Need

The catches of Australia’s rock lobster fisheries are at or near their maximum level. However, adding value to the rocklobster catch will ensure continuing and improved returns for industry. This can be achieved by way of enshrining maximum quality on delivery to the processing factories, maximum survival of live lobsters shipped to overseas destinations, perfect cooking regimes for the portion of the product processed for this market either in Australia or overseas, the maximum recovery during processing, and a continuous maintenance and upgrading of handling conditions, maintaining and improving health and safety conditions, and having respect for community welfare concerns.

The purpose of the Subprogram is to work with industry to identify the opportunities and priorities to enhance products and profitability and to assist industry meet these challenges. It then seeks to identify and support the research needed to provide answers to permit industry to grasp these opportunities, in a cost effective and timely manner. The outcomes of the research are rapidly provided to industry in a form that allows industry to capture the benefits of the research for the Australian industry. Of special importance is the need for the Subprogram to co-ordinate research effort, eliminate duplication of applications and ensure that projects are relevant.

The global market for lobsters now demands Australia to compete effectively in these markets, and the subprogram assists in ensuring that there is capacity to achieve this to allow the industry to maintain and improve its competitive advantage.

Rock Lobster Post Harvest Subprogram: evaluation of alternative processing technologies applicable to crustaceans

Project number: 2005-223

Need

It has been clearly identified by industry members that there is a need for improved and/or alternative processing methods for crustacean species in Australia. Developments in international trade and food standards indicate that a review of current and alternative processing methods is required. Any improvements in the yield and quality of the cooked products will result in a significant market advantage and increased profitability.

Initial studies will focus on western rock lobster as this is a high value market in which a significant portion of the catch is processed. It is proposed that further complementary projects will be initiated to extend this work to other species of crustacea and other technologies over the next few years.

The western rock lobster industry turns over $300 million annually, with 70% of the catch currently marketed as processed product. The major issues with western rock lobster cooking are weight recovery and melanosis reduction. Melanosis occurrence is related to cooking methods (FRDC 2001/235). Currently sulphites, are widely used in the seafood industry to alleviate melanosis, but high levels of sulphites results in a negative impact on flavour and health (McEvily and Iyengar ,1992). Other antibrowning agents, such as Everfresh (4-hexylresorcinol), have not found wide application. For some decades, western rock lobster processors have attempted to refine their traditional cooking method (batch boiling), but to no avail. Recent advances in alternative cooking methods offer the possibilities to improve yields. For example, when compared to boiling, Laitram Machinery Inc., reports typical yield increases of 2% for steamed homarid lobster. A 2% improvement in cooked weight recovery would bring an additional return of approx. $2.6 million per season to the western rock lobster industry. There is a need to address a number of questions regarding the impact of alternative cooking methods on weight recovery and melanosis rates for the western rock lobster. For the first time, these impacts can be assessed objectively using key information gathered in FRDC project 2001/235.

Objectives

1. To determine the standard processing protocol for three alternative cooking method (steam, steam plus pressure and microwave cooking)
2. To investigate factors impacting on uptake of water and antibrowning agents during drowning of rock lobster, correlated to associated weight recovery and melanosis development
3. To evaluate the impact of alternative cooking methods, (microwave cooking, steam, and steam plus pressure) on weight recovery and melanosis rates
4. To evaluate the postproduction sensory quality of rock lobster processed by alternative cooking methods in comparison to rock lobster processed using standard practise (boiling)
5. Optimisation of processing methods
6. Information extension to industry to enable maximal adoption of results

Summary

This project has identified the processing parameters required to optimise rock lobster processing using atmospheric steam cooking to ensure increased weight recovery, reduced melanosis and improved post processing sensory quality. 

The information arising from this project enables processors to maximize their cooked weight recoveries whilst ensuring reduced melanosis through the use of the identified steaming protocol. This will lead to increased profitability and efficient use of the resource is possible through minimising costs of cooking and maximising financial returns due to improved yield and sensory appeal. The product will also be more competitive on the international market due to the improved sensory appeal and ability to reduce use of undesirable chemical treatments (sulphites).

RESEARCH RELEVANCE AND ACCEPTANCE

FRDC is continually asked to fund a wide range of projects in the rock lobster post harvest area. These include studies of post-capture handling, transport, live holding cooking, packing, storing, freezing, Australian and international shipping, etc. To ensure that the investment in R&D results in significant profits for the industry it uses the Subprogram to assist it to measure the quality of science of the application, plan the research with industry partners to ensure improved outcomes, develop a comprehensive extension program, and ensure a high level of adoption of the results.

The Subprogram has achieved a high degree of research coordination between the States and an effective communication strategy to ensure service delivery to the industry. The Subprogram has added value to the FRDC's research investment by managing its project portfolio in this manner. This could not have been achieved without an independent Subprogram Leader and a highl responsive Steering Committee that is represented by industry members across Australia.

RESEARCH EFFICIENCY

Because of the Subprogram there have been substantive savings in the operation of projects and in the funding approved for new projects. The Subprogram ensures that the projects are appropriately costed, involves the industry in the projects where ever possible, and coordinates travel and workshop budjets to ensure a more efficient use of limited research funds.

NEW PROJECT DEVELOPMENT

As an indication of needs. The Subprogram is currently examining projects looking at:

1. Designing improved baskets for transporting both western and southern rock lobster lobsters. This project will be developed mainly with non FRDC funding.

Basket designs vary widely in the industry. The were developed add-hock all over different parts of the fisheries and all over Australia. In recent years there have been many modifictions to original designs as fishers attempted to transport ever increasing numbers of lobsters in a condition 'suitable for live export'. A better designed basket could provide financial savings to fishers and processors, and perhaps make them an interchangable item, similar to the use of wooden pallets in other industries. In addition, a better basket could assist with health and saftey issues, becuse many of the present baskets in use result in excessively heavy loads being carried, which may cause back damage.

2. Solving the “pink lobster” problem (2003/243)in western rock lobsters which is causing problems for both the wild fishery and processors.

Lobsters with pink flesh are difficult for processors to sell and the definiely get a reduced price. This is also a problem for fishers who, knowing of the processors problems, often tend to discsrd these lobsters at sea. It is mainly a western rock lobster problem but it does occur on a small scale in southern rock lobsters in SA.

3. Value adding the southern rock lobster catch by optimising flesh quality of uder valued large lobsters for the sashimi market (2003/242).

Large southern lobsters are difficult if not impossible to sell and if the are sold it is a very low prices. The possibility of value adding to these lobsters by 'preparing them' for the sashimi market is to be examined.

4. Production a booklet assisting sales of rock lobsters by advising overseas buyers how best to hold live rock lobsters; and documenting the operations of the market in Hong Kong for southern rock lobsters to assist Australian marketers from South Australia, Victoria and Tasmania.

5. The cooking project 2001/235 will lead to dramatic new projects after completing of this study. Progress in this project has impressed the industry and clearly indicated that significant improvements improvements can be made in this area. The cooking techniques in practice can greatly improved. Innovate methods such an microwave cooking will be investigated.

Other projects will be developed after identification and consultation with industry. In all cases the Subprogram seeks quality scientific studies using innovative approaches, with maximum cost effectiveness.

Summary

An independent Subprogram Leader, and a highly responsive Steering Committee, that is composed of industry experts from across Australia have provided an effective and efficient system for directing relevant research activities to ensure continued and increased profitability for the Australian rock lobster fisheries. The Steering Committee, under the Subprogram Leader’s direction, worked as an integrated group, rather than a collection of individuals, and carefully selected and recommended projects for funding, and then followed their progress and offered advice to principal investigators in the national interest. The industry representatives on the Steering Committee have also acted to provide research facilities within the industry as the best locations to conduct research, and ensuring the uptake of successful projects as soon as they occur.

The research conducted by the Subprogram has continued to significantly improved Australia’s understanding of the physiology and biochemistry of lobsters, from the time of capture through to processing in a variety of product forms. This is of considerable assistance in investigating methods of better handling, cooking, and/or processing lobsters for live export.
