Supporting document 1 Risk and Technical Assessment Report – Application A1103 Citric & Lactic Acids as Food Additives in Beer and related products Executive Summary FSANZ received an Application from DB Breweries Limited seeking to amend Standard 1.3.1 – Food Additives of the Australia New Zealand Food Standards Code (the Code) to permit the addition of citric and lactic acids as food additives in beer. Within Standard 1.3.1, this permission would apply to the food category 14.2.1 - Beer and related products. Citric and lactic acids are currently permitted as food additives in a large range of foods at levels consistent with Good Manufacturing Practice (GMP). For the proposed use of citric and lactic acids in beer and related products, this Application also requests GMP permission. The food technology assessment concluded that certain types of beers exhibit improved flavour profiles due to pH reduction achieved by the addition of citric and lactic acids. Maximum levels of addition are expected to be approximately 3 g per litre of beer (total of citric acid plus lactic acid). Citric acid and lactic acid are substances of very low toxicity. Citric acid occurs in many foods, with levels of approximately 10 and 50 g/L in orange juice and lemon juice, respectively. Lactic acid levels are highest in foods produced by fermentation, with levels of approximately 10 g/kg reported for cheese and yogurt. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) concluded that establishment of an Acceptable Daily Intake (ADI) expressed in numerical terms was unnecessary for either substance. -

Juices from Non-Typical Edible Fruits As Health-Promoting Acidity Regulators for Food Industry
Post-print of: Koss-Mikołajczyk I., Kusznierewicz B., Namieśnik J., Bartoszek-Pączkowska A.: Juices from non-typical edible fruits as health-promoting acidity regulators for food industry. LWT-FOOD SCIENCE AND TECHNOLOGY. Vol. 64, iss. 2 (2015), p. 845-852. DOI: 10.1016/j.lwt.2015.06.072 Juices from non-typical edible fruits as health-promoting acidity regulators for food industry Izabela Koss-Mikołajczyk a, Barbara Kusznierewicz a, Jacek Namiesnik b, Agnieszka Bartoszek a a Department of Food Chemistry, Technology and Biotechnology, Gdansk University of Technology, Gdansk, Poland b Department of Analytical Chemistry, Gdansk University of Technology, Gdansk, Poland abstract The study verifies the possibility of application of juices from selected fruits characterized by the high antioxidant potential as natural acidity regulators with improved nutritional properties. The tested non-typical fruits included mirabelle plum, sea buckthorn and blue-berried honeysuckle. Beetroot juice whose pH is about 6.0 served as a model food product. Potentiometric titration was used to compare the efficacy of tested juices as acidity regulators with that of citric þ acid, a widely applied acidity regulator. The antioxidant activity of tested mixtures of juices was determined by spectrophotometric ABTS (2,2-azinobis- (ethyl-2,3-dihydrobenzothiazoline-6-sulphonic acid) diammonium salt) test and their cytotoxic activity was assessed by MTT (thiazolyl blue tetrazolium bromide) test. The potentiometric titration revealed that the efficacy of the juices proposed as acidity regulators matched that of citric acid. Among the mixtures of beetroot juice and titrants studied, the addition of blue-berried honeysuckle juice ensured the highest antioxidant activity, followed by sea buckthorn and mirabelle plum juices. -

A Cinnamon and Benzoate Free Diet for Orofacial Granulomatosis
May 2015 A cinnamon and benzoate free diet for orofacial granulomatosis: Orofacial granulomatosis (OFG) is a condition which affects mainly the mouth and lips. Swelling and redness are the most common symptoms but other symptoms such as mouth ulcers and cracked lips can occur too. The cause is not known but a cinnamon and benzoate free diet helps 70% of people with OFG. Avoiding foods which contain cinnamon and benzoates may help your oral symptoms. You should try and follow this diet for 12 weeks and monitor any improvements in your symptoms diary. Keep to fresh or home cooked food where possible. If you are unsure whether a food or drink may contain cinnamon or benzoate, it is best to avoid it. It is important that you read the labels of any manufactured or prepared foods you consume. 1 Page 2 of 13 Cinnamon Cinnamon is a natural substance, which because it is used in very small quantities does not always have to be stated on food labels. Look for the word spices, spice extracts, ground cinnamon, mixed spice, cinnamon oil, cinnamal or cinnamic aldehyde on food labels. Benzoates Most benzoates are added to food and drinks as a preservative. They are commonly added to fizzy drinks and processed foods. High levels of benzoates may also occur naturally in certain foods. Benzoates includes any of these preservatives: E210 or Benzoic acid E211 or Sodium benzoate E212 or Potassium benzoate E213 or Calcium benzoate E214 or Ethyl 4-hydroxybenzoate or Ethyl para-hydroxybenzoate E215 or Ethyl 4-hydroxybenzoate, sodium salt or sodium ethyl para-hydroxybenzoate *E216 or Propyl 4-hydroxybenzoate or Propyl para-hydroxybenzoate *E217 or Propyl 4-hydroxybenzoate, sodium salt or sodium para-hydroxybenzoate E218 or Methyl 4-hydroxybenzoate or Methyl para-hydroxybenzoate E219 or Methyl 4-hydroxybenzoate, sodium salt or sodium methyl-hydroxybenzoate *banned in foods produced within the European Union but may be found in imported products. -
Berry and Fruit Juices As Potential Untraditional Acidity Regulators in Mashing
FOODBALT 2014 BERRY AND FRUIT JUICES AS POTENTIAL UNTRADITIONAL ACIDITY REGULATORS IN MASHING Ingmars Cinkmanis, Sanita Vucane, Ilze Cakste Department of Chemistry, Faculty of Food Technology, Latvia University of Agriculture, Liela street 2, Jelgava, Latvia, e-mail: [email protected] Abstract Acids traditionally used for acidification of mash (lactic acid, phosphorus acid) provide optimal medium pH, however, it is theoretically possible to choose such agents that would complete several tasks, ensuring the regulation of pH. Berry and fruit juices (cranberry, black currant, red currant, quince, apple and lemon) containing different organic acids, such as citric acid, malic acid, tartaric acid and fumaric acid, have similar properties, although they can not only acidify mash but also increase the content of extract substances in wort. In berries and fruits juices titratable acidity and pH was measured potentiometrically using pH meter. The highest titratable acidity of berry and fruit juices was in lemon (5.71 mmol L-1) and quinic juice (5.80 mmol L-1). Lemon juice has a lower pH 2.40 and apple juice has the highest pH 4.82. Results of the analysis of mash pH changes showed, that it is possible to reduce pH replacing traditional acidification regulators (lactic acid, phosphoric acid) with berry and fruit juices. The pH was practically in all the mashing stages in the limits of 5.14±0.02 up to 5.19±0.02. The content of wort extract was analyzed using beer analysing system – Anton Paar „Alcolaizer” analysis. Using HPLC the Carbohydrates like glucose and maltose in wort were detected and quantified. -
E Number from Wikipedia, the Free Encyclopedia
E number From Wikipedia, the free encyclopedia E numbers are codes for substances which can be used as food additives for use within the European Union[1] and Switzerland (the "E" stands for "Europe").[2] They are commonly found on food labels throughout the European Union.[3] Safety assessment and approval are the responsibility of the European Food Safety Authority.[4] Having a single unified list for food additives was first agreed upon in 1962 with colours. In 1964, the directives for preservatives were added, 1970 for antioxidants and 1974 for the emulsifiers, stabilisers, thickeners and gelling agents.[5] Contents A solution of E101 riboflavin (also 1 Numbering scheme known as Vitamin B2) 2 Colloquial use 3 Classification by numeric range 4 Full list 4.1 E100–E199 (colours) 4.2 E200–E299 (preservatives) 4.3 E300–E399 (antioxidants, acidity regulators) 4.4 E400–E499 (thickeners, stabilizers, emulsifiers) 4.5 E500–E599 (acidity regulators, anti-caking Crystals of E621 Monosodium glutamate, a flavour enhancer agents) 4.6 E600–E699 (flavour enhancers) 4.7 E700–E799 (antibiotics) 4.8 E900–E999 (glazing agents and sweeteners) 4.9 E1000–E1599 (additional chemicals) 5 See also 6 Notes 7 External links Numbering scheme The numbering scheme follows that of the International Numbering System (INS) as determined by the Codex Alimentarius committee,[6] though only a subset of the INS additives are approved for use in the European Union as food additives. E numbers are also encountered on food labelling in other jurisdictions, including the Cooperation Council for the Arab States of the Gulf, Australia, New Zealand[7] and Israel. -
