Development Of Goose Liver Deep Processing Products

In recent years,China has become the world's largest country of geese.However,goose liver product form is single,which is main processed to be sauce halogen products and cured products,and with poor taste flavour.In addition to that,because of the low utilization,a large amount is used as animal feeds or thrown.The aim of my study is to improve the goose liver utilization,and then tap its potential,by deep processing the goose liver.Firstly,I designed a questionnaire survey to explore consumer's awareness of goose liver in the infant food,and the potential market value of goose liver development for infants and toddlers in order to provide a basis for later product development.On this basis,by orthogonal experiment to optimize the goose liver deep-processing products(infant nutrition and goose liver goose liver and intestine)of the optimal formula,and the determination of the nutritional content of goose liver two deep-processed products to clarify the nutritional value of the product.In order to provide a theoretical basis and technical guidance for the development and utilization of liver and other animal by-products.The specific research content and results are as follows:1.Feasibility investigation of goose liver as infant food supplementA total of 660 questionnaires were distributed in supermarkets,residents' communities,streets and on the Internet in Nanjing,Jiangsu province.There were 630 valid questionnaires with an effective rate of 95.5%.The survey results showed:from the perspective of the recognition of goose liver,only 8.6%of respondents had a good understanding of the richness of goose liver nutrition needed for infants and young children.from the perspective of the supply form of infant foods,there were 16.7%respondents opted for home-made complementary foods.In households with home-grown or purchased goose liver products,65.2%of infants added liver paste as a supplementary food after 7 months.59.0%interested in goose liver products and considering buying.According to the survey results,the nutritional value of goose liver should be strengthened,enrich the types of complementary foods,and develop complementary food products for infants hat are easy to carry and eat.2.Preparation of infant goose liverComprehensive sensory evaluation,texture properties and rheological properties,orthogonal experiments were used to explore the influence of formulation process(corn starch content,olive oil volume,ice water volume)on the quality of goose liver.The results showed that the quality of goose liver was best when 6%of corn starch,10%of olive oil,and 110%(the percentage is based on the quality of goose liver)of ice water were added.The goose liver flavor coordination under this formula ratio has good spreadability.The goose liver has a protein content of 12.71%,an essential amino acid content of 4.971 mg/100 g,n-6/n-3 is 0.091 an iron content of 0.576 mg/kg,a calcium 0.433 mg/kg,and a zinc 0.257 mg/kg,and the product meets the standards of canned supplementary food for infants(GB 10770-2010).Thus,goose liver developed more in line with people's pursuit of safe,healthy,high quality food supplement.3.Development of nutrition liver goose sausageThe sensory evaluation,texture properties,and food rheology were combined to optimize the formula of foie gras and optimize the nutritional composition.The results show:with goose liver 50%,olive oil 20%,corn starch 4%as the main material,the development of goose liver sausage showed colour uniformity,full intestinal bodies,flexibility and flavour coordination.The goose liver sausage contained 13.12%of protein,2.065 mg/100 g of essential amino acid,52.79%of monounsaturated fatty acid ratio,PUFA/SFA is 0.58,low n-6/n-3 ratio,476 mg/kg of iron,380 mg/kg of calcium,241 mg/kg of zinc.These results suggest that,goose liver developed more in line with people's pursuit of safe,healthy,high-quality food.
