Influence of Temperature and Freezing Time on Broiler Chicken Meat Colour
Due to the fact that meat colour represents an important aspect for sensorial evaluation of any food product,research in the field of poultry meat processing regarding efficient methods for hoarding/storage on long term ofindustrially slaughtered poultry carcasses approaches a continuous finding/optimization of certain solutions foravoiding negative consequences due to oxidation, which could include colour loss and/or its modification.The current study aimed to evaluate the effects of three storage regimes differing by temperature and time(L = -14°C, 30 days; L = -16°C, 60 days; L = -18°C, 90 days) on three anatomical cut regions (breast, upper thighand lower thigh), to characterize the colour of broiler chicken meat. Objective description of colour for frozen anddefrosted chicken meat was realised through the CIEL*a*b* Cartesian coordinate system.Overall, the preservation method determines a higher luminosity at samples gathered from L batch chickencarcasses for breast and upper thigh musculature, and L for lower thigh musculature in comparison with thecounterparts from the other experimental batche
Selected Biometric Characteristics of Wild Boar (Sus Scrofa Ferus) in North-East Romania
Our study analyzed selected biometric characteristics from 117 wild boars (Sus scrofa ferus) harvested during 2008 - 2014 in the Frasin and Marginea Forest hunting ground districts of Suceava County. Hunted boars were measured individually for head-body length (cm), height at withers (cm), length of metatarsus (cm), ear length (cm), tail length (cm) and body weight (kg) in accordance with their age-class and gender. These characteristics give information on the growth and development of wild boars and on the quality of their habitat. It was found that the average carcass weight was: piglets - 28.4 kg, yearling - 78.1 kg, subadults - 102.9 kg. The results show a faster body growth in females during their first year, while males make up for the weight difference in their 2nd and 3rd year. Statistical differences shown that males differentiate significantly to females by weight, body length, height at withers and length of metatarsus (P < 0.05) starting with their second year of life. The results regarding growth dynamic go along with the changes in boar’s social life, when the males are forced to leave and form smaller groups
The importance of technological parameters on the sensory quality of smoked mackerel
Fish meat, through its biological and chemical characteristics, is, for humans, nutritious food with many benefits on the
body and is suitable for industrialization in various forms.This study aimed to make assortments of smoked mackerel,
applying a differentiated technology, ending with a sensory evaluation of the product obtained to examine the effect of
processes and recipes applied to sensory characteristics such as appearance, texture, color, and aroma and palatability of
products.The study material was purchased from a fish warehouse and transported in specific conditions (0-4°C) the
next stage consisting of staining and differentiated maturation according to the established technological file and
smoking in the meat processing microsection within USV Iași. Thus, the assortments were marinated for 12 and
relatively 24 hours in a vacuum.Sensory evaluation is a vital operation in the development of new products and for this
evaluation, 45 evaluators were part of the study, answering a questionnaire to identify the differences perceived after
different maturation presented in the datasheet.The samples matured for 24 hours were the most appreciated by the
evaluators obtaining the highest averages for the sensory characteristics of appearance, texture, color, and aroma.
According to the sensory evaluation, the samples from experimental group 2 obtained higher values than the sample
from experimental group 1
The role of sensory evaluation in food quality control, food research and development: a case of cream cheese study
Sensory evaluation is a method of analysing, measuring and interpreting sensory perception responses to food, based on
the five human senses, charac terised, in line with other scientific methods of measurement, by precision, accuracy and
sensitivity. The material studied consisted of six varieties of cream cheese purchased on the commercial market and
produced by a usual technological process. The sensory evaluation session involved assessment of colour, aroma,
texture and taste by a group of 20 tasters over three series of tastings. From a ranking point of view, in descending
order of the average scores obtained in the sensory evaluation of the characteristics of appearance, colour, texture,
smell, taste and creaminess, the samples can be classified as follows: Philadelphia (S2), Hochland (S3), LaDorna (S1)
Goldessa (S5), Delaco (S6) and KClassic (S4)
Food fraud prevention as an active tool in meat industry: a case study of poultry slaughterhouse
Worldwide latest food fraud incidents have emphasized the need to reinforce food fraud prevention across the global supply chain, which again is essential not just to protect public health, but also to regain weakened consumer trust in foods, in an economic context where entrepreneurs and regulators acknowledge that confidence is the cornerstone of efficient and productive economies. Unfortunately, current food safety and quality management systems were not initially intended to prevent fraud. Prevention of food fraud involves a particular approach: it must take into account vulnerability assessments and formulate a food fraud mitigation plan, that needs to be continuously updated, being correlated with national and international context on this subject and the fact that food fraud typically appears when the opportunity and the motivation of food crime are strong and the probability of being detected as well as the penalties are
minimal. The central objective of this paper was to develop a functional analysis tool starting with a pre-existing "NSF Fraud Security Model" version, designed to support the large reputable food retailers and authorities in the prediction of potential for fraudulent activity in a variety of products. This case study, focused on three key strategic elements: the prediction, prevention and management of the food fraud mitigation plan in accordance with Guidelines for Implementation of the GFSI recognized schemes. The outcome of this project is a functioning prototype, a concept built over the past 2 years via collaborative sessions with project team members and tested for input from industry and
regulatory representatives. This analysis provides a framework for evaluating the role of science and technology in identification, mitigation, and then prevention
