Abstract Background/motivation for the study: Since the late 1970s, China has seen an unprecedented growth in its economy and with that growth follows the improvement in the quality of life for a majority of its citizens. Naturally, people  will focus more on the quality of their daily nutritional products as a result. One of the technologies for preserving food products is called Cold Chain Logistics, which is deal with processing, transporting and storing food products. Despite its rapid development in China, the Cold Chain Logistics system still has many problems to be dealt with by its new users thus exploring how it can better adapt to a more demanding consumers is very interesting. We will use Henan Province QI County Yongda Food Industry CO.LTD as an example for illustrating how a food industry company can effectively manage its Cold Chain Logistics system.    Purpose: The purpose of  this thesis is to first learn about in Cold Chain Logistics in the food industry through different literatures and second, to understand the main differences in Cold Chain Logistics in the food industry when China is  compared with USA and Japan  and third,  to help Cold Chain Logistics in China be improved through technology and management.    Methods: In order to answer the purposes of this thesis, firstly, we read and write an extensive literature review related to this thesis. Secondly, we use Yongda Company as a case study.  Interviews with the one manager and two employees are major source of data collection.    Findings: We present and compare the differences between Chinese, American and Japaneses’ implementation of systems through various angles. China's Cold Chain Logistics is  still  in the development stage. The whole Cold Chain Logistics has not matured. Furthermore, a  case study  is conducted on how Yongda Company can have many significant advantages over its competitors in Cold Chain Logistics and how  their techniques and management styles can benefit other companies if applied correctly throughout China.     Contributions: This thesis will show that how to management Cold Chain Logistics in the real company.    Key words: Cold Chain Logistics, CCL, Yongda Company, food industry.

Idag transporteras kylda livsmedel, i Sverige, inom ett temperaturintervall på +2 °C - +8 °C. I vilken temperatur som animaliska livsmedel ska hanteras i regleras i lagstiftningen och varierar mellan +2 °C - +7 °C. Många kylskåp, både hos butik och konsument, är inställda på+8 °C. Till följd av detta är den stora majoriteten livsmedel, på förpackningen, markerade med en förvaringstemperatur på +8 °C. På senare år har diskussioner förts angående en sänkt temperatur i kylkedjan. Anledningen till detta är att överkomma matsvinnet. Forskning pekar på att ett livsmedels hållbarhet är starkt beroende av dess förvaringstemperatur. Hastigheten på mikrobiell tillväxt sjunker nämligen med lägre temperaturer. År 2020 träder en ny förordning om fluorerade växthusgaser (fgasförordningen)i kraft som förbjuder installation och påfyllning av kommersiell utrustning innehållande köldmedier med högre Global Warming Potential-faktor än 2500. Detta innebär att butiksledet i stor utsträckning kommer tvingas byta ut sina äldre kylsystem. Med nya kylsystem kan en lägre temperatur garanteras. För att vara väl förberedda ställer sig transportbranschen frågan vilka konsekvenser en sänkttemperatur kan tänkas föra med sig i deras del av kedjan. Problematiken grundar sig i att en del livsmedel kan ta skada av temperaturer nära fryspunkten. För att skydda dessa livsmedelkan transportören använda sig av produktskydd på kylkänsliga livsmedel. En annan beprövad metod är att dela in livsmedlen i flera temperaturzoner. Arbetets teoretiska bidrag är att det sammanställer tidigare forskning på områden inom livsmedelsegenskaper vid nedkylning, multitemperatursystem och produktskydd samt semistrukturerade intervjuer med experter inom sina respektive områden. Vidare undersöksäven kylkedjans uppbyggnad och dess aktörer. Perspektivet i rapporten utgår från ett av de större transportföretagen inom tempererad logistik i Sverige. Arbetets praktiska bidrag är baserat på en fallstudie som tillsammans med det teoretiska bidraget ligger till grund för en redogörelse över tänkbara konsekvenser. Analysen visar på att en del livsmedel, för att inte komma till skada och riskera kassation, måste skyddas. Antingen genom flera temperaturzoner eller genom produktskydd. Bådaalternativen kommer med för- och nackdelar. Att addera flera temperaturzoner för med sig investeringar i form av mellanväggar och kylsystem samt komplicerar livsmedelshanteringen. Flera temperaturzoner kan emellertid säkra ett livsmedels kvalitet. För produktskydden existerar det inget returlogistiksystem och ett system kan bli mycket kostnadsdrivande att upprätthålla. Slutsatsen är att en kombination av de båda lösningarna är att föredra men att branschöverskridande samarbete krävs för att samtliga parter ska gynnas. / Chilled foodstuffs are today transported within a temperature interval of +2 °C - +8 °C in Sweden. The correct temperatures in which foodstuffs with animal origin should be handled in are regulated by law and diverges between +2 °C - +7 °C. Many refrigeration systems in grocery stores and consumer’s homes are set at +8 °C. The great majority of foodstuffs are, as a result of this, on the packaging marked with a storage temperature of +8 °C. To be well prepared, the transport industry ask themselves which consequences might occur in case of a reduced temperature in the cold chain. The main reason for this is to overcome food waste. Research shows that foodstuffs durability is highly dependent on its storage temperature. The rate in which microbial growth occur drops with falling temperatures. In2020 a new EU regulation enters in to force which regulates the use of refrigerants with higher Global Warming Potential factor than 2500. The grocery stores have to, as a result of this, replace many of their older refrigeration systems. Regulating lower temperatures won’t be an issue with new modern equipment. As a result of this they can guarantee lower temperatures on foodstuff. To be prepared for what might come, the transport industry wants to know what consequences a lower temperature might bring along in their part of the cold chain. The main issue is that some foodstuff might be harmed in temperatures close to the freezing point. The use of protective coatings could offer shelter for cold sensitive products. One other proven method is to allocate foodstuff in different temperature zones. This thesis theoretical contribution compiles earlier research in areas such as foodstuffs characteristics when refrigerated, multi temperature systems, protective coatings and semi structured interviews with experts within their fields. It further examines the cold chain and the stakeholders within it. The focus of the thesis is thru the perspective of one of the major transport companies within cold chain logistics in Sweden. The practical contribution is based on a case-study together with the theoretical contribution which states consequences that possibly can occur along the transport company’s part of the cold chain. The analysis shows that, to minimize the risk of cassation, some foodstuffs need protection. Either thru multiple temperature zones or with protective covers. Both alternatives comes with advantages and disadvantages. To add temperature zones are associated with investments in the form of separable walls and cooling systems together with an increase in logistic complexity. Multi temperature systems can however secure the quality in a foodstuffs quality. The issue with protective covers is that there’s no return logistics system in place and such a system can be very expensive to uphold. The covers do however offer protection from outer temperature influence. The conclusions states that a combination of both solutions might be suitable. To accomplish this however requires collaboration over company and industry borders if all stakeholders are to be beneficial.

<p>  </p> <p>Cold chain logistics comprise a large portion of transported pharmaceutical medications and raw materials which must be preserved at specified temperatures to maintain consumer safety and efficacy. An immutable record of temperatures of transported pharmaceutical goods allows for mitigation of temperature-related issues of such drugs and their raw components. The recording of this information on a blockchain creates such an immutable record of this information which can be readily accessed by any relevant party. This can allow for any components which have not been kept at the appropriate temperatures to be removed from production. These data can also be used as inputs for smart contracts or for data analytic purposes. </p> <p>A theoretical framework for such a system, referred to as “TempEnsure” is described, which provides digital capture of the internal temperature of temperature-controlled shipping containers. The data are recorded in a blockchain system. Real world testing of this system was not possible due to monetary constraints, but the functional elements of the system, as well as potential improvements for the system, are discussed.</p>
