The aim of this study on Strasbourg-type fresh smoked sausage and farmhouse pâté was to identify consumer sensory acceptance by a boar taint-sensitive consumer tasting panel. Backfat was selected from non-castrated boar carcasses with boar taint
detected at the slaughter-house by chemical analysis of scatole and androstenone content. Nine sausage batters of increasing
scatole and androstenone content were produced, along with a control mix made from sow backfat. The all-round assessment
of the pâté for low-androstenone-content batches (less than 1 µg androstenone per g fat) was equivalent to the control batch
score. At upwards of 1.5 µg androstenone plus 0.15 µg scatole per g in the backfat, there is a sharp drop in all-round assessment
of the end-product.
Our analysis on Strasbourg-type fresh smoked sausage found that androstenone and scatole concentration had no effect on
all-round consumer assessment scores. The recipe for Strasbourg-type fresh smoked sausage made with salt-cured backfat and
soaked in liquid smoke appears to heavily influence product taste and odour and to mask boar taint.

Valorisation du gras de porcs non castrés à différents niveaux d’odeurs dans des saucisses fumées et pâté
L’étude visait à évaluer l’acceptabilité de la saucisse type Strasbourg fumée et du pâté de campagne par un panel de consommateurs
sélectionnés comme sensibles aux odeurs de verrat.
Du gras de bardière issu de carcasses de mâles non castrés identifiées comme odorantes à l’abattoir par analyse chimique des taux de
scatol et d’androsténone a été sélectionné.
9 mêlées de niveaux croissants en androsténone et scatol ont été réalisées ainsi qu’une mêlée témoin à partir de gras de femelles.
L’appréciation globale du pâté fabriqué avec les lots faiblement chargés en androsténone (valeur en androsténone inférieure à 1 µg/g
de gras) est équivalente au lot témoin.
A partir d’une valeur en androsténone de 1,5 µg associée à des valeurs en scatol supérieures à 0,15 µg dans le gras, on observe une
chute nette de l’appréciation générale du produit.
Concernant la saucisse de Strasbourg fumée, l’IFIP a mis en évidence que la concentration en androsténone et scatol n’a pas d’effet
sur l’appréciation globale par le consommateur.
La recette de la saucisse de Strasbourg fumée élaborée à partir du gras de bardière bénéficiant d’une cuisson en salaison ainsi qu’un
trempage des saucisses dans de la fumée liquide, semble influer fortement sur l’odeur et le goût, et masquer l’odeur de verrat.

Valorisation du gras de mâles non castrés en saucisse fumée et pâté
Introduction
Here, the project used a boar taint-sensitive consumer tasting panel in order to identify the threshold of consumer
sensory acceptance on two charcuterie products containing a high percentage of fat rich in increasing scatole and
androstenone concentrations: farmhouse pâté and soft-textured sausage. These two products were chosen in consensus with French slaughterhouse and salt curing industry
professionals. One is eaten hot, whereas the other is eaten
cold.
Material and methods
Selection objectives on the low-to-high-taint
fatback samples to be tested in the recipes
This research programme consisted in recovering fatback
from non-castrated boar carcasses with boar taint detected
at the slaughterhouse by chemical analysis of scatole and
androstenone content, for end-purpose of incorporating
them into two charcuterie products: farmhouse pâté and
soft-textured sausage. The two odour-active compounds
were assayed by HPLC at the INRA’s Saint-Gilles-based lab
Over a three month period, fatback samples were taken
from all non-castrated male pigs under the UTOPIGE
genetics programme slaughtered at the Cooperl slaughterhouse in Montfort-sur-Meu and from non-castrated pigs
under IFIP research programmes at the Romillé experimental pig farm slaughtered at the Gatine Viandes slaughterhouse in La Guerche-de-Bretagne (i.e. 380 non-castrated
76
Bardière découennée
boars sampled, taking 1 to 2 kg fatback per pig). All fatback
samples were vacuum-packed then frozen at -18°C until
odour-active compound analysis by the INRA.
Once the INRA had characterized the androstenone/scatole
content of each fatback, the samples were ready to be taken
to the Maisons-Alfort-based technological trialling space
and manufactured into farmhouse pâté and Strasbourgtype fresh smoked soft-textured sausage by incorporating
this odour-profiled fatback into the recipes.
The odour-profiled fatback was incorporated into the
farm-house pâté and soft-textured sausage recipes at low
to increasingly high rates of androstenone/scatole content
as schematized in Table 1.

Fatbacks finally selected
Working from 380 vacuum-packed fatbacks that were subsampled and analyzed by the INRA to determine androsten-one and scatole content, we formed 9 batches that are
characterized by the following androstenone–scatole profiles (see Table 2).
In relation to our objective as set out in Table 1, a fairly
drastic selection scheme had to be applied on the fatback
samples (see Figure 1, Distribution of samples analyzed),
with only 11% of the 380 samples available ultimately being
selected for inclusion into homogeneous batches with the
lowest standard deviations possible.
A letter of intent has been drafted by the EU and signed by
the majority of EU pork industry value chains (European
Declaration on alternatives to surgical castration of pigs).
Under this agreement, we are committed to work towards
ending the castration of pigs by 2018.
LBreeding non-castrated male pigs results in 3–5% of boar
carcasses naturally presenting a musky pheromone-dense
odour that puts off a number of consumers, according
to claims from the leading countries engaged in rearing
non-castrated boars to sexual maturity. There is intensive
research to develop a technology for in-slaughterhouse
detection and out-sorting of carcasses with boar taint by
rapid chemical analysis of odour-active compounds or
sensory analysis by trained profilers. The IFIP has led
numerous sensory testing studies (Chevillon et al. 2010,
Bonneau et al. 2012) to validate the acceptability thresholds
of various ready-processed or fresh pork products based
on chemical levels of the odour-active compounds scatole
and androstenone measured in pig fat. No study to date
has assessed the sensory acceptability of high-taint fat from
non-castrated boar carcasses with boar taint detected at the
slaughterhouse by chemical analysis of odour compounds.

Consumer acceptability test
We elected not to set rules on gender ratio as the fact that
women are more androstenone-sensitive than men would
have made it difficult to keep a balanced gender ratio.
Les dégustations ont eu lieu selon les normes V09.105 dans
le laboratoire d’analyse sensorielle Actalia situé à Caen.
Les produits ont été présentés en conditions de lumière du
jour.
Chaque consommateur a reçu, pour chaque lot, une saucisse de Strasbourg entière réchauffée dans l’eau bouillante
et immédiatement servie à une température de 60 °C.
For tests on the farmhouse pâté, each consumer was given
one 50 g slice of pâté per batch served at a temperature of
6–7°C with a salt-free cracker on which to taste the product.
The consumer taste tests were completed by two groups
counting close to 100 different people— consumers that
participated in the three sausage tests were excluded from
participating in the pâté tests.
The IFIP planned to run hedonic-scale taste tests on the different batches by androstenone-sensitive consumers. The
rationale was that although most people are scatole-sensitive,
50% of consumers are either androstenone-anosmic or can
pick up the smell but do not find it offensive.
Consequently, for this study, the IFIP invited ACTALIA to
preselect (ahead of the test sessions) a panel of androstenone-sensitive and androstenone-averse people.
Three hedonic like/dislike tests were led per product. At
each per-product test, the androstenone-sensitive consumers
scored four batches as per Table 3 below.
The consumers were regular charcuterie buyers aged
over 25 with a like-preference for knack-type sausages/
farmhouse pâté.

Figure 7: Taste assessment results for tests 1, 2 and 3 on the pâté
clearly evidence the effect of androstenone content × scatole
content interaction on the acceptability of farmhouse pâté.
Other odour-active compounds responsible for boar taint-like
smell may be implicated in this eaten-cold food.
Discussion
In conclusion, the consumer as selected in this trial (as
androstenone-sensitive) does not register a very dislikeable
taste or smell in three batches of Strasbourg-type fresh
smoked sausage fabricated from increasingly boar taint
compound-rich intact boar fatback compared to a control
batch of sausages fabricated with sow fatback.
This conclusion certainly holds true under our experimental testing conditions. i.e. with fatback used as raw material.
Some meat-curers may want to opt for jowl fat which may
be more odour compound-packed due to the fat-embedded
salivary glands. These salivary glands are more androstenone
and scatole-rich than the fatty tissue.
Whittington et al (2011) measured far higher androstenone
concentrations in a composite sample of “fat and muscle
from the head along with salivary glands” than in the fatback from the same pig carcasses.
