews in European countries also do not eat grain-like foods such as corn, rice, legumes and sesame. Therefore, Kosher Passover products will not contain any gluten ingredients. Thus, for Kosher Passover products, in addition to Jewish consumers who must use Kosher Passover products due to Passover religious customs, they are also favored by those with gluten allergies. According to statistics, the proportion of gluten-allergic people in Europe is 4%, and gluten allergy is a lifelong disease; patients must strictly limit their gluten intake for life.
3. Kosher Meat (Kosher products containing meat ingredients)
Kosher Meat means that the certified Kosher products contain meat ingredients (precise to the smallest trace level). According to the Jewish Old Testament, meat may not be eaten together with dairy (if meat has been eaten, the meat must be digested in the stomach for 8 hours, i.e., fully broken down, before dairy is eaten, and vice versa).
4. Kosher Dairy (Kosher products containing dairy ingredients)
Kosher Dairy means that the certified Kosher products contain dairy ingredients (precise to the smallest trace level). According to the Jewish Old Testament, meat may not be eaten together with dairy (if meat has been eaten, the meat must be digested in the stomach for 8 hours, i.e., fully broken down, before dairy is eaten, and vice versa).
5. Glatt Kosher
Glatt Kosher - Glatt is Yiddish, meaning smooth, and refers to beef from cattle slaughtered according to Jewish dietary customs whose lungs have no lesions. Jewish consumers very strictly accept only high-standard Kosher, requiring all Kosher meat products to be 'Glatt.' Glatt is often mistakenly used to distinguish foods, between those with high-standard Kosher supervision and those with more lenient Kosher certification.
