The food processing industry is growing with retail and catering supply chains. With the rising complexity of food products and the need to address food customization expectations, food processing systems are progressively shifting from production line to job-shops that are characterized by high flexibility and high complexity. A food job-shop system processes multiple items (i.e. raw ingredients, toppings, dressings) according to their working cycles in a typical resource and capacity constrained environment. Given the complexity of such systems, there are divergent goals of process cost optimization and of food quality and safety preservation. These goals deserve integration at both an operational and a strategic decisional perspective. The twofold purpose of this paper is to design a simulation model for food job-shop processing and to build understanding of the extant relationships between food flows and processing equipment through a real case study from the catering industry.

The authors designed a simulation tool enabling the analysis of food job-shop processing systems. A methodology based on discrete event simulation is developed to study the dynamics and behaviour of the processing systems according to an event-driven approach. The proposed conceptual model builds upon a comprehensive set of variables and key performance indicators (KPIs) that describe and measure the dynamics of the food job-shop according to a multi-disciplinary perspective.

This simulation identifies the job-shop bottlenecks and investigates the utilization of the working centres and product queuing through the system. This approach helps to characterize how costs are allocated in a flow-driven approach and identifies the trade-off between investments in equipment and operative costs.

The primary purpose of the proposed model relies on the definition of standard resources and operating patterns that can meet the behaviour of a wide variety of food processing equipment and tasks, thereby addressing the complexity of a food job-shop. The proposed methodology enables the integration of strategic and operative decisions between several company departments. The KPIs enable identification of the benchmark system, tracking the system performance via multi-scenario what-if simulations, and suggesting improvements through short-term (e.g. tasks scheduling, dispatching rules), mid-term (e.g. recipes review), or long-term (e.g. re-layout, working centres number) levers.

The food and beverage industry, particularly the agro‐processing and packaging industry, plays a critical role in the economies of Latin America and Caribbean countries. To remain competitive and to increase competitiveness, companies operating in this industry must achieve operational efficiency – where one contributing factor would be the efficient management of their work‐in‐progress (WIP) inventories.

Constructs from related manufacturing management research areas such as manufacturing strategy and coordination theory, are incorporated into a conceptual framework to examine the reasons WIP are needed in food plants. The framework is used to inform the development of an audit tool, which is applied in a case study.

An audit tool is proposed, which can be used by practitioners to review the structural and infrastructural decisions that impact WIP.

The audit tool is applied in one case study. Further application of the tool will test its overall comprehensiveness.

The audit tool can be used as part of a structured decision making process.

The paper brings together a number of constructs to create an audit tool that can be used in both greenfield and existing plants in the food industry.

The purpose of this paper is twofold: first, it aims to investigate how salt and sugar reduction in foods due to the pressure from the emerging food regulations will affect the physico-electrical properties (PEPs) of orange juice and tomatoes during a selected PEP-dependent thermal processing. Second, the authors are keen to understand how variations in salt and sugar ingredients will affect the time-temperature processing requirements.

PEPs of the samples (orange juice and tomatoes) were measured using the KD2 thermal analyser and RS conductivity metre. Both samples with varying salt and sugar levels were subjected to ohmic heating processing using a 10 kW ohmic heater. Dehydration rates and processing times for pasteurisation were obtained.

Electrical conductivity increases with added salt in tomato puree but decreases with added sugar in orange juice. Statistical evidence confirmed significant changes in heating rates and processing times of tomatoes and orange juice as their relevant salt and sugar levels change. Reduction in salt content in tomato puree led to increase in time and energy for the thermal processes. While reduction in added sugar in orange juice results led to reduction in processing time and energy requirement for the processing operation.

The study is limited to small change in salt and sugar variations in order to reflect recommended limits. There were therefore no significant changes in thermal conductivity for the range investigated. Also this study is focussed on two food products.

Current pressure on the need to reduce salt and sugar in foods necessitates research to increase food processing industry insight into the process and product impacts of such recipe changes, with particular regard to processing efficiency and product safety and quality.

This study represents an attempt to understand the impact of salt and sugar variations on properties and processing requirements of tomato puree and orange juice.

The connotations, associations, custom and usages of a name often give to it an importance that far outweighs its etymological significance. Even with personal surnames or the name of a business. A man may use his own name but not if by so doing it inflicts injury on the interests and business of another person of the same name. After a long period of indecision, it is now generally accepted that in “passing off”, there is no difference between the use of a man's own name and any other descriptive word. The Courts will only intervene, however, when a personal name has become so much identified with a well‐known business as to be necessarily deceptive when used without qualification by anyone else in the same trade; i.e., only in rare cases. In the early years, the genesis of goods and trade protection, fraud was a necessary ingredient of “passing off”, an intent to deceive, but with the merging off Equity with the Common Law, the equitable rule that interference with “property” did not require fraudulent intent was practised in the Courts. First applying to trade marks, it was extended to trade names, business signs and symbols and business generally. Now it is unnecessary to prove any intent to deceive, merely that deception was probable, or that the plaintiff had suffered actual damage. The equitable principle was not established without a struggle, however, and the case of “Singer” Sewing Machines (1877) unified the two streams of law but not before it reached the House of Lords. On the way up, judical opinions differed; in the Court of Appeal, fraud was considered necessary—the defendant had removed any conception of fraud by expressingly declaring in advertisements that his “Singer” machines were manufactured by himself—so the Court found for him, but the House of Lords considered the name “Singer” was in itself a trade mark and there was no more need to prove fraud in the case of a trade name than a trade mark; Hence, the birth of the doctrine that fraud need not be proved, but their Lordships showed some hesitation in accepting property rights for trade names. If the name used is merely descriptive of goods, there can be no cause for action, but if it connotes goods manufactured by one firm or prepared from a formula or compsitional requirements prescribed by and invented by a firm or is the produce of a region, then others have no right to use it. It is a question of fact whether the name is the one or other. The burden of proof that a name or term in common use has become associated with an individual product is a heavy one; much heavier in proving an infringement of a trade mark.

The purpose of this paper is to evaluate the hygienic design of a scalable unit for supercritical carbon dioxide drying of food.

For the purpose of this study, a checklist has been developed, covering requirements from sanitary standards and industry-tailored guidelines. Beyond hygienic design, failure mode and effects analysis of the results were performed to assess the potential food safety risks that may arise from failures to hygienic design requirements.

The overall score of the hygienic design was 46 percent. This kind of evaluation revealed two types of nonconformities. The first type was related to inadequate sanitary procedures. The second type was associated to design failures.

The highest risk was designated to problems related to cleaning and sanitation followed by risks associated with the formation of dead zones and biofilms.

This study provides valuable insight to engineers and food technologists on hygienic design issues.

Application of a similar methodology was used for evaluating hygienic design of other non-thermal food technologies.

With the drastically changed pattern of the retail food trade in recent years in which the retailer's role has become little more than that of a provider of shelves for commodities, processed, prepared, packed and weighed by manufacturers, the defence afforded by the provisions of Section 113, Food and Drugs Act, 1955 has really come into its own. Nowadays it is undoubtedly the most commonly pleaded statutory defence. Because this pattern of trade would seem to offer scope for the use of the warranty defence (Sect. 115) in food prosecutions it is a little strange that this defence is not used more often.

Some months ago a national organisation established to keep a watchful eye on the Nation's diet expressed concern over the eating trends of people in what to them appeared to be developing inbalances of necessary nutrient factors and the inadeuacy not so much of calories and energy values but in the nature and quality of main food factors. It was recommended that the national diet should be improved, but the authorities pointed to the National Food Survey results to show that the diet was not deficient; that the average daily intake of protein, vitamins, minerals and overall energy requirements were satisfied; all of which is true for the not‐too‐generous levels set. Even the pensioner households included in the Survey sample appear well‐fed. What causes concern is the year‐by‐year decrease in staple foods consumed—milk, red meat, bread, fresh vegetables—and the heavy reliance on refined, processed foods. In its annual reports on NFS reviews, the BFJ has almost monotonously referred to this downward trend. Individual NFS Reports do not reveal any serious deficiencies, as yet, but in the trend over the years—and herein lies the real value of the Survey and its data—few if any of the changes have been for the better; movements in food groups have tended to be downwards. If these trends continue, the time must surely come when there will be real deficiencies; that substitution within a food group cannot make good essential foods severely rationed by high prices.

The use of lubricants in food production and processing is widely known. Over time, the regulations and requirements for lubricants in food machinery have evolved to include a wide variety of product technology. This technology includes many synthetic based formulated lubricants. This paper will focus on the types of lubricants available for use in the food industry, as well as the benefits and potential drawbacks of each lubricant type. It will also address the changing legislation surrounding the use of lubricants in food manufacturing and processing equipment.

This new measure of consumer law of some forty‐odd sections, a short Act by present standards but as far‐reaching as any legislation since the war, establishes a code of conduct in commerce and trade which few will be able to ignore, from the manufacturer down to the counter‐hand. Operative from November 30th of this year, traders will require to urgently consider their sales practices, advertising, labelling and their trade descriptions; sales staff will need to be instructed in their new responsibilities. The new law is not just for consumer‐retailer transactions, but extends to trade between different branches of all trades, so that a retailer will be protected against misleading descriptions and misrepresentations by a manufacturer and the latter against misdescriptions of ingredients or components.

Highlights the lack of detailed published information on the use of infra‐red heating in food processing in the UK. Provides a number of answers based on conclusions from a recent seminar. These are a reluctance of users to reveal information to their competitors of where it is used, perceived technical problems (some infra‐red heaters contain glass) and fears on energy costs which restrict its wider use and lack of knowledge of the technology by food processing plant manufacturers. Discusses the attributes of infra‐red heating and gives some examples of its use (not all in the UK) for food processing.
