  • Packaging of Dairy Products - II
    Paper no.: 12 Paper Title: Food Packaging Technology Module-19: Packaging of Dairy Products - II 19.1 Introduction In this module, we will discuss regarding the packaging of butter, ghee, cheese and milk powder. Butter and ghee contains a high percentage of fat, so they are very susceptible to spoilage. So packaging material used should be selected in such a way that it possesses good grease resistance, and barrier properties against oxygen and moisture. Cheese is fermented dairy product, having low pH and comparative higher moisture content while milk powder is dried product, containing very low moisture. 19.2 Butter It consists primarily of about 80% milk fat, 16% moisture and in table butter up to 3% common salt. Because of high moisture content butter is susceptible to mold growth and lypolytic rancidity 19.2.1 Characteristics of Butter 1. Due to high moisture content butter unlike solid fats is susceptible to mold growth. 2. Flavour and odour are easily absorbed by butter from its environment. 3. Deterioration of the butter may take place due to rancidity. 4. Butter has tendency to lose Moisture. 19.2.2 Requirement of Packaging: 1. Non toxic, not harmful to consumer’s health. 2. It should be grease/moisture proof. 3. Shall be barrier for Oxygen. 4. Low metallic content as metals favor oxidation of fat. 5. Shall not transmit light. 19.2.3 Packaging Material In India, butter is packed in bulk as well as in retail packages. For bulk packaging, there is no standard method, and generally polyethylene bags/parchment paper along with corrugated boxes are used.

Several sessions of the lab section consisted of him showing the class portions of online lectures about creativity (Elizabeth Gilbert’s TED video is certainly worth a look), talking to us about his own creative challenges – such as a course he took as a college student which required him to compose a new piece each week – and urging the class to discuss our own methods and difficulties.

  • PRESS RELEASE Paper and Plastic Sacks Provide Equivalent Shelf Life
    PRESS RELEASE 11th December 2019 Paper and plastic sacks provide equivalent shelf life Paris/Stockholm, 11th December 2019: A recent study found that paper sacks and form-fill- seal (FFS) polyethylene sacks provided equivalent protection for cement when stored for 18 months under the same conditions. The study was conducted by the Norwegian research organisation SINTEF on behalf of the European Paper Sack Research Group (ESG), a collaboration between CEPI Eurokraft and EUROSAC. “Since cement hardens when reacting with water, perfect product protection of the packaging is vital when storing cement for a longer period of time in order to conserve its quality and properties,” explains Catherine Kerninon, General Delegate of EUROSAC. “To ensure that our industry meets the requirements of cement producers and can compete within the packaging market for cement, we investigated the shelf life of the two sack solutions that are used most widely on the market: cement paper sacks and cement plastic sacks.” For the study, typical sack solutions of each type were Paper sacks protect the product quality chosen: a standard cement paper valve sack made and performance for at least 18 months of two paper layers of 80 g and 70 g with a 12 μm in storage.

  • It's in the Bag - Twelve Language Activities ______Dr
    Teaching Threads It's In The Bag - Twelve Language Activities _____________________________________________________________________ Dr. Sharon A. Maroney (2009/1997) Western Illinois University – Quad Cities In advising teachers to increase active learning and reduce passive learning, the fundamental question arises, "But what do you do if you don't do worksheets?" This set of activities begins to answer that question. The activities presented are those that can be prepared easily and inexpensively by classroom teachers; can be adapted across grade or skill levels and subject areas, and used from independent to large- group work arrangements; provide unique ways for students to practice previously learned skills; grab student attention; and are lots of fun! This article presents 12 activities that promote active learning of various language arts skills. Each activity begins with a plain brown paper lunch bag. Activity 1 - There is was! Creative Storytelling This activity is especially successful after students have studied or experienced storytelling and storytellers. Each student, pair, or group of students is given a brown paper sack and directed not to open it until instructed to do so. Then the teacher presents this story starter on the board: "There it was! I just opened my locker after 2nd period, and there it was." The students are instructed to open their bags to find out what was in their locker and to create a story they will tell to the class. Students can tell their stories informally, or they can write their stories, practice their story telling, prepare costumes or props, and perform their stories for the class. Student storytellers can be video or audio recorded.
